 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.

+  # 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

+  #  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

-# 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
-//
-//	See http://golang.org/doc/go1.3.

-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.

-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.

-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-
-GoUtils provides users with utility functions to manipulate strings in various ways. It is a Go implementation of some
-string manipulation libraries of Java Apache Commons. GoUtils includes the following Java Apache Commons classes:
-* WordUtils    
-* RandomStringUtils  
-* StringUtils (partial implementation)
-
-## Installation
-If you have Go set up on your system, from the GOPATH directory within the command line/terminal, enter this:
-
-	go get github.com/Masterminds/goutils
-
-If you do not have Go set up on your system, please follow the [Go installation directions from the documenation](http://golang.org/doc/install), and then follow the instructions above to install GoUtils.
-
-
-## Documentation
-GoUtils doc is available here: [![GoDoc](https://godoc.org/github.com/Masterminds/goutils?status.png)](https://godoc.org/github.com/Masterminds/goutils)
-
-
-## Usage
-The code snippets below show examples of how to use GoUtils. Some functions return errors while others do not. The first instance below, which does not return an error, is the `Initials` function (located within the `wordutils.go` file).
-
-    package main
-
-    import (
-        "fmt"
-    	"github.com/Masterminds/goutils"
-    )
-
-    func main() {
-
-    	// EXAMPLE 1: A goutils function which returns no errors
-        fmt.Println (goutils.Initials("John Doe Foo")) // Prints out "JDF"
-
-    }
-Some functions return errors mainly due to illegal arguements used as parameters. The code example below illustrates how to deal with function that returns an error. In this instance, the function is the `Random` function (located within the `randomstringutils.go` file).
-
-    package main
-
-    import (
-        "fmt"
-        "github.com/Masterminds/goutils"
-    )
-
-    func main() {
-
-        // EXAMPLE 2: A goutils function which returns an error
-        rand1, err1 := goutils.Random (-1, 0, 0, true, true)  
-
-        if err1 != nil {
-			fmt.Println(err1) // Prints out error message because -1 was entered as the first parameter in goutils.Random(...)
-		} else {
-			fmt.Println(rand1)
-		}
-
-    }
-

-
-## 3.0.1 (2019-09-13)
-
-### Fixed
-
-- #125: Fixes issue with module path for v3
-
-## 3.0.0 (2019-09-12)
-
-This is a major release of the semver package which includes API changes. The Go
-API is compatible with ^1. The Go API was not changed because many people are using
-`go get` without Go modules for their applications and API breaking changes cause
-errors which we have or would need to support.
-
-The changes in this release are the handling based on the data passed into the
-functions. These are described in the added and changed sections below.
-
-### Added
-
-- StrictNewVersion function. This is similar to NewVersion but will return an
-  error if the version passed in is not a strict semantic version. For example,
-  1.2.3 would pass but v1.2.3 or 1.2 would fail because they are not strictly
-  speaking semantic versions. This function is faster, performs fewer operations,
-  and uses fewer allocations than NewVersion.
-- Fuzzing has been performed on NewVersion, StrictNewVersion, and NewConstraint.
-  The Makefile contains the operations used. For more information on you can start
-  on Wikipedia at https://en.wikipedia.org/wiki/Fuzzing
-- Now using Go modules
-
-### Changed
-
-- NewVersion has proper prerelease and metadata validation with error messages
-  to signal an issue with either of them
-- ^ now operates using a similar set of rules to npm/js and Rust/Cargo. If the
-  version is >=1 the ^ ranges works the same as v1. For major versions of 0 the
-  rules have changed. The minor version is treated as the stable version unless
-  a patch is specified and then it is equivalent to =. One difference from npm/js
-  is that prereleases there are only to a specific version (e.g. 1.2.3).
-  Prereleases here look over multiple versions and follow semantic version
-  ordering rules. This pattern now follows along with the expected and requested
-  handling of this packaged by numerous users.
-
-## 1.5.0 (2019-09-11)
-
-### Added
-
-- #103: Add basic fuzzing for `NewVersion()` (thanks @jesse-c)
-
-### Changed

-### Fixed
-
-- Issue #21: Per the SemVer spec (section 9) a pre-release is unstable and
-  might not satisfy the intended compatibility. The change here ignores pre-releases
-  on constraint checks (e.g., ~ or ^) when a pre-release is not part of the

-# SemVer
-
-The `semver` package provides the ability to work with [Semantic Versions](http://semver.org) in Go. Specifically it provides the ability to:
-
-* Parse semantic versions
-* Sort semantic versions
-* Check if a semantic version fits within a set of constraints
-* Optionally work with a `v` prefix
-
-[![Stability:
-Active](https://masterminds.github.io/stability/active.svg)](https://masterminds.github.io/stability/active.html)
-[![](https://github.com/Masterminds/semver/workflows/Tests/badge.svg)](https://github.com/Masterminds/semver/actions)
-[![GoDoc](https://img.shields.io/static/v1?label=godoc&message=reference&color=blue)](https://pkg.go.dev/github.com/Masterminds/semver/v3)
-[![Go Report Card](https://goreportcard.com/badge/github.com/Masterminds/semver)](https://goreportcard.com/report/github.com/Masterminds/semver)
-
-If you are looking for a command line tool for version comparisons please see
-[vert](https://github.com/Masterminds/vert) which uses this library.
-
-## Package Versions
-
-There are three major versions fo the `semver` package.
-
-* 3.x.x is the new stable and active version. This version is focused on constraint
-  compatibility for range handling in other tools from other languages. It has
-  a similar API to the v1 releases. The development of this version is on the master
-  branch. The documentation for this version is below.
-* 2.x was developed primarily for [dep](https://github.com/golang/dep). There are
-  no tagged releases and the development was performed by [@sdboyer](https://github.com/sdboyer).
-  There are API breaking changes from v1. This version lives on the [2.x branch](https://github.com/Masterminds/semver/tree/2.x).
-* 1.x.x is the most widely used version with numerous tagged releases. This is the
-  previous stable and is still maintained for bug fixes. The development, to fix
-  bugs, occurs on the release-1 branch. You can read the documentation [here](https://github.com/Masterminds/semver/blob/release-1/README.md).
-
-## Parsing Semantic Versions
-
-There are two functions that can parse semantic versions. The `StrictNewVersion`
-function only parses valid version 2 semantic versions as outlined in the
-specification. The `NewVersion` function attempts to coerce a version into a
-semantic version and parse it. For example, if there is a leading v or a version
-listed without all 3 parts (e.g. `v1.2`) it will attempt to coerce it into a valid
-semantic version (e.g., 1.2.0). In both cases a `Version` object is returned
-that can be sorted, compared, and used in constraints.
-
-When parsing a version an error is returned if there is an issue parsing the
-version. For example,
-
-    v, err := semver.NewVersion("1.2.3-beta.1+build345")
-
-The version object has methods to get the parts of the version, compare it to
-other versions, convert the version back into a string, and get the original
-string. Getting the original string is useful if the semantic version was coerced
-into a valid form.
-
-## Sorting Semantic Versions
-
-A set of versions can be sorted using the `sort` package from the standard library.
-For example,
-
-```go
-raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",}
-vs := make([]*semver.Version, len(raw))
-for i, r := range raw {
-    v, err := semver.NewVersion(r)
-    if err != nil {
-        t.Errorf("Error parsing version: %s", err)
-    }
-
-    vs[i] = v
-}
-
-sort.Sort(semver.Collection(vs))
-```
-
-## Checking Version Constraints
-
-There are two methods for comparing versions. One uses comparison methods on
-`Version` instances and the other uses `Constraints`. There are some important
-differences to notes between these two methods of comparison.
-
-1. When two versions are compared using functions such as `Compare`, `LessThan`,
-   and others it will follow the specification and always include prereleases
-   within the comparison. It will provide an answer that is valid with the
-   comparison section of the spec at https://semver.org/#spec-item-11
-2. When constraint checking is used for checks or validation it will follow a
-   different set of rules that are common for ranges with tools like npm/js
-   and Rust/Cargo. This includes considering prereleases to be invalid if the
-   ranges does not include one. If you want to have it include pre-releases a
-   simple solution is to include `-0` in your range.
-3. Constraint ranges can have some complex rules including the shorthand use of
-   ~ and ^. For more details on those see the options below.
-
-There are differences between the two methods or checking versions because the
-comparison methods on `Version` follow the specification while comparison ranges
-are not part of the specification. Different packages and tools have taken it
-upon themselves to come up with range rules. This has resulted in differences.
-For example, npm/js and Cargo/Rust follow similar patterns while PHP has a
-different pattern for ^. The comparison features in this package follow the
-npm/js and Cargo/Rust lead because applications using it have followed similar
-patters with their versions.
-
-Checking a version against version constraints is one of the most featureful
-parts of the package.
-
-```go
-c, err := semver.NewConstraint(">= 1.2.3")
-if err != nil {
-    // Handle constraint not being parsable.
-}
-
-v, err := semver.NewVersion("1.3")
-if err != nil {
-    // Handle version not being parsable.
-}
-// Check if the version meets the constraints. The a variable will be true.
-a := c.Check(v)
-```
-
-### Basic Comparisons
-
-There are two elements to the comparisons. First, a comparison string is a list
-of space or comma separated AND comparisons. These are then separated by || (OR)
-comparisons. For example, `">= 1.2 < 3.0.0 || >= 4.2.3"` is looking for a
-comparison that's greater than or equal to 1.2 and less than 3.0.0 or is
-greater than or equal to 4.2.3.
-
-The basic comparisons are:
-
-* `=`: equal (aliased to no operator)
-* `!=`: not equal
-* `>`: greater than
-* `<`: less than
-* `>=`: greater than or equal to
-* `<=`: less than or equal to
-
-### Working With Prerelease Versions
-
-Pre-releases, for those not familiar with them, are used for software releases
-prior to stable or generally available releases. Examples of prereleases include
-development, alpha, beta, and release candidate releases. A prerelease may be
-a version such as `1.2.3-beta.1` while the stable release would be `1.2.3`. In the
-order of precedence, prereleases come before their associated releases. In this
-example `1.2.3-beta.1 < 1.2.3`.
-
-According to the Semantic Version specification prereleases may not be
-API compliant with their release counterpart. It says,
-
-> A pre-release version indicates that the version is unstable and might not satisfy the intended compatibility requirements as denoted by its associated normal version.
-
-SemVer comparisons using constraints without a prerelease comparator will skip
-prerelease versions. For example, `>=1.2.3` will skip prereleases when looking
-at a list of releases while `>=1.2.3-0` will evaluate and find prereleases.
-
-The reason for the `0` as a pre-release version in the example comparison is
-because pre-releases can only contain ASCII alphanumerics and hyphens (along with
-`.` separators), per the spec. Sorting happens in ASCII sort order, again per the
-spec. The lowest character is a `0` in ASCII sort order
-(see an [ASCII Table](http://www.asciitable.com/))
-
-Understanding ASCII sort ordering is important because A-Z comes before a-z. That
-means `>=1.2.3-BETA` will return `1.2.3-alpha`. What you might expect from case
-sensitivity doesn't apply here. This is due to ASCII sort ordering which is what
-the spec specifies.
-
-### Hyphen Range Comparisons
-
-There are multiple methods to handle ranges and the first is hyphens ranges.
-These look like:
-
-* `1.2 - 1.4.5` which is equivalent to `>= 1.2 <= 1.4.5`
-* `2.3.4 - 4.5` which is equivalent to `>= 2.3.4 <= 4.5`
-
-### Wildcards In Comparisons
-
-The `x`, `X`, and `*` characters can be used as a wildcard character. This works
-for all comparison operators. When used on the `=` operator it falls
-back to the patch level comparison (see tilde below). For example,
-
-* `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
-* `>= 1.2.x` is equivalent to `>= 1.2.0`
-* `<= 2.x` is equivalent to `< 3`
-* `*` is equivalent to `>= 0.0.0`
-
-### Tilde Range Comparisons (Patch)
-
-The tilde (`~`) comparison operator is for patch level ranges when a minor
-version is specified and major level changes when the minor number is missing.
-For example,
-
-* `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0`
-* `~1` is equivalent to `>= 1, < 2`
-* `~2.3` is equivalent to `>= 2.3, < 2.4`
-* `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
-* `~1.x` is equivalent to `>= 1, < 2`
-
-### Caret Range Comparisons (Major)
-
-The caret (`^`) comparison operator is for major level changes once a stable
-(1.0.0) release has occurred. Prior to a 1.0.0 release the minor versions acts
-as the API stability level. This is useful when comparisons of API versions as a
-major change is API breaking. For example,
-
-* `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0`
-* `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0`
-* `^2.3` is equivalent to `>= 2.3, < 3`
-* `^2.x` is equivalent to `>= 2.0.0, < 3`
-* `^0.2.3` is equivalent to `>=0.2.3 <0.3.0`
-* `^0.2` is equivalent to `>=0.2.0 <0.3.0`
-* `^0.0.3` is equivalent to `>=0.0.3 <0.0.4`
-* `^0.0` is equivalent to `>=0.0.0 <0.1.0`
-* `^0` is equivalent to `>=0.0.0 <1.0.0`
-
-## Validation
-
-In addition to testing a version against a constraint, a version can be validated
-against a constraint. When validation fails a slice of errors containing why a
-version didn't meet the constraint is returned. For example,
-
-```go
-c, err := semver.NewConstraint("<= 1.2.3, >= 1.4")
-if err != nil {
-    // Handle constraint not being parseable.
-}
-
-v, err := semver.NewVersion("1.3")
-if err != nil {
-    // Handle version not being parseable.
-}
-
-// Validate a version against a constraint.
-a, msgs := c.Validate(v)
-// a is false
-for _, m := range msgs {
-    fmt.Println(m)
-
-    // Loops over the errors which would read
-    // "1.3 is greater than 1.2.3"
-    // "1.3 is less than 1.4"
-}
-```

-Package semver provides the ability to work with Semantic Versions (http://semver.org) in Go.
-
-Specifically it provides the ability to:
-
-    * Parse semantic versions
-    * Sort semantic versions
-    * Check if a semantic version fits within a set of constraints
-    * Optionally work with a `v` prefix
-
-Parsing Semantic Versions
-
-There are two functions that can parse semantic versions. The `StrictNewVersion`
-function only parses valid version 2 semantic versions as outlined in the
-specification. The `NewVersion` function attempts to coerce a version into a
-semantic version and parse it. For example, if there is a leading v or a version
-listed without all 3 parts (e.g. 1.2) it will attempt to coerce it into a valid
-semantic version (e.g., 1.2.0). In both cases a `Version` object is returned
-that can be sorted, compared, and used in constraints.
-
-When parsing a version an optional error can be returned if there is an issue
-parsing the version. For example,
-
-    v, err := semver.NewVersion("1.2.3-beta.1+b345")
-
-The version object has methods to get the parts of the version, compare it to
-other versions, convert the version back into a string, and get the original
-string. For more details please see the documentation
-at https://godoc.org/github.com/Masterminds/semver.
-
-Sorting Semantic Versions
-
-A set of versions can be sorted using the `sort` package from the standard library.
-For example,
-
-    raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",}
-    vs := make([]*semver.Version, len(raw))
-	for i, r := range raw {
-		v, err := semver.NewVersion(r)
-		if err != nil {
-			t.Errorf("Error parsing version: %s", err)
-		}
-
-		vs[i] = v
-	}
-
-	sort.Sort(semver.Collection(vs))
-
-Checking Version Constraints and Comparing Versions
-
-There are two methods for comparing versions. One uses comparison methods on
-`Version` instances and the other is using Constraints. There are some important
-differences to notes between these two methods of comparison.
-
-1. When two versions are compared using functions such as `Compare`, `LessThan`,
-   and others it will follow the specification and always include prereleases
-   within the comparison. It will provide an answer valid with the comparison
-   spec section at https://semver.org/#spec-item-11
-2. When constraint checking is used for checks or validation it will follow a
-   different set of rules that are common for ranges with tools like npm/js
-   and Rust/Cargo. This includes considering prereleases to be invalid if the
-   ranges does not include on. If you want to have it include pre-releases a
-   simple solution is to include `-0` in your range.
-3. Constraint ranges can have some complex rules including the shorthard use of
-   ~ and ^. For more details on those see the options below.
-
-There are differences between the two methods or checking versions because the
-comparison methods on `Version` follow the specification while comparison ranges
-are not part of the specification. Different packages and tools have taken it
-upon themselves to come up with range rules. This has resulted in differences.
-For example, npm/js and Cargo/Rust follow similar patterns which PHP has a
-different pattern for ^. The comparison features in this package follow the
-npm/js and Cargo/Rust lead because applications using it have followed similar
-patters with their versions.
-
-Checking a version against version constraints is one of the most featureful
-parts of the package.
-
-    c, err := semver.NewConstraint(">= 1.2.3")
-    if err != nil {
-        // Handle constraint not being parsable.
-    }
-
-    v, err := semver.NewVersion("1.3")
-    if err != nil {
-        // Handle version not being parsable.
-    }
-    // Check if the version meets the constraints. The a variable will be true.
-    a := c.Check(v)
-
-Basic Comparisons
-
-There are two elements to the comparisons. First, a comparison string is a list
-of comma or space separated AND comparisons. These are then separated by || (OR)
-comparisons. For example, `">= 1.2 < 3.0.0 || >= 4.2.3"` is looking for a
-comparison that's greater than or equal to 1.2 and less than 3.0.0 or is
-greater than or equal to 4.2.3. This can also be written as
-`">= 1.2, < 3.0.0 || >= 4.2.3"`
-
-The basic comparisons are:
-
-    * `=`: equal (aliased to no operator)
-    * `!=`: not equal
-    * `>`: greater than
-    * `<`: less than
-    * `>=`: greater than or equal to
-    * `<=`: less than or equal to
-
-Hyphen Range Comparisons
-
-There are multiple methods to handle ranges and the first is hyphens ranges.
-These look like:
-
-    * `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5`
-    * `2.3.4 - 4.5` which is equivalent to `>= 2.3.4 <= 4.5`
-
-Wildcards In Comparisons
-
-The `x`, `X`, and `*` characters can be used as a wildcard character. This works
-for all comparison operators. When used on the `=` operator it falls
-back to the tilde operation. For example,
-
-    * `1.2.x` is equivalent to `>= 1.2.0 < 1.3.0`
-    * `>= 1.2.x` is equivalent to `>= 1.2.0`
-    * `<= 2.x` is equivalent to `<= 3`
-    * `*` is equivalent to `>= 0.0.0`
-
-Tilde Range Comparisons (Patch)
-
-The tilde (`~`) comparison operator is for patch level ranges when a minor
-version is specified and major level changes when the minor number is missing.
-For example,
-
-    * `~1.2.3` is equivalent to `>= 1.2.3 < 1.3.0`
-    * `~1` is equivalent to `>= 1, < 2`
-    * `~2.3` is equivalent to `>= 2.3 < 2.4`
-    * `~1.2.x` is equivalent to `>= 1.2.0 < 1.3.0`
-    * `~1.x` is equivalent to `>= 1 < 2`
-
-Caret Range Comparisons (Major)
-
-The caret (`^`) comparison operator is for major level changes once a stable
-(1.0.0) release has occurred. Prior to a 1.0.0 release the minor versions acts
-as the API stability level. This is useful when comparisons of API versions as a
-major change is API breaking. For example,
-
-    * `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0`
-    * `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0`
-    * `^2.3` is equivalent to `>= 2.3, < 3`
-    * `^2.x` is equivalent to `>= 2.0.0, < 3`
-    * `^0.2.3` is equivalent to `>=0.2.3 <0.3.0`
-    * `^0.2` is equivalent to `>=0.2.0 <0.3.0`
-    * `^0.0.3` is equivalent to `>=0.0.3 <0.0.4`
-    * `^0.0` is equivalent to `>=0.0.0 <0.1.0`
-    * `^0` is equivalent to `>=0.0.0 <1.0.0`
-
-Validation
-
-In addition to testing a version against a constraint, a version can be validated
-against a constraint. When validation fails a slice of errors containing why a
-version didn't meet the constraint is returned. For example,
-
-    c, err := semver.NewConstraint("<= 1.2.3, >= 1.4")
-    if err != nil {
-        // Handle constraint not being parseable.
-    }
-
-    v, _ := semver.NewVersion("1.3")
-    if err != nil {
-        // Handle version not being parseable.
-    }
-
-    // Validate a version against a constraint.
-    a, msgs := c.Validate(v)
-    // a is false
-    for _, m := range msgs {
-        fmt.Println(m)
-
-        // Loops over the errors which would read
-        // "1.3 is greater than 1.2.3"
-        // "1.3 is less than 1.4"
-    }
