 ### Dependencies management
 
-Make sure [`vndr`](https://github.com/LK4D4/vndr) is installed.
+Dependencies are managed via [standard go modules](https://golang.org/ref/mod).
 
 In order to add a new dependency to this project:
 
-- add a new line to `vendor.conf` according to `vndr` rules (e.g. `github.com/pkg/errors master`)
+- use `go get -d path/to/dep@version` to add a new line to `go.mod`
 - run `make vendor`
 
 In order to update an existing dependency:
 
-- update the relevant dependency line in `vendor.conf`
+- use `go get -d -u path/to/dep@version` to update the relevant dependency line in `go.mod`
 - run `make vendor`
 
 When new PRs for [containers/image](https://github.com/containers/image) break `skopeo` (i.e. `containers/image` tests fail in `make test-skopeo`):
 
 - create out a new branch in your `skopeo` checkout and switch to it
-- update `vendor.conf`. Find out the `containers/image` dependency; update it to vendor from your own branch and your own repository fork (e.g. `github.com/containers/image my-branch https://github.com/runcom/image`)
+- find out the version of `containers/image` you want to use and note its commit ID. You might also want to use a fork of `containers/image`, in that case note its repo
+- use `go get -d github.com/$REPO/image/v5@$COMMIT_ID` to download the right version. The command will fetch the dependency and then fail because of a conflict in `go.mod`, this is expected. Note the pseudo-version (eg. `v5.13.1-0.20210707123201-50afbf0a326`)
+- use `go mod edit -replace=github.com/containers/image/v5=github.com/$REPO/image/v5@$PSEUDO_VERSION` to add a replacement line to `go.mod` (e.g. `replace github.com/containers/image/v5 => github.com/moio/image/v5 v5.13.1-0.20210707123201-50afbf0a3262`)
 - run `make vendor`
 - make any other necessary changes in the skopeo repo (e.g. add other dependencies now required by `containers/image`, or update skopeo for changed `containers/image` API)
 - optionally add new integration tests to the skopeo repo
 - submit the resulting branch as a skopeo PR, marked “DO NOT MERGE”
 - iterate until tests pass and the PR is reviewed
 - then the original `containers/image` PR can be merged, disregarding its `make test-skopeo` failure
-- as soon as possible after that, in the skopeo PR, restore the `containers/image` line in `vendor.conf` to use `containers/image:master`
+- as soon as possible after that, in the skopeo PR, use `go mod edit -dropreplace=github.com/containers/image` to remove the `replace` line in `go.mod`
 - run `make vendor`
 - update the skopeo PR with the result, drop the “DO NOT MERGE” marking
 - after tests complete successfully again, merge the skopeo PR

+This directory contains the Dockerfiles necessary to create the skopeoimage container
+images that are housed on quay.io under the skopeo account.  All repositories where
+the images live are public and can be pulled without credentials.  These container images are secured and the
+resulting containers can run safely with privileges within the container.
 
-  * quay.io/skopeo/stable - This image is built using the latest stable version of Skopeo in a Fedora based container.  Built with skopeoimage/stable/Dockerfile.
-  * quay.io/skopeo/upstream - This image is built using the latest code found in this GitHub repository.  When someone creates a commit and pushes it, the image is created.  Due to that the image changes frequently and is not guaranteed to be stable.  Built with skopeoimage/upstream/Dockerfile.
-  * quay.io/skopeo/testing - This image is built using the latest version of Skopeo that is or was in updates testing for Fedora.  At times this may be the same as the stable image.  This container image will primarily be used by the development teams for verification testing when a new package is created.  Built with skopeoimage/testing/Dockerfile.
+The container images are built using the latest Fedora and then Skopeo is installed into them.
+The PATH in the container images is set to the default PATH provided by Fedora.  Also, the
+ENTRYPOINT and the WORKDIR variables are not set within these container images, as such they
+default to `/`.
 
-## Multiarch images
+The container images are:
 
-Multiarch images are available for Skopeo upstream and stable versions. Supported architectures are `amd64`, `s390x`, `ppc64le`.
-Available images are `quay.io/skopeo/upstream:master`, `quay.io/skopeo/stable:v1.2.0`, `quay.io/containers/skopeo:v1.2.0`.
+  * `quay.io/containers/skopeo:<version>` and `quay.io/skopeo/stable:<version>` -
+    These images are built when a new Skopeo version becomes available in
+    Fedora.  These images are intended to be unchanging and stable, they will
+    never be updated by automation once they've been pushed.  For build details,
+    please [see the configuration file](stable/Dockerfile).
+  * `quay.io/containers/skopeo:latest` and `quay.io/skopeo/stable:latest` -
+    Built daily using the same Dockerfile as above.  The skopeo version
+    will remain the "latest" available in Fedora, however the image
+    contents may vary compared to the version-tagged images.
+  * `quay.io/skopeo/testing:latest` - This image is built daily, using the
+    latest version of Skopeo that was in the Fedora `updates-testing` repository.
+    The image is Built with [the testing Dockerfile](testing/Dockerfile).
+  * `quay.io/skopeo/upstream:latest` - This image is built daily using the latest
+    code found in this GitHub repository.  Due to the image changing frequently,
+    it's not guaranteed to be stable or even executable.  The image is built with
+    [the upstream Dockerfile](upstream/Dockerfile).
 
-Images can be used the same way as in a single architecture case, no extra setup is required. For samples see next chapter.

-# skopeo container image build with Travis
-
-This document describes the details and requirements to build and publish skopeo container images. The images are published as several architecture specific images and multiarch images on top for upstream and stable versions.
-
-The Travis configuration is available at `.travis.yml`.
-
-The code to build and publish images is available at `release/Makefile` and should be used only via Travis.
-
-Travis workflow has 3 major pieces:
-- `local-build` - build and test source code locally on osx and linux/amd64 environments, 2 jobs are running in parallel
-- `image-build-push` - build and push container images with several Travis jobs running in parallel to build images for several architectures (linux/amd64, linux/s390x, linux/ppc64le). Build part is done for each PR, push part is executed only in case of cron job or master branch update.
-- `manifest-multiarch-push` - create and push image manifests, which consists of architecture specific images from previous step. Executed only in case of cron job or master branch update.
-
-## Ways to have full workflow run
-- [cron job](https://docs.travis-ci.com/user/cron-jobs/#adding-cron-jobs)
-- Trigger build from Travis CI
-- Update code in master branch
-
-## Environment variables
-
-Several environment variables are used to customize image names and keep private credentials to push to quay.io repositories.
-
-**Image tags** are specified in environment variable and should be manually updated in case of new release.
-
-- `SKOPEO_QUAY_USERNAME` and `SKOPEO_QUAY_PASSWORD` are credentials to push images to `quay.io/skopeo/stable` and `quay.io/skopeo/upstream` repos, and require the credentials to have write permissions. These variables should be specified in [Travis](https://docs.travis-ci.com/user/environment-variables/#defining-variables-in-repository-settings).
-- `CONTAINERS_QUAY_USERNAME` and `CONTAINERS_QUAY_PASSWORD` are credentials to push images to `quay.io/containers/skopeo` repos, and require the credentials to have write permissions. These variables should be specified in [Travis](https://docs.travis-ci.com/user/environment-variables/#defining-variables-in-repository-settings).
-
-Variables in .travis.yml
-- `MULTIARCH_MANIFEST_ARCHITECTURES` is a list with architecture shortnames, to appear in final multiarch manifest. The values should fit to architectures used in the `image-build-push` Travis step.
-- `STABLE_IMAGE`, `EXTRA_STABLE_IMAGE` are image names to publish stable Skopeo.
-- `UPSTREAM_IMAGE` is an image name to publish upstream Skopeo.

-Testing
-
-There are two important types of tests used for this package. The first is
-contained inside '*_test.go' files and uses the standard Go unit testing
-framework. These tests are primarily devoted to holistically testing the
-decoder and encoder.
-
-The second type of testing is used to verify the implementation's adherence
-to the TOML specification. These tests have been factored into their own
-project: https://github.com/BurntSushi/toml-test
-
-The reason the tests are in a separate project is so that they can be used by
-any implementation of TOML. Namely, it is language agnostic.
+The github.com/BurntSushi/toml/cmd/tomlv package implements a TOML validator,
+and can be used to verify if TOML document is valid. It can also be used to
