+## Overview
+
+gitx is a keyboard-driven application with customizable keybindings. Every action in gitx can be remapped to your preferred key combination. This guide covers all available keybinds, how to customize them, and best practices for configuring your keyboard shortcuts.
+
+## Configuration
+
+Keybindings are configured in your gitx configuration file located at `~/.config/gitx/config.toml`. The keybindings section uses the following format:
+
+```toml
+[keybindings]
+action_name = "key_combination"
+```
+
+### Key Specification Format
+
+Keys can be specified in several ways:
+
+- **Single keys**: `a`, `1`, `!`, etc.
+- **Special keys**: `enter`, `esc`, `tab`, `space`, `up`, `down`, `left`, `right`, `backspace`, `delete`, `home`, `end`, `pgup`, `pgdn`
+- **Modifier combinations**: `ctrl+c`, `shift+tab`, `alt+x`
+- **Multiple key options**: `q,ctrl+c` (either key will trigger the action)
+
+You can specify multiple alternative keybindings for a single action by separating them with commas.
+
+## Default Keybindings
+
+Here are all the default keybindings organized by category:
+
+### Navigation
+
+| Action | Default Key | Description |
+|--------|-------------|-------------|
+| `focus_next` | `tab` | Move to the next window |

+
+| Action | Default Key | Description |

+| `stash_apply` | `a` | Apply a stash without removing it |
+| `stash_pop` | `p` | Apply a stash and remove it |
+| `stash_drop` | `d` | Delete the selected stash |
+
+### Miscellaneous
+

+| `toggle_help` | `?` | Show/hide the help panel |
+| `escape` | `esc` | Cancel current action |
+| `quit` | `q` or `ctrl+c` | Exit gitx |
+
+## Customizing Keybindings
+
+### Basic Customization
+
+To customize a keybinding, add it to the `[keybindings]` section in your `~/.config/gitx/config.toml` file. For example:
+
+```toml
+[keybindings]
+# Use 'l' instead of 'j' to move down
+down = "l"
+
+# Use 'h' instead of 'k' to move up  
+up = "h"
+
+# Create a new branch with 'b'
+new_branch = "b"
+```
+
+### Multiple Key Options
+
+You can specify multiple keys that trigger the same action by separating them with commas:
+
+```toml
+[keybindings]
+# Stage with either 'a' or 's'
+stage_item = "a,s"
+
+# Quit with 'q', ctrl+c, or ctrl+d
+quit = "q,ctrl+c,ctrl+d"
+
+# Switch themes with ctrl+t or ctrl+n
+switch_theme = "ctrl+t,ctrl+n"
+```
+
+### Vim-like Configuration
+
+Many users prefer vim-like keybindings. Here's a complete vim-inspired configuration:
+
+```toml
+[keybindings]
+# Navigation
+up = "k"
+down = "j"
+left = "h"
+right = "l"
+
+# File operations
+stage_item = "a"
+commit = "c"
+discard = "d"
+stash = "z"
+
+# Branch operations
+new_branch = "b"
+checkout = "o"
+delete_branch = "x"
+rename_branch = "r"
+
+# Commit operations  
+amend_commit = "e"
+revert = "v"
+reset_to_commit = "R"
+
+# General
+toggle_help = "?"
+quit = "q"
+escape = "esc"
+```
+
+### Emacs-like Configuration
+
+For those preferring Emacs-style bindings:
+
+```toml
+[keybindings]
+# Navigation (Ctrl+N/P for next/previous, Ctrl+F/B for forward/backward)
+down = "ctrl+n"
+up = "ctrl+p"
+
+# Word navigation
+focus_next = "ctrl+z"
+focus_prev = "ctrl+shift+z"
+
+# Common operations
+stage_item = "ctrl+a"
+discard = "ctrl+d"
+stash = "ctrl+s"
+commit = "ctrl+x"
+
+# Help and exit
+toggle_help = "ctrl+h"
+quit = "ctrl+c"
+escape = "esc"
+```
+
+### Arrow Key Configuration
+
+If you prefer using arrow keys for navigation:
+
+```toml
+[keybindings]
+# Use arrow keys
+up = "up"
+down = "down"
+left = "left"
+right = "right"
+
+# Keep other keys for actions
+stage_item = "a"
+commit = "c"
+new_branch = "n"
+```
+
+## Advanced Examples
+
+### Minimal Keybinding Set
+
+If you only want to change a few keybindings and keep most defaults:
+
+```toml
+[keybindings]
+# Only customize your most-used actions
+commit = "w"
+stage_item = "s"
+toggle_help = "h"
+```
+
+### Dvorak Layout Configuration
+
+For Dvorak keyboard layout users:
+
+```toml
+[keybindings]
+# Dvorak layout mappings (mapped to QWERTY position)
+up = "o"
+down = "a"
+left = "s"
+right = "e"
+
+# Common operations using Dvorak
+stage_item = "j"
+commit = "b"
+discard = "h"
+new_branch = "c"
+```
+
+### Macros and Complex Workflows
+
+While gitx doesn't support full macro systems, you can use common key combinations for your workflow:
+
+```toml
+[keybindings]
+# Quick workflow keys
+new_branch = "n"
+stage_all = "s"
+commit = "c"
+checkout = "o"
+delete_branch = "x"
+
+# Focus shortcuts
+focus_files = "2"
+focus_branches = "3"
+focus_commits = "4"
+```
+
+## Tips and Best Practices
+
+1. **Avoid Conflicts**: Don't map the same key combination to multiple actions
+2. **Use Modifiers Wisely**: Reserve Ctrl combinations for important actions you use frequently
+3. **Consistency**: Try to keep your keybindings consistent with tools you already use (vim, tmux, etc.)
+4. **Test Before Committing**: After changing a keybinding, test it in gitx to ensure it works
+5. **Document Your Setup**: Keep notes on your custom keybindings for future reference
+6. **Preserve Escape**: It's recommended to keep `escape` bound to `esc` as a safe abort key
+
+## Viewing Active Keybindings
+
+When inside gitx, press `?` (or your custom `toggle_help` key) to view the current active keybindings. This will show all keybindings for the currently focused panel.
+
+## Configuration File Location
+
+Your keybindings are stored in: `~/.config/gitx/config.toml`
+
+If this file doesn't exist, gitx will create it with default settings the first time you run the application.
