+## [2.2.0] - 2025-12-21
+
+### 🚀 Private Config Repositories - Team Collaboration Unlocked
+
+This major release adds **git-based config sources**, enabling teams to fetch configs from private/team repositories in addition to the public API. This unlocks team collaboration, enterprise deployment, and custom config collections.
+
+### 🎯 Major Features
+
+#### Git-Based Config Sources (Issue [#211](https://github.com/yusufkaraaslan/Skill_Seekers/issues/211))
+- **Multi-source config management** - Fetch from API, git URL, or named sources
+- **Private repository support** - GitHub, GitLab, Bitbucket, Gitea, and custom git servers
+- **Team collaboration** - Share configs across 3-5 person teams with version control
+- **Enterprise scale** - Support 500+ developers with priority-based resolution
+- **Secure authentication** - Environment variable tokens only (GITHUB_TOKEN, GITLAB_TOKEN, etc.)
+- **Intelligent caching** - Shallow clone (10-50x faster), auto-pull updates
+- **Offline mode** - Works with cached repos when offline
+- **Backward compatible** - Existing API-based configs work unchanged
+
+#### New MCP Tools
+- **`add_config_source`** - Register git repositories as config sources
+  - Auto-detects source type (GitHub, GitLab, etc.)
+  - Auto-selects token environment variable
+  - Priority-based resolution for multiple sources
+  - SSH URL support (auto-converts to HTTPS + token)
+
+- **`list_config_sources`** - View all registered sources
+  - Shows git URL, branch, priority, token env
+  - Filter by enabled/disabled status
+  - Sorted by priority (lower = higher priority)
+
+- **`remove_config_source`** - Unregister sources
+  - Removes from registry (cache preserved for offline use)
+  - Helpful error messages with available sources
+
+- **Enhanced `fetch_config`** - Three modes
+  1. **Named source mode** - `fetch_config(source="team", config_name="react-custom")`
+  2. **Git URL mode** - `fetch_config(git_url="https://...", config_name="react-custom")`
+  3. **API mode** - `fetch_config(config_name="react")` (unchanged)
+
+### Added
+
+#### Core Infrastructure
+- **GitConfigRepo class** (`src/skill_seekers/mcp/git_repo.py`, 283 lines)
+  - `clone_or_pull()` - Shallow clone with auto-pull and force refresh
+  - `find_configs()` - Recursive *.json discovery (excludes .git)
+  - `get_config()` - Load config with case-insensitive matching
+  - `inject_token()` - Convert SSH to HTTPS with token authentication
+  - `validate_git_url()` - Support HTTPS, SSH, and file:// URLs
+  - Comprehensive error handling (auth failures, missing repos, corrupted caches)
+
+- **SourceManager class** (`src/skill_seekers/mcp/source_manager.py`, 260 lines)
+  - `add_source()` - Register/update sources with validation
+  - `get_source()` - Retrieve by name with helpful errors
+  - `list_sources()` - List all/enabled sources sorted by priority
+  - `remove_source()` - Unregister sources
+  - `update_source()` - Modify specific fields
+  - Atomic file I/O (write to temp, then rename)
+  - Auto-detect token env vars from source type
+
+#### Storage & Caching
+- **Registry file**: `~/.skill-seekers/sources.json`
+  - Stores source metadata (URL, branch, priority, timestamps)
+  - Version-controlled schema (v1.0)
+  - Atomic writes prevent corruption
+
+- **Cache directory**: `$SKILL_SEEKERS_CACHE_DIR` (default: `~/.skill-seekers/cache/`)
+  - One subdirectory per source
+  - Shallow git clones (depth=1, single-branch)
+  - Configurable via environment variable
+
+#### Documentation

+  - `tests/test_git_repo.py` (35 tests) - GitConfigRepo functionality
+    - Initialization, URL validation, token injection
+    - Clone/pull operations, config discovery, error handling
+  - `tests/test_source_manager.py` (48 tests) - SourceManager functionality
+    - Add/get/list/remove/update sources
+    - Registry persistence, atomic writes, default token env
+  - `tests/test_mcp_git_sources.py` (18 tests) - MCP integration
+    - All 3 fetch modes (API, Git URL, Named Source)
+    - Source management tools (add/list/remove)
+    - Complete workflow (add → fetch → remove)
+    - Error scenarios (auth failures, missing configs)
+
+### Improved
+- **MCP server** - Now supports 12 tools (up from 9)
+  - Maintains backward compatibility
+  - Enhanced error messages with available sources
+  - Priority-based config resolution
+
+### Use Cases
+
+**Small Teams (3-5 people):**
+```bash
+# One-time setup
+add_config_source(name="team", git_url="https://github.com/myteam/configs.git")
+
+# Daily usage
+fetch_config(source="team", config_name="react-internal")
+```
+
+**Enterprise (500+ developers):**
+```bash
+# IT pre-configures sources
+add_config_source(name="platform", ..., priority=1)
+add_config_source(name="mobile", ..., priority=2)
+
+# Developers use transparently
+fetch_config(config_name="platform-api")  # Finds in platform source
+```
+
+**Example Repository:**
+```bash
+cd /path/to/Skill_Seekers
+python3 configs/example-team/test_e2e.py  # Test E2E workflow
+```
+
+### Backward Compatibility
+- ✅ All existing configs work unchanged
+- ✅ API mode still default (no registration needed)
+- ✅ No breaking changes to MCP tools or CLI
+- ✅ New parameters are optional (git_url, source, refresh)
+
+### Security
+- ✅ Tokens via environment variables only (not in files)
+- ✅ Shallow clones minimize attack surface
+- ✅ No token storage in registry file
+- ✅ Secure token injection (auto-converts SSH to HTTPS)
+
+### Performance
+- ✅ Shallow clone: 10-50x faster than full clone
+- ✅ Minimal disk space (no git history)
+- ✅ Auto-pull: Only fetches changes (not full re-clone)
+- ✅ Offline mode: Works with cached repos
+
+### Files Changed
+- Modified (2): `pyproject.toml`, `src/skill_seekers/mcp/server.py`
+- Added (6): 3 source files + 3 test files + 1 doc + 1 example repo
+- Total lines added: ~2,600
+
+### Migration Guide
+
+No migration needed! This is purely additive:
+
+```python
+# Before v2.2.0 (still works)
+fetch_config(config_name="react")
+
+# New in v2.2.0 (optional)
+add_config_source(name="team", git_url="...")
+fetch_config(source="team", config_name="react-custom")
+```
+
+### Known Limitations
+- MCP async tests require pytest-asyncio (added to dev dependencies)
+- Example repository uses 'master' branch (git init default)
+
+### See Also

+### Private Config Repositories (**NEW - v2.2.0**)
+
+**The Problem:** Teams need to share custom configs for internal documentation, but don't want to publish them publicly.
+
+**The Solution:** Register private git repositories as config sources. Fetch configs from team repos just like the public API, with full authentication support.
+
+```bash
+# Setup: Set your GitHub token (one-time)
+export GITHUB_TOKEN=ghp_your_token_here
+
+# Option 1: Using MCP tools (recommended)
+# Register your team's private repo
+add_config_source(
+    name="team",
+    git_url="https://github.com/mycompany/skill-configs.git",
+    token_env="GITHUB_TOKEN"
+)
+
+# Fetch config from team repo
+fetch_config(source="team", config_name="internal-api")
+
+# List all registered sources
+list_config_sources()
+
+# Remove source when no longer needed
+remove_config_source(name="team")
+```
+
+**Direct Git URL mode** (no registration):
+```bash
+# Fetch directly from git URL
+fetch_config(
+    git_url="https://github.com/mycompany/configs.git",
+    config_name="react-custom",
+    token="ghp_your_token_here"
+)
+```
+
+**Supported Platforms:**
+- GitHub (token env: `GITHUB_TOKEN`)
+- GitLab (token env: `GITLAB_TOKEN`)
+- Gitea (token env: `GITEA_TOKEN`)
+- Bitbucket (token env: `BITBUCKET_TOKEN`)
+- Any git server (token env: `GIT_TOKEN`)
+
+**Use Cases:**
+
+📋 **Small Teams (3-5 people)**
+```bash
+# Team lead creates repo
+gh repo create myteam/skill-configs --private
+
+# Add configs to repo
+cd myteam-skill-configs
+cp ../Skill_Seekers/configs/react.json ./react-custom.json
+# Edit selectors, categories for your internal docs...
+git add . && git commit -m "Add custom React config" && git push
+
+# Team members register (one-time)
+add_config_source(name="team", git_url="https://github.com/myteam/skill-configs.git")
+
+# Everyone can now fetch
+fetch_config(source="team", config_name="react-custom")
+```
+
+🏢 **Enterprise (500+ developers)**
+```bash
+# IT pre-configures sources for everyone
+add_config_source(name="platform", git_url="gitlab.company.com/platform/configs", priority=1)
+add_config_source(name="mobile", git_url="gitlab.company.com/mobile/configs", priority=2)
+add_config_source(name="official", git_url="api.skillseekersweb.com", priority=3)
+
+# Developers use transparently
+fetch_config(config_name="internal-platform")  # Finds in platform source
+fetch_config(config_name="react")              # Falls back to official API
+```
+
+**Storage Locations:**
+- Registry: `~/.skill-seekers/sources.json`
+- Cache: `$SKILL_SEEKERS_CACHE_DIR` (default: `~/.skill-seekers/cache/`)
+
+**Features:**
+- ✅ **Shallow clone** - 10-50x faster, minimal disk space
+- ✅ **Auto-pull** - Fetches latest changes automatically
+- ✅ **Offline mode** - Works with cached repos when offline
+- ✅ **Priority resolution** - Multiple sources with conflict resolution
+- ✅ **Secure** - Tokens via environment variables only
+
+**Example Team Repository:**
+
+Try the included example:
+```bash
+# Test with file:// URL (no auth needed)
+cd /path/to/Skill_Seekers
+
+# Run the E2E test
+python3 configs/example-team/test_e2e.py
+
+# Or test manually
+add_config_source(
+    name="example",
+    git_url="file://$(pwd)/configs/example-team",
+    branch="master"
+)
+
+fetch_config(source="example", config_name="react-custom")
+```

+# Example Team Config Repository
+
+This is an **example config repository** demonstrating how teams can share custom configs via git.
+
+## Purpose
+
+This repository shows how to:
+- Structure a custom config repository
+- Share team-specific documentation configs
+- Use git-based config sources with Skill Seekers
+
+## Structure
+
+```
+example-team/
+├── README.md           # This file
+├── react-custom.json   # Custom React config (modified selectors)
+├── vue-internal.json   # Internal Vue docs config
+└── company-api.json    # Company API documentation config
+```
+
+## Usage with Skill Seekers
+
+### Option 1: Use this repo directly (for testing)
+
+```python
+# Using MCP tools (recommended)
+add_config_source(
+    name="example-team",
+    git_url="file:///path/to/Skill_Seekers/configs/example-team"
+)
+
+fetch_config(source="example-team", config_name="react-custom")
+```
+
+### Option 2: Create your own team repo
+
+```bash
+# 1. Create new repo
+mkdir my-team-configs
+cd my-team-configs
+git init
+
+# 2. Add configs
+cp /path/to/configs/react.json ./react-custom.json
+# Edit configs as needed...
+
+# 3. Commit and push
+git add .
+git commit -m "Initial team configs"
+git remote add origin https://github.com/myorg/team-configs.git
+git push -u origin main
+
+# 4. Register with Skill Seekers
+add_config_source(
+    name="team",
+    git_url="https://github.com/myorg/team-configs.git",
+    token_env="GITHUB_TOKEN"
+)
+
+# 5. Use it
+fetch_config(source="team", config_name="react-custom")
+```
+
+## Config Naming Best Practices
+
+- Use descriptive names: `react-custom.json`, `vue-internal.json`
+- Avoid name conflicts with official configs
+- Include version if needed: `api-v2.json`
+- Group by category: `frontend/`, `backend/`, `mobile/`
+
+## Private Repositories
+
+For private repos, set the appropriate token environment variable:
+
+```bash
+# GitHub
+export GITHUB_TOKEN=ghp_xxxxxxxxxxxxx
+
+# GitLab
+export GITLAB_TOKEN=glpat-xxxxxxxxxxxxx
+
+# Bitbucket
+export BITBUCKET_TOKEN=xxxxxxxxxxxxx
+```
+
+Then register the source:
+
+```python
+add_config_source(
+    name="private-team",
+    git_url="https://github.com/myorg/private-configs.git",
+    source_type="github",
+    token_env="GITHUB_TOKEN"
+)
+```
+
+## Testing This Example
+
+```bash
+# From Skill_Seekers root directory
+cd /mnt/1ece809a-2821-4f10-aecb-fcdf34760c0b/Git/Skill_Seekers
+
+# Test with file:// URL (no auth needed)
+python3 -c "
+from skill_seekers.mcp.source_manager import SourceManager
+from skill_seekers.mcp.git_repo import GitConfigRepo
+
+# Add source
+sm = SourceManager()
+sm.add_source(
+    name='example-team',
+    git_url='file://$(pwd)/configs/example-team',
+    branch='main'
+)
+
+# Clone and fetch config
+gr = GitConfigRepo()
+repo_path = gr.clone_or_pull('example-team', 'file://$(pwd)/configs/example-team')
+config = gr.get_config(repo_path, 'react-custom')
+print(f'✅ Loaded config: {config[\"name\"]}')
+"
+```

+
+---
+
+## Overview
+
+### What is this feature?
+
+Git-based config sources allow you to fetch config files from **private/team git repositories** in addition to the public API. This unlocks:
+
+- 🔐 **Private configs** - Company/internal documentation
+- 👥 **Team collaboration** - Share configs across 3-5 person teams
+- 🏢 **Enterprise scale** - Support 500+ developers
+- 📦 **Custom collections** - Curated config repositories
+- 🌐 **Decentralized** - Like npm (public + private registries)
+
+### How it works
+
+```
+User → fetch_config(source="team", config_name="react-custom")
+    ↓
+SourceManager (~/.skill-seekers/sources.json)
+    ↓
+GitConfigRepo (clone/pull with GitPython)
+    ↓
+Local cache (~/.skill-seekers/cache/team/)
+    ↓
+Config JSON returned
+```
+
+### Three modes
+
+1. **API Mode** (existing, unchanged)
+   - `fetch_config(config_name="react")`
+   - Fetches from api.skillseekersweb.com
+
+2. **Source Mode** (NEW - recommended)
+   - `fetch_config(source="team", config_name="react-custom")`
+   - Uses registered git source
+
+3. **Git URL Mode** (NEW - one-time)
+   - `fetch_config(git_url="https://...", config_name="react-custom")`
+   - Direct clone without registration
+
+---
+
+## Quick Start
+
+### 1. Set up authentication
+
+```bash
+# GitHub
+export GITHUB_TOKEN=ghp_your_token_here
+
+# GitLab
+export GITLAB_TOKEN=glpat_your_token_here
+
+# Bitbucket
+export BITBUCKET_TOKEN=your_token_here
+```
+
+### 2. Register a source
+
+Using MCP tools (recommended):
+
+```python
+add_config_source(
+    name="team",
+    git_url="https://github.com/mycompany/skill-configs.git",
+    source_type="github",  # Optional, auto-detected
+    token_env="GITHUB_TOKEN",  # Optional, auto-detected
+    branch="main",  # Optional, default: "main"
+    priority=100  # Optional, lower = higher priority
+)
+```
+
+### 3. Fetch configs
+
+```python
+# From registered source
+fetch_config(source="team", config_name="react-custom")
+
+# List available sources
+list_config_sources()
+
+# Remove when done
+remove_config_source(name="team")
+```
+
+### 4. Quick test with example repository
+
+```bash
+cd /path/to/Skill_Seekers
+
+# Run E2E test
+python3 configs/example-team/test_e2e.py
+
+# Or test manually
+add_config_source(
+    name="example",
+    git_url="file://$(pwd)/configs/example-team",
+    branch="master"
+)
+
+fetch_config(source="example", config_name="react-custom")
+```
+
+---
+
+## Architecture
+
+### Storage Locations
+
+**Sources Registry:**
+```
+~/.skill-seekers/sources.json
+```
+
+Example content:
+```json
+{
+  "version": "1.0",
+  "sources": [
+    {
+      "name": "team",
+      "git_url": "https://github.com/myorg/configs.git",
+      "type": "github",
+      "token_env": "GITHUB_TOKEN",
+      "branch": "main",
+      "enabled": true,
+      "priority": 1,
+      "added_at": "2025-12-21T10:00:00Z",
+      "updated_at": "2025-12-21T10:00:00Z"
+    }
+  ]
+}
+```
+
+**Cache Directory:**
+```
+$SKILL_SEEKERS_CACHE_DIR  (default: ~/.skill-seekers/cache/)
+```
+
+Structure:
+```
+~/.skill-seekers/
+├── sources.json       # Source registry
+└── cache/             # Git clones
+    ├── team/          # One directory per source
+    │   ├── .git/
+    │   ├── react-custom.json
+    │   └── vue-internal.json
+    └── company/
+        ├── .git/
+        └── internal-api.json
+```
+
+### Git Strategy
+
+- **Shallow clone**: `git clone --depth 1 --single-branch`
+  - 10-50x faster
+  - Minimal disk space
+  - No history, just latest commit
+
+- **Auto-pull**: Updates cache automatically
+  - Checks for changes on each fetch
+  - Use `refresh=true` to force re-clone
+
+- **Config discovery**: Recursively scans for `*.json` files
+  - No hardcoded paths
+  - Flexible repository structure
+  - Excludes `.git` directory
+
+---
+
+## MCP Tools Reference
+
+### add_config_source
+
+Register a git repository as a config source.
+
+**Parameters:**
+- `name` (required): Source identifier (lowercase, alphanumeric, hyphens/underscores)

+  🔑 Token: GITLAB_TOKEN | ⚡ Priority: 2
+  🕒 Added: 2025-12-21 11:00:00
+```
+
+### remove_config_source
+
+Remove a registered config source.
+
+**Parameters:**
+- `name` (required): Source identifier
+
+**Returns:**
+- Success/failure message
+
+**Note:** Does NOT delete cached git repository data. To free disk space, manually delete `~/.skill-seekers/cache/{source_name}/`
+
+**Example:**
+
+```python
+remove_config_source(name="team")
+```
+
+### fetch_config
+
+Fetch config from API, git URL, or named source.
+
+**Mode 1: Named Source (highest priority)**
+
+```python
+fetch_config(
+    source="team",  # Use registered source
+    config_name="react-custom",
+    destination="configs/",  # Optional
+    branch="main",  # Optional, overrides source default
+    refresh=false  # Optional, force re-clone
+)
+```
+
+**Mode 2: Direct Git URL**
+
+```python
+fetch_config(
+    git_url="https://github.com/myorg/configs.git",
+    config_name="react-custom",
+    branch="main",  # Optional
+    token="ghp_token",  # Optional, prefer env vars
+    destination="configs/",  # Optional
+    refresh=false  # Optional
+)
+```
+
+**Mode 3: API (existing, unchanged)**
+
+```python
+fetch_config(
+    config_name="react",
+    destination="configs/"  # Optional
+)
+
+# Or list available
+fetch_config(list_available=true)
+```
+
+---
+
+## Authentication
+
+### Environment Variables Only
+
+Tokens are **ONLY** stored in environment variables. This is:
+- ✅ **Secure** - Not in files, not in git
+- ✅ **Standard** - Same as GitHub CLI, Docker, etc.
+- ✅ **Temporary** - Cleared on logout
+- ✅ **Flexible** - Different tokens for different services
+
+### Creating Tokens
+
+**GitHub:**
+1. Go to https://github.com/settings/tokens
+2. Generate new token (classic)
+3. Select scopes: `repo` (for private repos)
+4. Copy token: `ghp_xxxxxxxxxxxxx`
+5. Export: `export GITHUB_TOKEN=ghp_xxxxxxxxxxxxx`
+
+**GitLab:**
+1. Go to https://gitlab.com/-/profile/personal_access_tokens
+2. Create token with `read_repository` scope
+3. Copy token: `glpat-xxxxxxxxxxxxx`
+4. Export: `export GITLAB_TOKEN=glpat-xxxxxxxxxxxxx`
+
+**Bitbucket:**
+1. Go to https://bitbucket.org/account/settings/app-passwords/
+2. Create app password with `Repositories: Read` permission
+3. Copy password
+4. Export: `export BITBUCKET_TOKEN=your_password`
+
+### Persistent Tokens
+
+Add to your shell profile (`~/.bashrc`, `~/.zshrc`, etc.):
+
+```bash
+# GitHub token
+export GITHUB_TOKEN=ghp_xxxxxxxxxxxxx
+
+# GitLab token
+export GITLAB_TOKEN=glpat-xxxxxxxxxxxxx
+
+# Company GitLab (separate token)
+export GITLAB_COMPANY_TOKEN=glpat-yyyyyyyyyyyyy
+```
+
+Then: `source ~/.bashrc`
+
+### Token Injection
+
+GitConfigRepo automatically:
+1. Converts SSH URLs to HTTPS
+2. Injects token into URL
+3. Uses token for authentication
+
+**Example:**
+- Input: `git@github.com:myorg/repo.git` + token `ghp_xxx`
+- Output: `https://ghp_xxx@github.com/myorg/repo.git`
+
+---
+
+## Use Cases
+
+### Small Team (3-5 people)
+
+**Scenario:** Frontend team needs custom React configs for internal docs.
+
+**Setup:**
+
+```bash
+# 1. Team lead creates repo
+gh repo create myteam/skill-configs --private
+
+# 2. Add configs
+cd myteam-skill-configs
+cp ../Skill_Seekers/configs/react.json ./react-internal.json
+
+# Edit for internal docs:
+# - Change base_url to internal docs site
+# - Adjust selectors for company theme
+# - Customize categories
+
+git add . && git commit -m "Add internal React config" && git push
+
+# 3. Team members register (one-time)
+export GITHUB_TOKEN=ghp_their_token
+add_config_source(
+    name="team",
+    git_url="https://github.com/myteam/skill-configs.git"
+)
+
+# 4. Daily usage
+fetch_config(source="team", config_name="react-internal")
+```
+
+**Benefits:**
+- ✅ Shared configs across team
+- ✅ Version controlled
+- ✅ Private to company
+- ✅ Easy updates (git push)
+
+### Enterprise (500+ developers)
+
+**Scenario:** Large company with multiple teams, internal docs, and priority-based config resolution.
+
+**Setup:**
+
+```bash
+# IT pre-configures sources for all developers
+# (via company setup script or documentation)
+
+# 1. Platform team configs (highest priority)
+add_config_source(
+    name="platform",
+    git_url="https://gitlab.company.com/platform/skill-configs.git",
+    source_type="gitlab",
+    token_env="GITLAB_COMPANY_TOKEN",
+    priority=1
+)
+
+# 2. Mobile team configs
+add_config_source(
+    name="mobile",
+    git_url="https://gitlab.company.com/mobile/skill-configs.git",
+    source_type="gitlab",
+    token_env="GITLAB_COMPANY_TOKEN",
+    priority=2
+)
+
+# 3. Public/official configs (fallback)
+# (API mode, no registration needed, lowest priority)
+```
+
+**Developer usage:**
+
+```python
+# Automatically finds config with highest priority
+fetch_config(config_name="platform-api")  # Found in platform source
+fetch_config(config_name="react-native")  # Found in mobile source
+fetch_config(config_name="react")  # Falls back to public API
+```
+
+**Benefits:**
+- ✅ Centralized config management
+- ✅ Team-specific overrides
+- ✅ Fallback to public configs
+- ✅ Priority-based resolution
+- ✅ Scales to hundreds of developers
+
+### Open Source Project
+
+**Scenario:** Open source project wants curated configs for contributors.
+
+**Setup:**
+
+```bash
+# 1. Create public repo
+gh repo create myproject/skill-configs --public
+
+# 2. Add configs for project stack
+- react.json (frontend)
+- django.json (backend)
+- postgres.json (database)
+- nginx.json (deployment)
+
+# 3. Contributors use directly (no token needed for public repos)
+add_config_source(
+    name="myproject",
+    git_url="https://github.com/myproject/skill-configs.git"
+)
+
+fetch_config(source="myproject", config_name="react")
+```
+
+**Benefits:**
+- ✅ Curated configs for project
+- ✅ No API dependency
+- ✅ Community contributions via PR
+- ✅ Version controlled
+
+---
+
+## Best Practices
+
+### Config Naming
+
+**Good:**
+- `react-internal.json` - Clear purpose
+- `api-v2.json` - Version included
+- `platform-auth.json` - Specific topic
+
+**Bad:**
+- `config1.json` - Generic
+- `react.json` - Conflicts with official
+- `test.json` - Not descriptive
+
+### Repository Structure
+
+**Flat (recommended for small repos):**
+```
+skill-configs/
+├── README.md
+├── react-internal.json
+├── vue-internal.json
+└── api-v2.json
+```
+
+**Organized (recommended for large repos):**
+```
+skill-configs/
+├── README.md
+├── frontend/
+│   ├── react-internal.json
+│   └── vue-internal.json
+├── backend/
+│   ├── django-api.json
+│   └── fastapi-platform.json
+└── mobile/
+    ├── react-native.json
+    └── flutter.json
+```
+
+**Note:** Config discovery works recursively, so both structures work!
+
+### Source Priorities
+
+Lower number = higher priority. Use sensible defaults:
+
+- `1-10`: Critical/override configs
+- `50-100`: Team configs (default: 100)
+- `1000+`: Fallback/experimental
+
+**Example:**
+```python
+# Override official React config with internal version
+add_config_source(name="team", ..., priority=1)  # Checked first
+# Official API is checked last (priority: infinity)
+```
+
+### Security
+
+✅ **DO:**
+- Use environment variables for tokens
+- Use private repos for sensitive configs
+- Rotate tokens regularly
+- Use fine-grained tokens (read-only if possible)
+
+❌ **DON'T:**
+- Commit tokens to git
+- Share tokens between people
+- Use personal tokens for teams (use service accounts)
+- Store tokens in config files
+
+### Maintenance
+
+**Regular tasks:**
+```bash
+# Update configs in repo
+cd myteam-skill-configs
+# Edit configs...
+git commit -m "Update React config" && git push
+
+# Developers get updates automatically on next fetch
+fetch_config(source="team", config_name="react-internal")
+# ^--- Auto-pulls latest changes
+```
+
+**Force refresh:**
+```python
+# Delete cache and re-clone
+fetch_config(source="team", config_name="react-internal", refresh=true)
+```
+
+**Clean up old sources:**
+```bash
+# Remove unused sources
+remove_config_source(name="old-team")
+
+# Free disk space
+rm -rf ~/.skill-seekers/cache/old-team/
+```
+
+---
+
+## Troubleshooting
+
+### Authentication Failures
+
+**Error:** "Authentication failed for https://github.com/org/repo.git"
+
+**Solutions:**
+1. Check token is set:
+   ```bash
+   echo $GITHUB_TOKEN  # Should show token
+   ```
+
+2. Verify token has correct permissions:
+   - GitHub: `repo` scope for private repos
+   - GitLab: `read_repository` scope
+
+3. Check token isn't expired:
+   - Regenerate if needed
+
+4. Try direct access:
+   ```bash
+   git clone https://$GITHUB_TOKEN@github.com/org/repo.git test-clone
+   ```
+
+### Config Not Found
+
+**Error:** "Config 'react' not found in repository. Available configs: django, vue"
+
+**Solutions:**
+1. List available configs:
+   ```python
+   # Shows what's actually in the repo
+   list_config_sources()
+   ```
+
+2. Check config file exists in repo:
+   ```bash
+   # Clone locally and inspect
+   git clone <git_url> temp-inspect
+   find temp-inspect -name "*.json"
+   ```
+
+3. Verify config name (case-insensitive):
+   - `react` matches `React.json` or `react.json`
+
+### Slow Cloning
+
+**Issue:** Repository takes minutes to clone.
+
+**Solutions:**
+1. Shallow clone is already enabled (depth=1)
+
+2. Check repository size:
+   ```bash
+   # See repo size
+   gh repo view owner/repo --json diskUsage
+   ```
+
+3. If very large (>100MB), consider:
+   - Splitting configs into separate repos
+   - Using sparse checkout
+   - Contacting IT to optimize repo
+
+### Cache Issues
+
+**Issue:** Getting old configs even after updating repo.
+
+**Solutions:**
+1. Force refresh:
+   ```python
+   fetch_config(source="team", config_name="react", refresh=true)
+   ```
+
+2. Manual cache clear:
+   ```bash
+   rm -rf ~/.skill-seekers/cache/team/
+   ```
+
+3. Check auto-pull worked:
+   ```bash
+   cd ~/.skill-seekers/cache/team
+   git log -1  # Shows latest commit
+   ```
+
+---
+
+## Advanced Topics
+
+### Multiple Git Accounts
+
+Use different tokens for different repos:
+
+```bash
+# Personal GitHub
+export GITHUB_TOKEN=ghp_personal_xxx
+
+# Work GitHub
+export GITHUB_WORK_TOKEN=ghp_work_yyy
+
+# Company GitLab
+export GITLAB_COMPANY_TOKEN=glpat-zzz
+```
+
+Register with specific tokens:
+```python
+add_config_source(
+    name="personal",
+    git_url="https://github.com/myuser/configs.git",
+    token_env="GITHUB_TOKEN"
+)
+
+add_config_source(
+    name="work",
+    git_url="https://github.com/mycompany/configs.git",
+    token_env="GITHUB_WORK_TOKEN"
+)
+```
+
+### Custom Cache Location
+
+Set custom cache directory:
+
+```bash
+export SKILL_SEEKERS_CACHE_DIR=/mnt/large-disk/skill-seekers-cache
+```
+
+Or pass to GitConfigRepo:
+```python
+from skill_seekers.mcp.git_repo import GitConfigRepo
+
+gr = GitConfigRepo(cache_dir="/custom/path/cache")
+```
+
+### SSH URLs
+
+SSH URLs are automatically converted to HTTPS + token:
+
+```python
+# Input
+add_config_source(
+    name="team",
+    git_url="git@github.com:myorg/configs.git",
+    token_env="GITHUB_TOKEN"
+)
+
+# Internally becomes
+# https://ghp_xxx@github.com/myorg/configs.git
+```
+
+### Priority Resolution
+
+When same config exists in multiple sources:
+
+```python
+add_config_source(name="team", ..., priority=1)     # Checked first
+add_config_source(name="company", ..., priority=2)  # Checked second
+# API mode is checked last (priority: infinity)
+
+fetch_config(config_name="react")
