 # agentics-template
 A template to get started with GitHub Agentic Workflows
+
+## Getting Started
+
+This repository is a template for creating GitHub Agentic Workflows. Agentic workflows allow you to use AI agents (like GitHub Copilot) to automate tasks in your repository.
+
+## Configuring Tokens for Agentic Workflows
+
+GitHub Agentic Workflows require specific tokens to authenticate with various services. GitHub Actions always provides `GITHUB_TOKEN` automatically, but for advanced features like Copilot workflows, you'll need to configure additional tokens.
+
+### Quick Start: Tokens You Need to Configure
+
+Create these repository secrets based on what features you need:
+
+| When you need this... | Secret to create | Notes |
+|----------------------|------------------|-------|
+| Cross-repo operations / remote GitHub tools | `GH_AW_GITHUB_TOKEN` | PAT or app token with cross-repo access |
+| Copilot workflows (CLI, engine, agent tasks, etc.) | `COPILOT_GITHUB_TOKEN` | Needs Copilot Requests permission and repo access |
+| Assigning agents/bots to issues or pull requests | `GH_AW_AGENT_TOKEN` | Used by `assign-to-agent` and Copilot assignee/reviewer flows |
+| Any GitHub Projects v2 operations | `GH_AW_PROJECT_GITHUB_TOKEN` | **Required** for `update-project`. Default `GITHUB_TOKEN` cannot access Projects v2 API |
+| Isolating MCP server permissions (advanced optional) | `GH_AW_GITHUB_MCP_SERVER_TOKEN` | Only if you want MCP to use a different token than other jobs |
+
+### Step-by-Step: Configuring Tokens for Copilot
+
+Follow these steps to set up GitHub Copilot in your agentic workflows:
+
+#### 1. Create a Personal Access Token for Copilot
+
+1. Go to [GitHub Personal Access Tokens settings](https://github.com/settings/personal-access-tokens/new)
+2. Configure the token:
+   - **Resource owner**: Your user account (not organization)
+   - **Repository access**: "Public repositories" or select specific repos
+   - **Permissions**: Select "Copilot Requests" (required)
+3. Generate the token and copy it
+
+#### 2. Set the Copilot Token as a Repository Secret
+
+Add the token as a repository secret using the GitHub website:
+
+1. Go to your repository on GitHub
+2. Click **Settings** > **Secrets and variables** > **Actions**
+3. Click **New repository secret**
+4. Set the name to `COPILOT_GITHUB_TOKEN`
+5. Paste your Personal Access Token in the **Secret** field
+6. Click **Add secret**
+
+#### 3. (Optional) Configure Additional Tokens
+
+If you need additional capabilities, add these tokens as repository secrets following the same steps above:
+
+- **For cross-repository operations**: Create a secret named `GH_AW_GITHUB_TOKEN`
+- **For agent assignment operations**: Create a secret named `GH_AW_AGENT_TOKEN`
+- **For GitHub Projects v2 operations**: Create a secret named `GH_AW_PROJECT_GITHUB_TOKEN`
+
+## Creating Workflows
+
+### Using the Create Agentic Workflow Agent
+
+The easiest way to create a new agentic workflow is to use the built-in custom agent:
+
+1. Go to your repository on GitHub
+2. Click on the **Actions** tab
+3. Click **Create new agentic task**
+4. In the agent selection, choose **create-agentic-workflow**
+5. Describe what you want your workflow to do (e.g., "Create a workflow that triages new issues and adds labels")
+6. The agent will generate the workflow file for you
+
+### Debugging and Improving Workflows
+
+If you encounter issues with a workflow or want to improve it:
+
+1. Go to your repository on GitHub
+2. Click on the **Actions** tab
+3. Click **Create new agentic task**
+4. In the agent selection, choose **debug-agentic-workflow**
+5. Provide the GitHub URL to your failed workflow run (e.g., `https://github.com/owner/repo/actions/runs/12345`)
+6. The agent will analyze the logs and suggest fixes or improvements
