+# Git: git-auth-global
+
+## Behavior
+
+Modify git global config:
+  - authenticate requests to github.com with Github token
+
+Global config is cleared in post run
+
+_useful to use private pre-commit sources in CI_
+
+## Usage
+
+```yaml
+jobs:
+  advanceTag:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: "actions/checkout@v3"
+
+      - name: "Git Auth Global"
+        uses: "meero-com/github-actions-shared-workflows/actions/git/git-auth-global@main"
+        with:
+          github-token: ${{ secrets.API_TOKEN_GITHUB }}
+```
+
+Beware of using a `@ref` (`@main` in the example above) which suits your stability requirements in your workflow:
+
+* Use `@main` if you always want to use the latest version of the workflow.
+* Use `@<tag>` if you wan to use a specific frozen version of the workflow.
