+# Git Interface for Go
+
+A comprehensive Go interface for Git operations that provides a clean, type-safe API for interacting with Git repositories.
+
+## Features
+
+- **Complete Git Operations**: Supports all major Git operations including repository management, commits, branches, remotes, tags, and more
+- **Type-Safe API**: Strongly typed interfaces and structs for better code safety
+- **Context Support**: All operations support context for cancellation and timeouts
+- **Error Handling**: Comprehensive error handling with detailed error messages
+- **Flexible Configuration**: Configurable timeouts and environment variables
+- **Easy to Use**: Simple and intuitive API design
+
+## Installation
+
+The Git interface is part of the `github.com/iomodo/staff` module. No additional dependencies are required beyond the standard library.
+
+## Quick Start
+
+```go
+package main
+
+import (
+    "context"
+    "fmt"
+    "log"
+    
+    "github.com/iomodo/staff/git"
+)
+
+func main() {
+    ctx := context.Background()
+    
+    // Create a Git instance
+    git := git.DefaultGit("/path/to/your/repo")
+    
+    // Open an existing repository
+    if err := git.Open(ctx, "/path/to/your/repo"); err != nil {
+        log.Fatalf("Failed to open repository: %v", err)
+    }
+    
+    // Get repository status
+    status, err := git.Status(ctx)
+    if err != nil {
+        log.Fatalf("Failed to get status: %v", err)
+    }
+    
+    fmt.Printf("Current branch: %s\n", status.Branch)
+    fmt.Printf("Repository is clean: %t\n", status.IsClean)
+}
+```
+
+## Core Interface
+
+### GitInterface
+
+The main interface that defines all Git operations:
+
+```go
+type GitInterface interface {
+    // Repository operations
+    Init(ctx context.Context, path string) error
+    Clone(ctx context.Context, url, path string) error
+    IsRepository(ctx context.Context, path string) (bool, error)
+    
+    // Status and information
+    Status(ctx context.Context) (*Status, error)
+    Log(ctx context.Context, options LogOptions) ([]Commit, error)
+    Show(ctx context.Context, ref string) (*Commit, error)
+    
+    // Branch operations
+    ListBranches(ctx context.Context) ([]Branch, error)
+    CreateBranch(ctx context.Context, name string, startPoint string) error
+    Checkout(ctx context.Context, ref string) error
+    DeleteBranch(ctx context.Context, name string, force bool) error
+    GetCurrentBranch(ctx context.Context) (string, error)
+    
+    // Commit operations
+    Add(ctx context.Context, paths []string) error
+    AddAll(ctx context.Context) error
+    Commit(ctx context.Context, message string, options CommitOptions) error
+    
+    // Remote operations
+    ListRemotes(ctx context.Context) ([]Remote, error)
+    AddRemote(ctx context.Context, name, url string) error
+    RemoveRemote(ctx context.Context, name string) error
+    Fetch(ctx context.Context, remote string, options FetchOptions) error
+    Pull(ctx context.Context, remote, branch string) error
+    Push(ctx context.Context, remote, branch string, options PushOptions) error
+    
+    // Merge operations
+    Merge(ctx context.Context, ref string, options MergeOptions) error
+    MergeBase(ctx context.Context, ref1, ref2 string) (string, error)
+    
+    // Configuration
+    GetConfig(ctx context.Context, key string) (string, error)
+    SetConfig(ctx context.Context, key, value string) error
+    GetUserConfig(ctx context.Context) (*UserConfig, error)
+    SetUserConfig(ctx context.Context, config UserConfig) error
+}
+```
+
+## Data Structures
+
+### Status
+
+Represents the current state of the repository:
+
+```go
+type Status struct {
+    Branch     string
+    IsClean    bool
+    Staged     []FileStatus
+    Unstaged   []FileStatus
+    Untracked  []string
+    Conflicts  []string
+}
+```
+
+### Commit
+
+Represents a Git commit:
+
+```go
+type Commit struct {
+    Hash      string
+    Author    Author
+    Committer Author
+    Message   string
+    Parents   []string
+    Timestamp time.Time
+    Files     []CommitFile
+}
+```
+
+### Branch
+
+Represents a Git branch:
+
+```go
+type Branch struct {
+    Name      string
+    IsCurrent bool
+    IsRemote  bool
+    Commit    string
+    Message   string
+}
+```
+
+## Usage Examples
+
+### Repository Management
+
+```go
+// Initialize a new repository
+git := git.DefaultGit("/path/to/new/repo")
+if err := git.Init(ctx, "/path/to/new/repo"); err != nil {
+    log.Fatal(err)
+}
+
+// Clone a repository
+if err := git.Clone(ctx, "https://github.com/user/repo.git", "/path/to/clone"); err != nil {
+    log.Fatal(err)
+}
+```
+
+### Basic Git Workflow
+
+```go
+// Stage files
+if err := git.Add(ctx, []string{"file1.txt", "file2.txt"}); err != nil {
+    log.Fatal(err)
+}
+
+// Or stage all changes
+if err := git.AddAll(ctx); err != nil {
+    log.Fatal(err)
+}
+
+// Commit changes
+commitOptions := git.CommitOptions{
+    AllowEmpty: false,
+}
+if err := git.Commit(ctx, "Add new feature", commitOptions); err != nil {
+    log.Fatal(err)
+}
+```
+
+### Branch Operations
+
+```go
+// List all branches
+branches, err := git.ListBranches(ctx)
+if err != nil {
+    log.Fatal(err)
+}
+
+for _, branch := range branches {
+    fmt.Printf("Branch: %s (current: %t)\n", branch.Name, branch.IsCurrent)
+}
+
+// Create a new branch
+if err := git.CreateBranch(ctx, "feature/new-feature", ""); err != nil {
+    log.Fatal(err)
+}
+
+// Switch to a branch
+if err := git.Checkout(ctx, "feature/new-feature"); err != nil {
+    log.Fatal(err)
+}
+
+// Get current branch
+currentBranch, err := git.GetCurrentBranch(ctx)
+if err != nil {
+    log.Fatal(err)
+}
+fmt.Printf("Current branch: %s\n", currentBranch)
+```
+
+### Remote Operations
+
+```go
+// Add a remote
+if err := git.AddRemote(ctx, "origin", "https://github.com/user/repo.git"); err != nil {
+    log.Fatal(err)
+}
+
+// List remotes
+remotes, err := git.ListRemotes(ctx)
+if err != nil {
+    log.Fatal(err)
+}
+
+for _, remote := range remotes {
+    fmt.Printf("Remote: %s -> %s\n", remote.Name, remote.URL)
+}
+
+// Fetch from remote
+fetchOptions := git.FetchOptions{
+    All:  true,
+    Tags: true,
+}
+if err := git.Fetch(ctx, "", fetchOptions); err != nil {
+    log.Fatal(err)
+}
+
+// Push to remote
+pushOptions := git.PushOptions{
+    SetUpstream: true,
+}
+if err := git.Push(ctx, "origin", "main", pushOptions); err != nil {
+    log.Fatal(err)
+}
+```
+
+### Configuration
+
+```go
+// Get user configuration
+userConfig, err := git.GetUserConfig(ctx)
+if err != nil {
+    log.Fatal(err)
+}
+fmt.Printf("User: %s <%s>\n", userConfig.Name, userConfig.Email)
+
+// Set user configuration
+newConfig := git.UserConfig{
+    Name:  "John Doe",
+    Email: "john@example.com",
+}
+if err := git.SetUserConfig(ctx, newConfig); err != nil {
+    log.Fatal(err)
+}
+
+// Get/set custom config
+value, err := git.GetConfig(ctx, "core.editor")
+if err != nil {
+    log.Fatal(err)
+}
+
+if err := git.SetConfig(ctx, "core.editor", "vim"); err != nil {
+    log.Fatal(err)
+}
+```
+
+## Error Handling
+
+The Git interface provides detailed error information through the `GitError` type:
+
+```go
+if err := git.Commit(ctx, "Invalid commit", git.CommitOptions{}); err != nil {
+    if gitErr, ok := err.(*git.GitError); ok {
+        fmt.Printf("Git command '%s' failed: %v\n", gitErr.Command, gitErr.Err)
+        fmt.Printf("Output: %s\n", gitErr.Output)
+    }
+}
+```
+
+## Configuration
+
+You can customize the Git instance with specific configuration:
+
+```go
+config := git.GitConfig{
+    Timeout: 60 * time.Second,
+    Env: map[string]string{
+        "GIT_AUTHOR_NAME":  "Custom Author",
+        "GIT_AUTHOR_EMAIL": "author@example.com",
+    },
+}
+
+git := git.NewGit("/path/to/repo", config)
+```
+
+## Thread Safety
+
+The Git interface is not thread-safe. If you need to use it from multiple goroutines, you should either:
+
+1. Use separate Git instances for each goroutine
+2. Use a mutex to synchronize access
+3. Use channels to serialize operations
+
+## Requirements
+
+- Go 1.24.4 or later
+- Git installed and available in PATH
+- Appropriate permissions to access the repository
+
