 ### 1. Create a GitHub Personal Access Token
 
-1. Go to [GitHub Settings > Developer settings > Personal access tokens](https://github.com/settings/tokens)
-2. Click "Generate new token (classic)"
-3. Select these scopes:
-   - `repo` (Full control of private repositories)
-   - `read:user` (Read access to user profile data)
-   - `actions:read` (Read access to actions and workflows)
+1. Classic Personal Access Token (legacy)
+   1. Go to `GitHub Settings > Developer settings > Personal access tokens`
+   2. Click `Generate new token (classic)`
+   3. Select these scopes:
+      - `repo` (Full control of private repositories)
+      - `read:user` (Read access to user profile data)
+      - `actions:read` (Read access to actions and workflows)
+   4. Notes: Classic tokens are broad — choose a short expiration and store the token securely.
+
+2. Recommended: Fine‑Grained Personal Access Token (FGA)
+   1. Go to `GitHub Settings > Developer settings > Personal access tokens > Fine‑grained tokens`
+   2. Click `Generate new token`
+   3. Under **Repository access** choose `Selected repositories` (preferred) or `All repositories` only if necessary
+   4. Under **Repository permissions** set:
+      - `Actions` = `Read` (analysis only). If you plan to run `--cleanup` to delete artifacts, set `Actions` = `Read & write` for the repositories you will modify
+      - `Contents` = `Read`
+      - `Users` = `Read` (only if the tool queries the authenticated user's profile)
+   5. Set a reasonable expiration and create the token
+   6. Save the token securely and export it as an environment variable (PowerShell examples below)

-### Common Issues
-
-**"API rate limit exceeded"**
-- The tool includes built-in rate limiting, but with many repositories, you might hit limits
-- Wait and try again, or run the analysis in smaller batches
-
-**"Repository not found or no access"**
-- Ensure your token has the correct permissions
-- Check that the repository exists and you have access
-
-**"Access forbidden - check token permissions"**
-- Verify your token has `repo`, `read:user`, and `actions:read` scopes
-- For organization repositories, you might need additional permissions
-
-**"No artifacts found"**
-- Repository might not have any GitHub Actions workflows
-- Workflows might not generate artifacts
-- Artifacts might have all expired
-
-### Getting Help
-
-1. Check the GitHub API status: https://www.githubstatus.com/
-2. Verify your token permissions
-3. Try analyzing a single repository first
-4. Open an issue with detailed error messages
