+# Contributing to Buildah
+
+We'd love to have you join the community! Below summarizes the processes
+that we follow.
+
+## Topics
+
+* [Reporting Issues](#reporting-issues)
+* [Submitting Pull Requests](#submitting-pull-requests)
+* [Communications](#communications)
+* [Becoming a Maintainer](#becoming-a-maintainer)
+
+## Reporting Issues
+
+Before reporting an issue, check our backlog of
+[open issues](https://github.com/projectatomic/buildah/issues)
+to see if someone else has already reported it. If so, feel free to add
+your scenario, or additional information, to the discussion. Or simply
+"subscribe" to it to be notified when it is updated.
+
+If you find a new issue with the project we'd love to hear about it! The most
+important aspect of a bug report is that it includes enough information for
+us to reproduce it. So, please include as much detail as possible and try
+to remove the extra stuff that doesn't really relate to the issue itself.
+The easier it is for us to reproduce it, the faster it'll be fixed!
+
+Please don't include any private/sensitive information in your issue!
+
+## Submitting Pull Requests
+
+No Pull Request (PR) is too small! Typos, additional comments in the code,
+new testcases, bug fixes, new features, more documentation, ... it's all
+welcome!
+
+While bug fixes can first be identified via an "issue", that is not required.
+It's ok to just open up a PR with the fix, but make sure you include the same
+information you would have included in an issue - like how to reproduce it.
+
+PRs for new features should include some background on what use cases the
+new code is trying to address. When possible and when it makes sense, try to break-up
+larger PRs into smaller ones - it's easier to review smaller
+code changes. But only if those smaller ones make sense as stand-alone PRs.
+
+Regardless of the type of PR, all PRs should include:
+* well documented code changes
+* additional testcases. Ideally, they should fail w/o your code change applied
+* documentation changes
+
+Squash your commits into logical pieces of work that might want to be reviewed
+separate from the rest of the PRs. But, squashing down to just one commit is ok
+too since in the end the entire PR will be reviewed anyway. When in doubt,
+squash.
+
+PRs that fix issues should include a reference like `Closes #XXXX` in the
+commit message so that github will automatically close the referenced issue
+when the PR is merged.
+
+<!--
+All PRs require at least two LGTMs (Looks Good To Me) from maintainers.
+-->
+
+### Sign your PRs
+
+The sign-off is a line at the end of the explanation for the patch. Your
+signature certifies that you wrote the patch or otherwise have the right to pass
+it on as an open-source patch. The rules are simple: if you can certify
+the below (from [developercertificate.org](http://developercertificate.org/)):
+
+```
+Developer Certificate of Origin
+Version 1.1
+
+Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
+660 York Street, Suite 102,
+San Francisco, CA 94110 USA
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+Developer's Certificate of Origin 1.1
+
+By making a contribution to this project, I certify that:
+
+(a) The contribution was created in whole or in part by me and I
+    have the right to submit it under the open source license
+    indicated in the file; or
+
+(b) The contribution is based upon previous work that, to the best
+    of my knowledge, is covered under an appropriate open source
+    license and I have the right under that license to submit that
+    work with modifications, whether created in whole or in part
+    by me, under the same open source license (unless I am
+    permitted to submit under a different license), as indicated
+    in the file; or
+
+(c) The contribution was provided directly to me by some other
+    person who certified (a), (b) or (c) and I have not modified
+    it.
+
+(d) I understand and agree that this project and the contribution
+    are public and that a record of the contribution (including all
+    personal information I submit with it, including my sign-off) is
+    maintained indefinitely and may be redistributed consistent with
+    this project or the open source license(s) involved.
+```
+
+Then you just add a line to every git commit message:
+
+    Signed-off-by: Joe Smith <joe.smith@email.com>
+
+Use your real name (sorry, no pseudonyms or anonymous contributions.)
+
+If you set your `user.name` and `user.email` git configs, you can sign your
+commit automatically with `git commit -s`.
+
+## Communications
+
+For general questions, or discussions, please use the
+IRC group on `irc.freenode.net` called `cri-o`
+that has been setup.
+
+For discussions around issues/bugs and features, you can use the github
+[issues](https://github.com/projectatomic/buildah/issues)
+and
+[PRs](https://github.com/projectatomic/buildah/pulls)
+tracking system.
+
+<!--
+## Becoming a Maintainer
+
+To become a maintainer you must first be nominated by an existing maintainer.
+If a majority (>50%) of maintainers agree then the proposal is adopted and
+you will be added to the list.
+
+Removing a maintainer requires at least 75% of the remaining maintainers
+approval, or if the person requests to be removed then it is automatic.
+Normally, a maintainer will only be removed if they are considered to be
+inactive for a long period of time or are viewed as disruptive to the community.
+
+The current list of maintainers can be found in the
+[MAINTAINERS](MAINTAINERS) file.

-* golang (Requires version 1.8.1 or higher.)
-* bats
-* btrfs-progs-devel 
-* device-mapper-devel 
-* gpgme-devel 
-* libassuan-devel 
-* git 
-* bzip2
-* go-md2man
-* skopeo-containers
+**[Installation notes](install.md)**
 
-In Fedora, you can use this command:
+**[Tutorials](docs/tutorials/tutorials.md)**
 
+## Example 
+
+From [`./examples/lighttpd.sh`](examples/lighttpd.sh):
+
+```bash
+$ cat > lighttpd.sh <<EOF
+#!/bin/bash -x
+
+ctr1=`buildah from ${1:-fedora}`
+
+## Get all updates and install our minimal httpd server
+buildah run $ctr1 -- dnf update -y
+buildah run $ctr1 -- dnf install -y lighttpd
+
+## Include some buildtime annotations
+buildah config --annotation "com.example.build.host=$(uname -n)" $ctr1
+
+## Run our server and expose the port
+buildah config $ctr1 --cmd "/usr/sbin/lighttpd -D -f /etc/lighttpd/lighttpd.conf"
+buildah config $ctr1 --port 80
+
+## Commit this container to an image name
+buildah commit $ctr1 ${2:-$USER/lighttpd}
+EOF
+
+$ chmod +x lighttpd.sh
+$ sudo ./lighttpd.sh
 ```
- dnf -y install \
-    make \
-    golang \
-    bats \
-    btrfs-progs-devel \
-    device-mapper-devel \
-    gpgme-devel \
-    libassuan-devel \
-    git \
-    bzip2 \
-    go-md2man \
-    skopeo-containers
-```
-
-Then to install buildah follow the steps in this example: 
-
-```
-  mkdir ~/buildah
-  cd ~/buildah
-  export GOPATH=`pwd` 
-  git clone https://github.com/projectatomic/buildah ./src/github.com/projectatomic/buildah 
-  cd ./src/github.com/projectatomic/buildah 
-  make 
-  make install
-  buildah --help
-```
-
-buildah uses `runc` to run commands when `buildah run` is used, or when `buildah build-using-dockerfile`
-encounters a `RUN` instruction, so you'll also need to build and install a compatible version of
-[runc](https://github.com/opencontainers/runc) for buildah to call for those cases.

+# Buildah Tutorial 1
+## Building OCI container images
+
+The purpose of this tutorial is to demonstrate how Buildah can be used to build container images compliant with the [Open Container Initiative](https://www.opencontainers.org/) (OCI) [image specification](https://github.com/opencontainers/image-spec). Images can be built from existing images, from scratch, and using Dockerfiles. OCI images built using the Buildah command line tool (CLI) and the underlying OCI based technologies (e.g. [containers/image](https://github.com/containers/image) and [containers/storage](https://github.com/containers/storage)) are portable and can therefore run in a Docker environment.
+
+In brief the `containers/image` project provides mechanisms to copy, push, pull, inspect and sign container images. The `containers/storage` project provides mechanisms for storing filesystem layers, container images, and containers. Buildah is a CLI that takes advantage of these underlying projects and therefore allows you to build, move, and manage container images and containers.  
+
+First step is to install Buildah. Run as root because you will need to be root for running Buildah commands:
+
+    # dnf -y install buildah
+
+After installing Buildah we can see there are no images installed. The `buildah images` command will list all the images:
+
+    # buildah images
+
+We can also see that there are also no containers by running:
+
+    # buildah containers
+  
+When you build a working container from an existing image, Buildah defaults to appending '-working-container' to the image's name to construct a name for the container. The Buildah CLI conveniently returns the name of the new container. You can take advantage of this by assigning the returned value to a shell varible using standard shell assignment :
+
+    # container=$(buildah from fedora)
+
+It is not required to assign a shell variable. Running `buildah from fedora` is sufficient. It just helps simplify commands later. To see the name of the container that we stored in the shell variable:
+
+    # echo $container
+
+What can we do with this new container? Let's try running bash:
+
+    # buildah run $container bash
+    
+Notice we get a new shell prompt because we are running a bash shell inside of the container. It should be noted that `buildah run` is primarily intended for helping debug during the build process. A runtime like runc or a container interface like [CRI-O](https://github.com/kubernetes-incubator/cri-o) is more suited for starting containers in production.
+
+Be sure to `exit` out of the container and let's try running something else:
+
+    # buildah run $container java
+
+Oops. Java is not installed. A message containing something like the following was returned.
+
+    container_linux.go:274: starting container process caused "exec: \"java\": executable file not found in $PATH"
+    
+Lets try installing it using:
+    
+    # buildah run $container -- dnf -y install java
+
+The `--` syntax basically tells Buildah: there are no more `buildah run` command options after this point. The options after this point are for inside the containers shell. It is required if the command we specify includes command line options which are not meant for Buildah. 
+
+Now running `buildah run $container java` will show that Java has been installed. It will return the standard Java `Usage` output.
+
+## Building a container from scratch
+
+One of the advantages of using `buildah` to build OCI compliant container images is that you can easily build a container image from scratch and therefore exclude unnecessary packages from your image. E.g. most final container images for production probably don't need a package manager like `dnf`. 
+
+Let's build a container from scratch. The special "image" name "scratch" tells Buildah to create an empty container.  The container has a small amount of metadata about the container but no real Linux content. 
+
+    # newcontainer=$(buildah from scratch)
+  
+You can see this new empty container by running:
+
+    # buildah containers
+  
+You should see output similar to the following:
+
+    CONTAINER ID  BUILDER  IMAGE ID     IMAGE NAME                       CONTAINER NAME
+    82af3b9a9488     *     3d85fcda5754 docker.io/library/fedora:latest  fedora-working-container
+    ac8fa6be0f0a     *                  scratch                          working-container
+
+Its container name is working-container by default and it's stored in the `$newcontainer` variable. Notice the image name (IMAGE NAME) is "scratch". This just indicates that there is no real image yet. i.e. It is containers/storage but there is no representation in containers/image. So when we run:
+
+    # buildah images
+  
+We don't see the image listed. There is no corresponding scratch image. It is an empty container.
+
+So does this container actually do anything? Let's see.
+
+    # buildah run $newcontainer bash
+    
+Nope. This really is empty. The package installer `dnf` is not even inside this container. It's essentially an empty layer on top of the kernel. So what can be done with that?  Thankfully there is a `buildah mount` command.
+
+    # scratchmnt=$(buildah mount $newcontainer)
+    
+By echoing `$scratchmnt` we can see the path for the [overlay image](https://wiki.archlinux.org/index.php/Overlay_filesystem), which gives you a link directly to the root file system of the container.
+
+    # echo $scratchmnt
+    /var/lib/containers/storage/overlay/b78d0e11957d15b5d1fe776293bd40a36c28825fb6cf76f407b4d0a95b2a200d/diff  
+    
+Notice that the overlay image is under `/var/lib/containers/storage` as one would expect. (See above on `containers/storage` or for more information see [containers/storage](https://github.com/containers/storage).) 
+
+Now that we have a new empty container we can install or remove software packages or simply copy content into that container. So let's install `bash` and `coreutils` so that we can run bash scripts. This could easily be `nginx` or other packages needed for your container.
+
+    # dnf install --installroot $scratchmnt --release 26 bash coreutils --setopt install_weak_deps=false -y
+
+Let's try it out (showing the prompt in this example to demonstrate the difference):
+
+    # buildah run $newcontainer bash
+    bash-4.4# cd /usr/bin
+    bash-4.4# ls
+    bash-4.4# exit
+
+Notice we have a `/usr/bin` directory in the newcontainer's image layer. Let's first copy a simple file from our host into the container. Create a file called runecho.sh which contains the following:
+
+    #!/bin/bash
+    for i in `seq 0 9`;
+    do
+    	echo "This is a new container from ipbabble [" $i "]"
+    done
+
+Change the permissions on the file so that it can be run:
+
+    # chmod +x runecho.sh
+    
+With `buildah` files can be copied into the new image and we can also configure the image to run commands. Let's copy this new command into the container's `/usr/bin` directory and configure the container to run the command when the container is run: 
+
+    # buildah copy $newcontainer ./runecho.sh /usr/bin
+    # buildah config --cmd /usr/bin/runecho.sh $newcontainer
+    
+Now run the container:
+
+    # buildah run $newcontainer
+    This is a new container from ipbabble [ 0 ]
+    This is a new container from ipbabble [ 1 ]
+    This is a new container from ipbabble [ 2 ]
+    This is a new container from ipbabble [ 3 ]
+    This is a new container from ipbabble [ 4 ]
+    This is a new container from ipbabble [ 5 ]
+    This is a new container from ipbabble [ 6 ]
+    This is a new container from ipbabble [ 7 ]
+    This is a new container from ipbabble [ 8 ]
+    This is a new container from ipbabble [ 9 ]
+
+It works! Congratulations, you have built a new OCI container from scratch that uses bash scripting. Let's add some more configuration information.
+
+    # buildah config --created-by "ipbabble"  $newcontainer
+    # buildah config --author "wgh at redhat.com @ipbabble" --label name=fedora26-bashecho $newcontainer
+ 
+We can inspect the container's metadata using the `inspect` command:
+ 
+    # buildah inspect $newcontainer
+
+We should probably unmount and commit the image:
+
+     # buildah unmount $newcontainer
+     # buildah commit $newcontainer fedora-bashecho
+     # buildah images
+     
+And you can see there is a new image called `fedora-bashecho:latest`. You can inspect the new image using:
+
+    # buildah inspect --type=image fedora-bashecho
+
+Later when you want to create a new container or containers from this image, you simply need need to do `buildah from fedora-bashecho`. This will create a new containers based on this image for you. 
+
+Now that you have the new image you can remove the scratch container called working-container:
+
+    # buildah rm $newcontainer
+
+or
+
+    # buildah rm working-container
+
+## OCI images built using Buildah are portable
+
+Let's test if this new OCI image is really portable to another OCI technology like Docker. First you should install Docker and start it. Notice that Docker requires a daemon process (that's quite big) in order to run any client commands. Buildah has no daemon requirement.
+
+    # dnf -y install docker
+    # systemctl start docker
+    
+Let's copy that image from where containers/storage stores it to where the Docker daemon stores its images, so that we can run it using Docker. We can achieve this using `buildah push`. This copies the image to Docker's repository area which is located under `/var/lib/docker`. Docker's repository is managed by the Docker daemon. This needs to be explicitly stated by telling Buildah to push to the Docker repository protocol using `docker-daemon:`.
+
+    # buildah push fedora-bashecho docker-daemon:fedora-bashecho:latest
+
+Under the covers, the containers/image library calls into the containers/storage library to read the image's contents, and sends them to the local Docker daemon. This can take a little while. And usually you won't need to do this. If you're using `buildah` you are probably not using Docker. This is just for demo purposes. Let's try it:
+
+    # docker run fedora-bashecho 
+    This is a new container from ipbabble [ 0 ]
+    This is a new container from ipbabble [ 1 ]
+    This is a new container from ipbabble [ 2 ]
+    This is a new container from ipbabble [ 3 ]
+    This is a new container from ipbabble [ 4 ]
+    This is a new container from ipbabble [ 5 ]
+    This is a new container from ipbabble [ 6 ]
+    This is a new container from ipbabble [ 7 ]
+    This is a new container from ipbabble [ 8 ]
+    This is a new container from ipbabble [ 9 ]
+    
+OCI container images built with `buildah` are completely standard as expected. So now it might be time to run:
+
+    # dnf -y remove docker
+
+## Using Dockerfiles with Buildah
+
+What if you have been using Docker for a while and have some existing Dockerfiles. Not a problem. Buildah can build images using a Dockerfile. The `build-using-dockerfile`, or `bud` for short, takes a Dockerfile as input and produces an OCI image.
+
+Find one of your Dockerfiles or create a file called Dockerfile. Use the following example or some variation if you'd like:
+
+    # Base on the Fedora
+    FROM fedora:latest
+    MAINTAINER  ipbabble email buildahboy@redhat.com # not a real email
+
+    # Update image and install httpd
+    RUN echo "Updating all fedora packages"; dnf -y update; dnf -y clean all
+    RUN echo "Installing httpd"; dnf -y install httpd
+ 
+    # Expose the default httpd port 80
+    EXPOSE 80
+
+    # Run the httpd
+    CMD ["/usr/sbin/httpd", "-DFOREGROUND"]
+
+Now run `buildah bud` with the name of the Dockerfile and the name to be given to the created image (e.g. fedora-httpd):
+
+    # buildah bud -f Dockerfile -t fedora-httpd
+
+or, because `buildah bud` defaults to Dockerfile (note the period at the end of the example):
+
+    # buildah bud -t fedora-httpd .
+
+You will see all the steps of the Dockerfile executing. Afterwards `buildah images` will show you the new image. Now we need to create the container using `buildah from` and test it with `buildah run`:
+
+    # httpcontainer=$(buildah from fedora-httpd)
+    # buildah run $httpcontainer
+    
+While that container is running, in another shell run:
+
+    # curl localhost
+    
+You will see the standard Apache webpage.
+
+Why not try and modify the Dockerfile. Do not install httpd, but instead ADD the runecho.sh file and have it run as the CMD. 
+
+## Congratulations
+
+Well done. You have learned a lot about Buildah using this short tutorial. Hopefully you followed along with the examples and found them to be sufficient. Be sure to look at Buildah's man pages to see the other useful commands you can use. Have fun playing.

+# Buildah Tutorial 2
+## Using Buildah with container registries
+
+The purpose of this tutorial is to demonstrate how Buildah can be used to move OCI compliant images in and out of private or public registries. 
+
+In the [first tutorial](https://github.com/projectatomic/buildah/blob/master/docs/tutorials/01-intro.md) we built an image from scratch that we called `fedora-bashecho` and we pushed it to a local Docker repository using the `docker-daemon` protocol. We are going to use the same image to push to a private Docker registry.
+
+First we must pull down a registry. As a shortcut we will save the container name that is returned from the `buildah from` command, into a bash variable called `registry`. This is just like we did in Tutorial 1:
+
+    # registry=$(buildah from registry)
+
+It is worth pointing out that the `from` command can also use other protocols beyond the default (and implicity assumed) order that first looks in local containers-storage (containers-storage:) and then looks in the Docker hub (docker:). For example, if you already had a registry container image in a local Docker registry then you could use the following:
+
+    # registry=$(buildah from docker-daemon:registry:latest)
+
+Then we need to start the registry. You should start the registry in a separate shell and leave it running there:
+
+    # buildah run $registry
+    
+If you would like to see more details as to what is going on inside the registry, especially if you are having problems with the registry, you can run the registry container in debug mode as follows:
+
+    # buildah --debug run $registry
+
+You can use `--debug` on any Buildah command. 
+
+The registry is running and is waiting for requests to process. Notice that this registry is a Docker registry that we pulled from Docker hub and we are running it for this example using `buildah run`. There is no Docker daemon running at this time.
+
+Let's push our image to the private registry. By default, Buildah is set up to expect secure connections to a registry. Therefore we will need to turn the TLS verification off using the `--tls-verify` flag. We also need to tell Buildah that the registry is on this local host ( i.e. localhost) and listening on port 5000. Similar to  what you'd expect to do on multi-tenant Docker hub, we will explicitly specify that the registry is to store the image under the `ipbabble` repository - so as not to clash with other users' similarly named images.
+
+    # buildah push --tls-verify=false fedora-bashecho docker://localhost:5000/ipbabble/fedora-bashecho:latest
+
+[Skopeo](https://github.com/projectatomic/skopeo) is a ProjectAtomic tool that was created to inspect images in registries without having to pull the image from the registry. It has grown to have many other uses. We will verify that the image has been stored by using Skopeo to inspect the image in the registry:
+ 
+    # skopeo inspect --tls-verify=false docker://localhost:5000/ipbabble/fedora-bashecho:latest
+    {
+        "Name": "localhost:5000/ipbabble/fedora-bashecho",
+        "Digest": "sha256:6806f9385f97bc09f54b5c0ef583e58c3bc906c8c0b3e693d8782d0a0acf2137",
+        "RepoTags": [
+            "latest"
+        ],
+        "Created": "2017-12-05T21:38:12.311901938Z",
+        "DockerVersion": "",
+        "Labels": {
+            "name": "fedora-bashecho"
+        },
+        "Architecture": "amd64",
+        "Os": "linux",
+        "Layers": [
+            "sha256:0cb7556c714767b8da6e0299cbeab765abaddede84769475c023785ae66d10ca"
+        ]
+    }
+
+We can verify that it is still portable with Docker by starting Docker again, as we did in the first tutorial. Then we can pull down the image and starting the container using Docker:
+
+    # systemctl start docker
+    # docker pull localhost:5000/ipbabble/fedora-bashecho
+    Using default tag: latest
+    Trying to pull repository localhost:5000/ipbabble/fedora-bashecho ... 
+    sha256:6806f9385f97bc09f54b5c0ef583e58c3bc906c8c0b3e693d8782d0a0acf2137: Pulling from localhost:5000/ipbabble/fedora-bashecho
+    0cb7556c7147: Pull complete 
+    Digest: sha256:6806f9385f97bc09f54b5c0ef583e58c3bc906c8c0b3e693d8782d0a0acf2137
+    Status: Downloaded newer image for localhost:5000/ipbabble/fedora-bashecho:latest
+
+    # docker run localhost:5000/ipbabble/fedora-bashecho
+    This is a new container named ipbabble [ 0 ]
+    This is a new container named ipbabble [ 1 ]
+    This is a new container named ipbabble [ 2 ]
+    This is a new container named ipbabble [ 3 ]
+    This is a new container named ipbabble [ 4 ]
+    This is a new container named ipbabble [ 5 ]
+    This is a new container named ipbabble [ 6 ]
+    This is a new container named ipbabble [ 7 ]
+    This is a new container named ipbabble [ 8 ]
+    This is a new container named ipbabble [ 9 ]
+    # systemctl stop docker
+
+Pushing to Docker hub is just as easy. Of course you must have an account with credentials. In this example I'm using a Docker hub API key, which has the form "username:password" (example password has been edited for privacy), that I created with my Docker hub account. I use the `--creds` flag to use my API key. I also specify my local image name `fedora-bashecho` as my image source and I use the `docker` protocol with no host or port so that it will look at the default Docker hub registry:
+
+    #  buildah push --creds ipbabble:5bbb9990-6eeb-1234-af1a-aaa80066887c fedora-bashecho docker://ipbabble/fedora-bashecho:latest
+
+And let's inspect that with Skopeo:
+
+    # skopeo inspect --creds ipbabble:5bbb9990-6eeb-1234-af1a-aaa80066887c docker://ipbabble/fedora-bashecho:latest
+    {
+        "Name": "docker.io/ipbabble/fedora-bashecho",
+        "Digest": "sha256:6806f9385f97bc09f54b5c0ef583e58c3bc906c8c0b3e693d8782d0a0acf2137",
+        "RepoTags": [
+            "latest"
+        ],
+        "Created": "2017-12-05T21:38:12.311901938Z",
+        "DockerVersion": "",
+        "Labels": {
+            "name": "fedora-bashecho"
+        },
+        "Architecture": "amd64",
+        "Os": "linux",
+        "Layers": [
+            "sha256:0cb7556c714767b8da6e0299cbeab765abaddede84769475c023785ae66d10ca"
+        ]
+    }
+
+We can use Buildah to pull down the image using the `buildah from` command. But before we do let's clean up our local containers-storage so that we don't have an existing fedora-bashecho - otherwise Buildah will know it already exists and not bother pulling it down.
+
+    #  buildah images 
+    IMAGE ID             IMAGE NAME                                               CREATED AT             SIZE

+    IMAGE ID             IMAGE NAME                                               CREATED AT             SIZE

+
+Okay, so we don't have a fedora-bashecho anymore. Let's pull the image from Docker hub:
+
+    # buildah from ipbabble/fedora-bashecho 
+
+If you don't want to bother doing the remove image step (`rmi`) you can use the flag `--pull-always` to force the image to be pulled again and overwrite any corresponding local image.
+
+Now check that image is in the local containers-storage:
+
+    # buildah images
+    IMAGE ID             IMAGE NAME                                               CREATED AT             SIZE
+    d4cd7d73ee42         docker.io/library/registry:latest                        Dec 1, 2017 22:15      31.74 MB
+    864871ac1c45         docker.io/ipbabble/fedora-bashecho:latest                Dec 5, 2017 21:38      315.4 MB
+

+# Installation Instructions
+
+## System Requirements
+
+### Kernel Version Requirements
+To run Buildah on Red Hat Enterprise Linux or CentOS, version 7.4 or higher is required.
+On other Linux distributions Buildah requires a kernel version of 4.0 or
+higher in order to support the OverlayFS filesystem.  The kernel version can be checked
+with the 'uname -a' command.
+
+### runc Requirement
+
+Buildah uses `runc` to run commands when `buildah run` is used, or when `buildah build-using-dockerfile`
+encounters a `RUN` instruction, so you'll also need to build and install a compatible version of
+[runc](https://github.com/opencontainers/runc) for Buildah to call for those cases.  If Buildah is installed
+via a package manager such as yum, dnf or apt-get, runc will be installed as part of that process.
+
+## Package Installation
+
+Buildah is available on several software repositories and can be installed via a package manager such
+as yum, dnf or apt-get on a number of Linux distributions.
+
+## Installation from GitHub
+
+Prior to installing Buildah, install the following packages on your Linux distro:
+* make
+* golang (Requires version 1.8.1 or higher.)
+* bats
+* btrfs-progs-devel
+* bzip2
+* device-mapper-devel
+* git
+* go-md2man
+* gpgme-devel
+* glib2-devel
+* libassuan-devel
+* ostree-devel
+* runc (Requires version 1.0 RC4 or higher.)
+* skopeo-containers
+
+### Fedora
+
+In Fedora, you can use this command:
+
+```
+ dnf -y install \
+    make \
+    golang \
+    bats \
+    btrfs-progs-devel \
+    device-mapper-devel \
+    glib2-devel \
+    gpgme-devel \
+    libassuan-devel \
+    ostree-devel \
+    git \
+    bzip2 \
+    go-md2man \
+    runc \
+    skopeo-containers
+```
+
+Then to install Buildah on Fedora follow the steps in this example:
+
+
+```
+  mkdir ~/buildah
+  cd ~/buildah
+  export GOPATH=`pwd`
+  git clone https://github.com/projectatomic/buildah ./src/github.com/projectatomic/buildah
+  cd ./src/github.com/projectatomic/buildah
+  make
+  sudo make install
+  buildah --help
+```
+
+### RHEL, CentOS
+
+In RHEL and CentOS 7, ensure that you are subscribed to `rhel-7-server-rpms`,
+`rhel-7-server-extras-rpms`, and `rhel-7-server-optional-rpms`, then
+run this command:
+
+```
+ yum -y install \
+    make \
+    golang \
+    bats \
+    btrfs-progs-devel \
+    device-mapper-devel \
+    glib2-devel \
+    gpgme-devel \
+    libassuan-devel \
+    ostree-devel \
+    git \
+    bzip2 \
+    go-md2man \
+    runc \
+    skopeo-containers
+```
+
+The build steps for Buildah on RHEL or CentOS are the same as Fedora, above.
+
+### Ubuntu
+
+In Ubuntu zesty and xenial, you can use these commands:
+
+```
+  apt-get -y install software-properties-common
+  add-apt-repository -y ppa:alexlarsson/flatpak
+  add-apt-repository -y ppa:gophers/archive
+  apt-add-repository -y ppa:projectatomic/ppa
+  apt-get -y -qq update
+  apt-get -y install bats btrfs-tools git libapparmor-dev libdevmapper-dev libglib2.0-dev libgpgme11-dev libostree-dev libseccomp-dev libselinux1-dev skopeo-containers go-md2man
+  apt-get -y install golang-1.8
+```
+Then to install Buildah on Ubuntu follow the steps in this example:
+
+```
+  mkdir ~/buildah
+  cd ~/buildah
+  export GOPATH=`pwd`
+  git clone https://github.com/projectatomic/buildah ./src/github.com/projectatomic/buildah
+  cd ./src/github.com/projectatomic/buildah
+  PATH=/usr/lib/go-1.8/bin:$PATH make runc all TAGS="apparmor seccomp"
+  sudo make install install.runc
+  buildah --help
+```
+
+### Debian
+
+To install the required dependencies, you can use those commands, tested under Debian GNU/Linux amd64 9.3 (stretch):
+
+```
+gpg --recv-keys 0x018BA5AD9DF57A4448F0E6CF8BECF1637AD8C79D
+gpg --export 0x018BA5AD9DF57A4448F0E6CF8BECF1637AD8C79D >> /usr/share/keyrings/projectatomic-ppa.gpg
+echo 'deb [signed-by=/usr/share/keyrings/projectatomic-ppa.gpg] http://ppa.launchpad.net/projectatomic/ppa/ubuntu zesty main' > /etc/apt/sources.list.d/projectatomic-ppa.list
+apt update
+apt -y install -t stretch-backports libostree-dev golang
+apt -y install bats btrfs-tools git libapparmor-dev libdevmapper-dev libglib2.0-dev libgpgme11-dev libseccomp-dev libselinux1-dev skopeo-containers go-md2man
+``` 
+
+The build steps on Debian are otherwise the same as Ubuntu, above.
