 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.

+---
+
+### General
+
+```yaml

+  # Define max concurrency processes. Default is based of arch: runtime.NumCPU()
+  concurrency: 1
+  # Enable Debug. If debug is active spinner is disabled.
+  debug: false

+  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.

 As Luet allows to express constraints with selectors ( e.g. `A depends on >=B-1.0`) it generates additional constraints to guarantee that at least one package and at most one is picked as dependency (*ALO* and *AMO*).

+Luet [packages](/docs/concepts/packages/) are defined by specfiles. Specfiles define the runtime and builtime requirements of a package.  There is an hard distinction between runtime and buildtime. 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.

+// Package cmp determines equality of values.
+//
+// This package is intended to be a more powerful and safer alternative to
+// reflect.DeepEqual for comparing whether two values are semantically equal.
+// It is intended to only be used in tests, as performance is not a goal and
+// it may panic if it cannot compare the values. Its propensity towards
+// panicking means that its unsuitable for production environments where a
+// spurious panic may be fatal.
+//
+// The primary features of cmp are:
+//
+// • When the default behavior of equality does not suit the needs of the test,
+// custom equality functions can override the equality operation.
+// For example, an equality function may report floats as equal so long as they
+// are within some tolerance of each other.
+//
+// • Types that have an Equal method may use that method to determine equality.
+// This allows package authors to determine the equality operation for the types
+// that they define.
+//
+// • If no custom equality functions are used and no Equal method is defined,
+// equality is determined by recursively comparing the primitive kinds on both
+// values, much like reflect.DeepEqual. Unlike reflect.DeepEqual, unexported
+// fields are not compared by default; they result in panics unless suppressed
+// by using an Ignore option (see cmpopts.IgnoreUnexported) or explicitly
+// compared using the Exporter option.

+// Equal reports whether x and y are equal by recursively applying the
+// following rules in the given order to x and y and all of their sub-values:
+//
+// • Let S be the set of all Ignore, Transformer, and Comparer options that
+// remain after applying all path filters, value filters, and type filters.
+// If at least one Ignore exists in S, then the comparison is ignored.
+// If the number of Transformer and Comparer options in S is greater than one,
+// then Equal panics because it is ambiguous which option to use.
+// If S contains a single Transformer, then use that to transform the current
+// values and recursively call Equal on the output values.
+// If S contains a single Comparer, then use that to compare the current values.
+// Otherwise, evaluation proceeds to the next rule.
+//
+// • If the values have an Equal method of the form "(T) Equal(T) bool" or
+// "(T) Equal(I) bool" where T is assignable to I, then use the result of
+// x.Equal(y) even if x or y is nil. Otherwise, no such method exists and
+// evaluation proceeds to the next rule.
+//
+// • Lastly, try to compare x and y based on their basic kinds.
+// Simple kinds like booleans, integers, floats, complex numbers, strings, and
+// channels are compared using the equivalent of the == operator in Go.
+// Functions are only equal if they are both nil, otherwise they are unequal.
+//
+// Structs are equal if recursively calling Equal on all fields report equal.
+// If a struct contains unexported fields, Equal panics unless an Ignore option
+// (e.g., cmpopts.IgnoreUnexported) ignores that field or the Exporter option
+// explicitly permits comparing the unexported field.
+//
+// Slices are equal if they are both nil or both non-nil, where recursively
+// calling Equal on all non-ignored slice or array elements report equal.
+// Empty non-nil slices and nil slices are not equal; to equate empty slices,
+// consider using cmpopts.EquateEmpty.
+//
+// Maps are equal if they are both nil or both non-nil, where recursively
+// calling Equal on all non-ignored map entries report equal.
+// Map keys are equal according to the == operator.
+// To use custom comparisons for map keys, consider using cmpopts.SortMaps.
+// Empty non-nil maps and nil maps are not equal; to equate empty maps,
+// consider using cmpopts.EquateEmpty.
+//
+// Pointers and interfaces are equal if they are both nil or both non-nil,
+// where they have the same underlying concrete type and recursively
+// calling Equal on the underlying values reports equal.
+//
+// Before recursing into a pointer, slice element, or map, the current path
+// is checked to detect whether the address has already been visited.
+// If there is a cycle, then the pointed at values are considered equal
+// only if both addresses were previously visited in the same path step.

+	//	a search that starts at the beginning (the top-left corner), and
+	//	a search that starts at the end (the bottom-right corner). The goal of
+	//	the search is connect with the search from the opposite corner.
+	//	• As we search, we build a path in a greedy manner, where the first
+	//	match seen is added to the path (this is sub-optimal, but provides a
+	//	decent result in practice). When matches are found, we try the next pair
+	//	of symbols in the lists and follow all matches as far as possible.
+	//	• When searching for matches, we search along a diagonal going through
+	//	through the "frontier" point. If no matches are found, we advance the
+	//	frontier towards the opposite corner.
+	//	• This algorithm terminates when either the X coordinates or the
+	//	Y coordinates of the forward and reverse frontier points ever intersect.
+
+	// This algorithm is correct even if searching only in the forward direction
+	// or in the reverse direction. We do both because it is commonly observed
+	// that two lists commonly differ because elements were added to the front
+	// or end of the other list.
