+Git Velocity requires specific GitHub API permissions to fetch repository data. Below are the required permissions for each authentication method.
+
+### Personal Access Token (Classic)
+
+When creating a classic Personal Access Token, select the following scopes:
+
+| Scope | Required | Description |
+|-------|----------|-------------|
+| `repo` | ✅ Yes | Full access to private repositories (includes commits, PRs, issues) |
+| `read:org` | ⚠️ If using org patterns | Required when using `pattern: "*"` to list organization repositories |
+
+> **Note**: For public repositories only, the `public_repo` scope is sufficient instead of full `repo` access.
+
+### Fine-Grained Personal Access Token (Recommended)
+
+Fine-grained tokens provide more granular control. Configure the following permissions:
+
+**Repository Permissions:**
+| Permission | Access Level | Description |
+|------------|--------------|-------------|
+| Contents | Read | Access commit data and file contents |
+| Pull requests | Read | Access PR data, reviews, and comments |
+| Issues | Read | Access issue data and comments |
+| Metadata | Read | Basic repository information (automatically included) |
+
+**Account Permissions:**
+| Permission | Access Level | Description |
+|------------|--------------|-------------|
+| Email addresses | Read | Access public email for user deduplication |
+
+### GitHub App Authentication
+
+When using GitHub App authentication, configure the following permissions:
+
+**Repository Permissions:**
+| Permission | Access Level | Description |
+|------------|--------------|-------------|
+| Contents | Read | Fetch commits and diffs |
+| Pull requests | Read | Fetch PRs, reviews, and review comments |
+| Issues | Read | Fetch issues and issue comments |
+| Metadata | Read | Repository metadata (required) |
+
+**Organization Permissions (if using org patterns):**
+| Permission | Access Level | Description |
+|------------|--------------|-------------|
+| Members | Read | List organization repositories |
+
+**Account Permissions:**
+| Permission | Access Level | Description |
+|------------|--------------|-------------|
+| Email addresses | Read | User profile deduplication |
+
+### GitHub Actions (GITHUB_TOKEN)
+
+When running in GitHub Actions, the default `GITHUB_TOKEN` has sufficient permissions for repositories in the same organization/account. For cross-organization access, use a PAT or GitHub App.
+
+### API Endpoints Used
+
+Git Velocity uses the following GitHub REST API endpoints:
+
+| Endpoint | Purpose |
+|----------|---------|
+| `GET /orgs/{org}/repos` | List repositories by organization |
+| `GET /repos/{owner}/{repo}/commits` | Fetch commit history |
+| `GET /repos/{owner}/{repo}/commits/{sha}` | Fetch commit details with diff |
+| `GET /repos/{owner}/{repo}/pulls` | List pull requests |
+| `GET /repos/{owner}/{repo}/pulls/{number}/reviews` | Fetch PR reviews |
+| `GET /repos/{owner}/{repo}/issues` | List issues |
+| `GET /users/{username}` | Fetch user profile information |

+### Bot Filtering
+
+Bot filtering uses **hardcoded default patterns** that always apply when `include_bots: false`. These cannot be disabled to ensure consistent filtering:
+
+**Default Bot Patterns (always applied):**
+- `*[bot]` - GitHub App bots (dependabot[bot], renovate[bot], etc.)
+- `dependabot*` - Dependabot variants
+- `renovate*` - Renovate bot variants
+- `github-actions*` - GitHub Actions
+- `codecov*` - Codecov bot
+- `snyk*` - Snyk security bot
+- `greenkeeper*` - Greenkeeper (legacy)
+- `imgbot*` - Image optimization bot
+- `allcontributors*` - All Contributors bot
+- `semantic-release*` - Semantic release bot
+
+**Add custom patterns** for your organization's bots:
+
+```yaml
+options:
+  include_bots: false  # When false, hardcoded + additional patterns apply
+  additional_bot_patterns:
+    - "my-org-bot"     # Exact match
+    - "jenkins*"       # Prefix match
+    - "*-ci"           # Suffix match
+```
+
+### Meaningful Lines Filtering
+
+Git Velocity always filters out non-meaningful code changes when scoring line additions and deletions. This provides an accurate measure of actual code contributions.
+
+**What's filtered out:**
+- **Comments**: Single-line (`//`, `#`, `--`), block (`/* */`, `<!-- -->`), docstrings (`"""`, `'''`)
+- **Whitespace**: Empty lines, whitespace-only lines
+- **Documentation files**: `.md`, `.rst`, `.txt`, `README`, `CHANGELOG`, `LICENSE`, files in `docs/` directories
+
+**Supported comment styles:**
+- C-style: `//`, `/* */`, `*` (block continuation)
+- Python/Shell: `#`, `"""`, `'''`
+- SQL/Lua/Haskell: `--`
+- Assembly/Lisp/INI: `;`
+- VB: `'`
+- HTML/XML: `<!-- -->`
