 Does your workflow change a file, but "git-auto-commit" does not detect the change? Check the `.gitignore` that applies to the respective file. You might have accidentally marked the file to be ignored by git.
 
-## Hooks
-
-The action supports custom bash scripts that can be executed at various points during the git workflow. This allows for custom preparation, validation, or post-processing steps.
-
-### Available Hooks
-
-- **`pre_status_hook`** - Executed before checking git status. Useful for repository preparation like `git fetch --unshallow`.
-- **`pre_commit_hook`** - Executed after detecting changes but before adding files. Allows modification of files that will be included in the commit.
-- **`pre_push_hook`** - Executed after committing but before pushing to remote. Useful for final validation.
-- **`post_push_hook`** - Executed after successfully pushing changes. Useful for notifications or cleanup.
-
-### Hook Examples
-
-#### Unshallow Repository Before Checking Status
-
-This example addresses the common issue where workflows use shallow checkouts (`fetch-depth: 1`) for performance, but need to unshallow before merging or when full history is required for certain operations.
-
-```yaml
-name: Update Submodules
-on: [push]
-
-jobs:
-  update-submodules:
-    runs-on: ubuntu-latest
-    steps:
-    - uses: actions/checkout@v4
-      with:
-        fetch-depth: 1  # Shallow checkout for performance
-        submodules: recursive
-
-    - name: Update submodule to latest
-      run: |
-        git submodule update --remote
-        
-    - name: Commit submodule updates
-      uses: stefanzweifel/git-auto-commit-action@v6
-      with:
-        file_pattern: .gitmodules *
-        commit_message: "Update submodules to latest versions"
-        pre_status_hook: |
-          # Only unshallow if we have changes and need to merge
-          if git status --porcelain | grep -q .; then
-            echo "Changes detected, checking if repository is shallow..."
-            if git rev-parse --is-shallow-repository 2>/dev/null | grep -q true; then
-              echo "Repository is shallow, running git fetch --unshallow"
-              git fetch --unshallow
-            fi
-          fi
-```
-
-#### Addressing "refusing to merge unrelated histories" Error
-
-This specific example addresses the use case discussed in [GitHub Issue #365](https://github.com/stefanzweifel/git-auto-commit-action/discussions/365), where shallow repositories can cause merge conflicts:
-
-```yaml
-name: Update Dependencies with Unshallow

-
-#### Validate Files Before Committing
-
-```yaml
-- name: Commit with validation
-  uses: stefanzweifel/git-auto-commit-action@v6
-  with:
-    commit_message: Apply automatic changes
-    pre_commit_hook: |
-      echo "Running validation..."
-      npm run lint
-      npm run test
-```
-
-#### Generate Additional Files in Pre-Commit Hook
-
-```yaml
-- name: Commit with file generation
-  uses: stefanzweifel/git-auto-commit-action@v6
-  with:
-    commit_message: Update files and manifest
-    pre_commit_hook: |
-      echo "Generating manifest..."
-      echo "Build timestamp: $(date)" > build-info.txt
-      echo "Commit: $GITHUB_SHA" >> build-info.txt
-```
-
-#### Notify After Successful Push
-
-```yaml
-- name: Commit and notify
-  uses: stefanzweifel/git-auto-commit-action@v6
-  with:
-    commit_message: Apply automatic changes
-    post_push_hook: |
-      echo "Changes successfully pushed!"
-      curl -X POST -H 'Content-type: application/json' \
-        --data '{"text":"Code changes have been committed and pushed"}' \
-        "$SLACK_WEBHOOK_URL"
-```
-
-### Hook Error Handling
-
-If any hook fails (exits with non-zero status), the entire action will fail and stop execution. This ensures that validation hooks can prevent commits/pushes when issues are detected.
-
-```yaml
-- name: Commit with strict validation
-  uses: stefanzweifel/git-auto-commit-action@v6
-  with:
-    commit_message: Apply automatic changes
-    pre_commit_hook: |
-      # This will fail the action if any .js files have syntax errors
-      find . -name "*.js" -exec node -c {} \;
-```
-
-### Hook Execution Context
-
-- Hooks are executed in the repository directory
-- Hooks have access to all git commands and repository state
-- Hooks can access GitHub Actions environment variables
-- Files created/modified by `pre_commit_hook` will be included in the commit
-- Hooks run in bash and support multi-line scripts
