- Add --create-github-repos flag to automatically create missing GitHub repositories
- Implement GitHub API client with token support from config/env/file
- Add Codeberg API integration to sync all public repositories

+# GitSyncer
+
+GitSyncer is a tool for synchronizing git repositories between multiple organizations (e.g., GitHub and Codeberg). It automatically keeps all branches in sync across different git hosting platforms.
+
+## Features
+
+- Sync repositories between multiple git organizations
+- Automatic branch creation on remotes that don't have them
+- Batch sync multiple repositories with a single command
+- Sync all public repositories from Codeberg to other platforms
+- Merge conflict detection
+- Never deletes branches (only adds/updates)
+
+## Installation
+
+```bash
+go build -o gitsyncer ./cmd/gitsyncer
+```
+
+## Configuration
+
+Create a `gitsyncer.json` file:
+
+```json
+{
+  "organizations": [
+    {
+      "host": "git@codeberg.org",
+      "name": "yourusername"
+    },
+    {
+      "host": "git@github.com",
+      "name": "yourusername"
+    }
+  ],
+  "repositories": [
+    "repo1",
+    "repo2"
+  ]
+}
+```
+
+## Usage
+
+### Sync a single repository
+```bash
+./gitsyncer --sync repo-name
+```
+
+### Sync all configured repositories
+```bash
+./gitsyncer --sync-all
+```
+
+### Sync all public Codeberg repositories
+```bash
+# Dry run - see what would be synced
+./gitsyncer --sync-codeberg-public --dry-run
+
+# Actually sync all public repos
+./gitsyncer --sync-codeberg-public
+```
+
+### List configured organizations
+```bash
+./gitsyncer --list-orgs
+```
+
+### List configured repositories  
+```bash
+./gitsyncer --list-repos
+```
+
+### Show version
+```bash
+./gitsyncer --version
+```
+
+## How It Works
+
+1. GitSyncer clones the repository from the first configured organization
+2. Adds all other organizations as git remotes
+3. For each branch:
+   - Fetches from all remotes
+   - Merges changes from remotes that have the branch
+   - Pushes to all remotes (creating branches if needed)
+
+## Example Workflows
+
+### Sync specific repositories
+1. Create repositories on all platforms (GitHub, Codeberg, etc.)
+2. Add the repository name to your `gitsyncer.json`
+3. Run `./gitsyncer --sync repo-name`
+4. GitSyncer will:
+   - Clone from the first organization
+   - Push all branches to other organizations
+   - Keep them in sync going forward
+
+### Sync all public Codeberg repositories
+1. Ensure Codeberg is in your organizations list
+2. Run `./gitsyncer --sync-codeberg-public`
+3. GitSyncer will:
+   - Fetch all public repositories from your Codeberg account
+   - Sync each one to all other configured organizations
+   - Skip any that fail (e.g., don't exist on other platforms)
+
+## Error Handling
+
+- **Merge conflicts**: GitSyncer will detect conflicts and exit with an error message
+- **Missing repositories**: Must be created manually on all platforms
+- **Missing branches**: Automatically created on remotes that don't have them
