+- remove leading and trailing `-` character
+- limit the string size to 63 characters
+
+<details>
+  <summary>Others <b>Slug-ish</b> commands are available</summary>
+  <p>
+
+- `SLUG_URL` on a variable to have a `slug` variable compliant to be used in an URL
+  - Like `SLUG` but `.` is also replaced by `-`
+- `SHORT` on a variable will limit the string size to ~8 characters
+  - Useful for _sha_ value
+- `<KEY>_PART` on a variable will give a part of a variable defined by a key
+  - Like `GITHUB_REPOSITORY_OWNER_PART` for the owner part of `GITHUB_REPOSITORY`
+- `<VAR>_CS` on others variables to keep the value case-sensitive
+  - Like `GITHUB_REF_SLUG_CS`

+Additional enhanced environment variables can be compute to help you around GitHub environment variables.

+Others configurations
 
-### GITHUB_REF_SLUG
+- With a prefix
 
-Slug the environment variable **GITHUB_REF**
+  ```yaml
+  - name: Inject slug/short variables
+    uses: rlespinasse/github-slug-action@v4
+    with:
+      prefix: CI_
+  ```
 
-The branch or tag ref that triggered the workflow.
-_If neither a branch or tag is available for the event type, the variable will not exist._
+- With another max length for slug values
 
-| Environment variable (GITHUB_REF) | Slug variable (GITHUB_REF_SLUG) |

-| refs/heads/New_Awesome_Product    | new-awesome-product             |
+  ```yaml
+  - name: Inject slug/short variables
+    uses: rlespinasse/github-slug-action@v4
+    with:
+      slug-maxlength: 80 # Use 'nolimit' to remove use of a max length (Default to 63)
+  ```
 
-_Additional variables (only set for forked repositories) :_
+- With another length for short values
 
-- `GITHUB_HEAD_REF_SLUG` : The branch of the head repository **GITHUB_HEAD_REF**,
-- `GITHUB_BASE_REF_SLUG` : The branch of the base repository **GITHUB_BASE_REF**.
+  ```yaml
+  - name: Inject slug/short variables
+    uses: rlespinasse/github-slug-action@v4
+    with:
+      short-length: 7 # By default it's up to git to decide, use 8 to have the v3.x behavior
+  ```
 
-### GITHUB_SHA_SHORT
+  **Warning**: If you leave it empty, you need to checkout the source first in order to let git decide the size by itself.
 
-Short the environment variable **GITHUB_SHA**
+Check for more [examples][examples] (OS usage, URL use, ...)
 
-The commit SHA that triggered the workflow
+**Tip:** Use [Dependabot][dependabot] to maintain your `github-slug-action` version updated in your GitHub workflows.
 
-| Environment variable (GITHUB_SHA)        | Short variable (GITHUB_SHA_SHORT) |

+### Migration from previous versions
+
+The short sha length is not the same as previous version.
+
+- `v4` let git configuration decide of it (but you can override it),
+- `v3` and before, it's always a length of 8 characters.
+
+So to reproduce previous behavior, use
+
+```yaml
+- name: Inject slug/short variables
+  uses: rlespinasse/github-slug-action@v4
+  with:
+    short-length: 8 # Same as v3 and before
+```
+
+## Available Environment variables
+
+**Note**: If you don't find what you search for, read more about [available `GitHub` variables](docs/github-variables.md), and propose a [new custom variable][custom-variable].
+
+### Enhanced variables
+
+- `GITHUB_REF_NAME` will contains the reference name (branch or tag)
+  - based on `GITHUB_HEAD_REF` in a [`pull-request*`][webhooks-and-events] event context,
+  - based on `GITHUB_REF` in others event context.
+
+**NOTE:** All enhanced variables are available in all **slug** formats.

+## Troubleshooting
+
+### The SHORT variables doesn't have the same lengths as before
+
+Since `v4`, it's git who manage the short variables by using [git rev-parse][git-revparse] behaviour.
+The length of a short sha depends of the size of our repository and can differ over time.
+
+To manage that moving length, you can use `short-length` input
+
+- set `7` to reproduce `small repository` behavior
+- set `8` to reproduce `v3` behavior
+
+**Warning**: The minimum length is 4, the default is the effective value of the [core.abbrev][git-core-abbrev] configuration variable.
+
+### One of the environment variables doesn't work as intended
+
+[**Note**][naming-conventions]: GitHub reserves the `GITHUB_` environment variable prefix for internal use by GitHub. Setting an environment variable or secret with the `GITHUB_` prefix will result in an error.
+
+Currently, a GitHub workflow setting a `GITHUB_` variable will not cause an error, it will just fail silently.
+And if a custom `GITHUB_` variable is in conflict with an official `GITHUB_` variable, the offical `GITHUB_` variable will override custom one.

+A GitHub repository can used one of the available branches as action inside its workflows.
+
+### End of Life of a branch
+
+When a branch is not supported anymore, the following process occurs
+
+- Since `v4.x` branch, the branch will be deleted 2 major versions after
+  - So `v4.x` branch will be deleted when `v7.x` branch will have its first release
+  - prefer the `v4` tag to `v4.x` branch as reference in our workflow, 
+- Before `v4.x` branch, the branch will be converted into a tag when the support is dropped
+  - So `v3.x` branch will be converted as tag when `v5.x` branch will have its first release
