-# Contributions
+##### Using `configuration-path` input together with the `@actions/checkout` action
+You might want to use action called [@actions/checkout](https://github.com/actions/checkout) to upload label configuration file onto the runner from the current or any other repositories. See usage example below:
+
+```yml
+    steps:
+    - uses: actions/checkout@v3 # Uploads repository content to the runner
+      with:
+        repository: "owner/repositoryName" # The one of the available inputs, visit https://github.com/actions/checkout#readme to find more
+    - uses: actions/labeler@v4
+```
+
+##### Peculiarities of using the `dot` input
+
+When `dot` is disabled, and you want to include _all_ files in a folder:
+
+```yml
+label1:
+- path/to/folder/**/*
+- path/to/folder/**/.*
+```
+
+If `dot` is enabled:
+
+```yml
+label1:
+- path/to/folder/**
+```
+
+##### Example workflow specifying Pull request numbers
+
+```yml
+name: "Label Previous Pull Requests"
+on:
+  schedule:
+    - cron: "0 1 * * 1"
+
+jobs:
+  triage:
+    permissions:
+      contents: read
+      pull-requests: write
+    runs-on: ubuntu-latest
+    steps:
+    
+    # Label PRs 1, 2, and 3
+    - uses: actions/labeler@v4
+      with:        
+        pr-number: |
+          1
+          2
+          3
+```
+
+**Note:** in normal usage the `pr-number` input is not required as the action will detect the PR number from the workflow context.
+
+#### Outputs 
+
+Labeler provides the following outputs:  
+
+| Name         | Description                                               |
+|--------------|-----------------------------------------------------------|
+| `new-labels` | A comma-separated list of all new labels                  |
+| `all-labels` | A comma-separated list of all labels that the PR contains |
+
+The following example performs steps based on the output of labeler:
+```yml
+name: "My workflow"
+on:
+- pull_request_target
+
+jobs:
+  triage:
+    permissions:
+      contents: read
+      pull-requests: write
+    runs-on: ubuntu-latest
+    steps:
+    - id: label-the-PR
+      uses: actions/labeler@v4
+      
+    - id: run-frontend-tests
+      if: contains(steps.label-the-PR.outputs.all-labels, 'frontend')
+      run: |
+        echo "Running frontend tests..."
+        # Put your commands for running frontend tests here
+  
+    - id: run-backend-tests
+      if: contains(steps.label-the-PR.outputs.all-labels, 'backend')
+      run: |
+        echo "Running backend tests..."
+        # Put your commands for running backend tests here
+```
+
+## Permissions
+
+In order to add labels to pull requests, the GitHub labeler action requires write permissions on the pull-request. However, when the action runs on a pull request from a forked repository, GitHub only grants read access tokens for `pull_request` events, at most. If you encounter an `Error: HttpError: Resource not accessible by integration`, it's likely due to these permission constraints. To resolve this issue, you can modify the `on:` section of your workflow to use
+[`pull_request_target`](https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#pull_request_target) instead of `pull_request` (see example [above](#create-workflow)). This change allows the action to have write access, because `pull_request_target` alters the [context of the action](https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#pull_request_target) and safely grants additional permissions. Refer to the [GitHub token permissions documentation](https://docs.github.com/en/actions/security-guides/automatic-token-authentication#permissions-for-the-github_token) for more details about access levels and event contexts.
