 ### 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.
+[**Note**][naming-conventions]: When you set a custom environment variable, you cannot use any of the default environment variable names. For a complete list of these, see [Default environment variables][default-environment-variables]. **If you attempt to override the value of one of these default environment variables, the assignment is ignored.**
 
-Currently, a GitHub workflow setting a `GITHUB_` variable will not cause an error, it will just fail silently.
+If a variable start to be used as default environment variable, the environment variable may have a different behavior than the expected one.
-And if a custom `GITHUB_` variable is in conflict with an official `GITHUB_` variable, the offical `GITHUB_` variable will override custom one.
 
-<details>
+If this append, the `${{ env.GITHUB_AWESOME_VARIABLE }}` and `$GITHUB_AWESOME_VARIABLE` expression will not works in the same way.
-  <summary>Test workflow</summary>
+
-  <p>
+- `${{ env.GITHUB_AWESOME_VARIABLE }}` will serve the behavior of this action,
+- `$GITHUB_AWESOME_VARIABLE` will serve the behavior of GitHub Action.
+
+Otherwise the two expression will serve the behavior of this action.
+This will not occurs if you use the `prefix` input to avoid the issue.
+
+**NOTE:** If detected, the maintainers of this action will choose the best course of action depending of the impact.
+
+#### Known environment variable conflicts
+
+##### GITHUB_REF_NAME
+
+The behavior is the same as the GitHub one except on `pull_request*` workflows ([Ready the full story][issue-104]).
+
+- `${{ env.GITHUB_REF_NAME }}` will serve the behavior of this action,
+- `$GITHUB_REF_NAME` will serve the behavior of GitHub Action.
+
+On `pull_request*` workflows, the content will be `<PR-number>/merge` instead of the branch name.
+
+A possible workaround is to use `prefix` input available in `v4` version
 
 ```yaml
-name: Test
+- name: Inject slug/short variables
-on: push
+  uses: rlespinasse/github-slug-action@v4
-jobs:
+  with:
-  build:
+    prefix: CI_

-    steps:
-      - run: echo ${GITHUB_REF}
-      # print "refs/heads/v3.x"
-      - run: echo "GITHUB_REF=one_value" >> "$GITHUB_ENV"
-      - run: echo ${GITHUB_REF}

-      # print "another_value"

+Then `${{ env.CI_GITHUB_REF_NAME }}`, and `$CI_GITHUB_REF_NAME` will serve the behavior of this action.
