 When packages are cached, for iterating locally it's particularly useful to jump straight to the image that you want to build. You can use ```--only-target-package``` to jump directly to the image you are interested in. Luet will take care of checking if the images are present in the remote registry, and would build them if any of those are missing.
 
+## Building for a different platform
+
+Sometimes you need to build a package for a different platform than the one running on your host machine. For example, you may want to build an arm64 package, but your machine is x86. To do this, all you need to do is pass the following arguments:
+
+```
+luet --backend-args --load --backend-args --platform --backend-args linux/arm64 build PACKAGE_NAME
+```
+
 ## Notes
 
 - All the files which are next to a `build.yaml` are copied in the container which is running your build, so they are always accessible during build time.

+    Configuring Luet
+---
+
+### General
+
+```yaml
+general:
+  # Define max concurrency processes. Default is based of arch: runtime.NumCPU()
+  concurrency: 1
+  # Enable Debug. If debug is active spinner is disabled.
+  debug: false
+  # Show output of build execution (docker, img, etc.)
+  show_build_output: false
+  # Define spinner ms
+  spinner_ms: 200
+  # Define spinner charset. See https://github.com/briandowns/spinner
+  spinner_charset: 22
+  # Enable warnings to exit
+  fatal_warnings: false
+  # Try extracting tree/packages with the same ownership as exists in the archive (default for superuser).
+  same_owner: false
+```
+
+### Images
+
+After the building of the packages, you can apply arbitrary images on top using the `images` stanza. This is useful if you need to pin a package to a specific version.
+
+```yaml
+images:
+  - quay.io/kairos/packages:kairos-agent-system-2.1.12
+```
+
+### Logging
+
+```yaml
+logging:
+  # Enable loggging to file (if path is not empty)
+  enable_logfile: false
+  #  Leave empty to skip logging to file.
+  path: "/var/log/luet.log"
+  # Set logging level: error|warning|info|debug
+  level: "info"
+  #  Enable JSON log format instead of console mode.
+  json_format: false.
+  #  Disable/Enable color
+  color: true
+  #  Enable/Disable emoji
+  enable_emoji: true
+```
+
+### Repositories configurations directories.
+
+```yaml
+# Define the list of directories where luet
+# try for files with .yml extension that define
+# luet repository.
+repos_confdir:
+  - /etc/luet/repos.conf.d
+```
+
+### Finalizer Environment Variables
+
+```yaml
+finalizer_envs:
+ - key: "BUILD_ISO"
+   value: "1"
+```
+
+### Repositories
+
+To add repositories, you can either add a `repositories` stanza in your `/etc/luet/luet.yaml` or either add one or more yaml files in `/etc/luet/repos.conf.d/`.
+
+#### Configuring repositories in the main configuration file
+
+```yaml
+logging:
+  color: true # Enable/Disable colored output
+  enable_emoji: true # Enable/Disable emoji from output
+general:
+  debug: false # Enable/Disable debug
+system:
+  rootfs: "/" # What's our rootfs. Luet can install packages outside of "/"
+  database_path: "/var/db/luet" # Where to store DB files
+  database_engine: "boltdb"
+  tmpdir_base: "/var/tmp/luet" # The temporary directory to be used
+repositories:
+- name: "some-repository-name" # Repository name
+  description: "A beautiful description"
+  type: "http" # Repository type, disk or http are supported (disk for local path)
+  enable: true # Enable/Disable repo
+  cached: true # Enable cache for repository
+  priority: 3 # Cache priority
+  urls: # Repository URLs
+    - "...."
+```
+
+#### Using different files to configure repositories
+
+In the main configuration file you can specify the directory where all repositories are configured:
+
+```yaml
+repos_confdir:
+  - /etc/luet/repos.conf.d
+```
+ 
+Then add a file inside `/etc/luet/repos.conf.d/example.yaml` with your configuration, e.g.:
+
+```yaml
+name: "..." # Repository name
+description: "..."
+type: "http" # Repository type, disk or http are supported (disk for local path)
+enable: true # Enable/Disable repo
+cached: true # Enable cache for repository
+priority: 3 # Cache priority
+urls: # Repository URLs
+  - "..."
+```
+
+There is available a [collection of repositories](https://packages.mocaccino.org/repository-index), which is containing a list of repositories that can be installed in the system with `luet install`.
+
+If you installed Luet from the curl command, you just need to run `luet search repository` to see a list of all the available repository, and you can install them singularly by running `luet install repository/<name>`. Otherwise, add the repository stanzas you need to `/etc/luet/luet.yaml`.
+
+#### Config protect configuration files directories.
+
+```yaml
+# Define the list of directories where load
+# configuration files with the list of config
+# protect paths.
+config_protect_confdir:
+  - /etc/luet/config.protect.d
+# Ignore rules defined on
+# config protect confdir and packages
+# annotation.
+config_protect_skip: false
+# The paths used for load repositories and config
+# protects are based on host rootfs.
+# If set to false rootfs path is used as prefix.
+config_from_host: true
+```
+
+### Solver Parameter Configuration
+
+```yaml
+solver:
+  # Solver strategy to solve possible conflicts during depedency
+  # solving. Defaults to empty (none). Available: qlearning
+  type: ""
+  # Solver agent learning rate. 0.1 to 1.0
+  rate: 0.7
+  # Learning discount factor.
+  discount: 1.0
+  # Number of overall attempts that the solver has available before bailing out.
+  max_attempts: 9000
+```
+
+### System
+
+```yaml
+system:
+  # Rootfs path of the luet system. Default is /.
+  # A specific path could be used for test installation to
+  # a chroot environment.
+  rootfs: "/"
+  # Database engine used for luet database.
+  # Supported values: boltdb|memory
+  database_engine: boltdb
+  # Database path directory where store luet database.
+  # The path is appended to rootfs option path.
+  database_path: "/var/cache/luet"
+  # Define the tmpdir base directory where luet store temporary files.
+  # Default $TMPDIR/tmpluet
+  tmpdir_base: "/tmp/tmpluet"
+```

A spec is composed at least by the runtime (`definition.yaml` or a `collection.yaml`) and the buildtime specification (`build.yaml`).
 
 Luet identifies the package definition by looking at directories that contains a `build.yaml` and a `definition.yaml` (or `collection.yaml`) files. A Luet tree is merely a composition of directories that follows this convention. There is no constriction on either folder naming or hierarchy.

-# go-ansiterm
-
-This is a cross platform Ansi Terminal Emulation library.  It reads a stream of Ansi characters and produces the appropriate function calls.  The results of the function calls are platform dependent.
-
-For example the parser might receive "ESC, [, A" as a stream of three characters.  This is the code for Cursor Up (http://www.vt100.net/docs/vt510-rm/CUU).  The parser then calls the cursor up function (CUU()) on an event handler.  The event handler determines what platform specific work must be done to cause the cursor to move up one position.
-
-The parser (parser.go) is a partial implementation of this state machine (http://vt100.net/emu/vt500_parser.png).  There are also two event handler implementations, one for tests (test_event_handler.go) to validate that the expected events are being produced and called, the other is a Windows implementation (winterm/win_event_handler.go).
-
-See parser_test.go for examples exercising the state machine and generating appropriate function calls.

-// IMPORTANT NOTE:
-//
-//	The methods below make extensive use of the "unsafe" package to obtain the required pointers.
-//	Beginning in Go 1.3, the garbage collector may release local variables (e.g., incoming arguments, stack
-//	variables) the pointers reference *before* the API completes.
-//
-//  As a result, in those cases, the code must hint that the variables remain in active by invoking the
-//	dummy method "use" (see below). Newer versions of Go are planned to change the mechanism to no longer
-//	require unsafe pointers.
-//
-//	If you add or modify methods, ENSURE protection of local variables through the "use" builtin to inform
-//	the garbage collector the variables remain in use if:
-//
-//	-- The value is not a pointer (e.g., int32, struct)
-//	-- The value is not referenced by the method after passing the pointer to Windows

+You will only need to do this once across all repos using our CLA.
 
-We also require that contributors sign their commits using git commit -s or git commit --signoff to certify they either authored the work themselves

-attest to the rules listed. Our CI uses the DCO Github app to ensure that all commits in a given PR are signed-off.
+Additionally, the pull request pipeline requires the following steps to be performed before
+mergining.
 
+### Code Sign-Off
+
+We require that contributors sign their commits using [`git commit --signoff`][git-commit-s]
+to certify they either authored the work themselves or otherwise have permission to use it in this project.
+
+A range of commits can be signed off using [`git rebase --signoff`][git-rebase-s].
+
+Please see [the developer certificate](https://developercertificate.org) for more info,
+as well as to make sure that you can attest to the rules listed.
+Our CI uses the DCO Github app to ensure that all commits in a given PR are signed-off.
+
+### Linting
+
+Code must pass a linting stage, which uses [`golangci-lint`][lint].
+The linting settings are stored in [`.golangci.yaml`](./.golangci.yaml), and can be run
+automatically with VSCode by adding the following to your workspace or folder settings:
+
+```json
+    "go.lintTool": "golangci-lint",
+    "go.lintOnSave": "package",
+```
+
+Additional editor [integrations options are also available][lint-ide].
+
+Alternatively, `golangci-lint` can be [installed locally][lint-install] and run from the repo root:
+
+```shell
+# use . or specify a path to only lint a package
+# to show all lint errors, use flags "--max-issues-per-linter=0 --max-same-issues=0"
+> golangci-lint run ./...
+```
+
+### Go Generate
+
+The pipeline checks that auto-generated code, via `go generate`, are up to date.
+
+This can be done for the entire repo:
+
+```shell
+> go generate ./...
+```
