+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Overview
+
+This is a nixvim configuration repository that provides a standalone Neovim configuration using Nix flakes. The configuration is built using the nixvim framework, which allows declarative Neovim configuration through Nix expressions.
+
+## Development Commands
+
+### Testing Configuration
+```bash
+# Test the current configuration by running nixvim
+nix run .
+
+# Verify configuration is not broken
+nix flake check .
+```
+
+### Installation
+```bash
+# Install the configuration to user profile (first time)
+./install.sh
+# or manually:
+nix profile install .
+
+# Update existing installation
+./update.sh
+```
+
+### Git Workflow Scripts
+```bash
+# Switch to dev branch and pull latest changes
+./pull.sh
+
+# Commit changes with timestamp, merge to main, and push
+./push.sh
+```
+
+## Architecture
+
+### Core Structure
+- **flake.nix**: Main flake definition with nixpkgs, nixvim, and flake-parts inputs
+- **config/**: Contains all nixvim configuration modules
+  - **default.nix**: Main configuration file with plugins, options, and keymaps
+  - **bufferline.nix**: Example modular configuration for bufferline plugin
+- **flake.lock**: Dependency lockfile
+
+### Configuration System
+The configuration uses nixvim's module system:
+- Configurations are split into logical modules in the `config/` directory
+- Each module can be imported in `config/default.nix`
+- The main configuration includes essential plugins like Telescope, LSP support, Treesitter, and various productivity tools
+
+### Key Features Enabled
+- Nord colorscheme with line numbers and relative numbering
+- Comprehensive plugin suite including Telescope, nvim-tree, fugitive, lazygit
+- Auto-completion with cmp and all sources enabled
+- Custom keymap for hop (two-character jump) on 's' key
+- Tab width set to 2 spaces
+
+### Branch Strategy
+- **main**: Stable configuration
+- **dev**: Development branch for testing changes
+- Scripts automate switching and merging between branches
+
+## Adding New Configurations
+
+1. Create new `.nix` files in the `config/` directory for specific feature sets
+2. Import them in `config/default.nix` using the imports array
+3. Test with `nix run .` before committing
+4. Use the git workflow scripts to maintain the branch structure

-# Nixvim template
+# Nixvim Configuration
 
-This template gives you a good starting point for configuring nixvim standalone.
+A standalone Neovim configuration built with [nixvim](https://github.com/nix-community/nixvim) and Nix flakes.
+
+## Installation
+
+```bash
+# First time — install to your Nix profile
+./install.sh
+
+# Update an existing installation
+./update.sh
+```
+
+## Testing your configuration
+
+```bash
+# Try the config without installing
+nix run .
+
+# Verify nothing is broken
+nix flake check .
+```
 
 ## Configuring
 
-To start configuring, just add or modify the nix files in `./config`.
-If you add a new configuration file, remember to add it to the
-[`config/default.nix`](./config/default.nix) file
+Add or modify nix files in `./config`. The main entry point is [`config/default.nix`](./config/default.nix).
 
-## Testing your new configuration
+## Plugin Usage Guide
 
-To test your configuration simply run the following command
+This configuration comes with a curated set of plugins. Here's how to get the most out of each one.
 
-```
-nix run .
-```
+### Navigation
+
+#### Telescope — fuzzy finder for everything
+| Keymap | Action |
+|---|---|
+| `<leader>ff` | Find files in the project |
+| `<leader>fg` | Live grep across all files (uses ripgrep) |
+| `<leader>fb` | Browse open buffers |
+| `<leader>fh` | Search help tags |
+
+Type to filter results, `<CR>` to open, `<C-x>` to open in a split, `<C-v>` for a vertical split.
+
+#### Hop — jump to any visible position
+| Keymap | Action |
+|---|---|
+| `s` + two characters | Jump to any matching two-character sequence on screen |
+
+Press `s`, type two characters, then press the hint letter to jump there instantly. Much faster than `f`/`F` or `/search` for medium-distance jumps.
+
+#### fzf-lua — alternative fuzzy finder
+| Command | Action |
+|---|---|
+| `:FzfLua files` | Find files |
+| `:FzfLua grep` | Grep project |
+| `:FzfLua buffers` | Switch buffers |
+
+Faster than Telescope on very large codebases thanks to the native fzf algorithm.
+
+### File Management
+
+#### nvim-tree — sidebar file explorer
+| Keymap | Action |
+|---|---|
+| `<C-n>` or `:NvimTreeToggle` | Toggle the file tree sidebar |
+| `a` | Create a new file or directory (inside the tree) |
+| `d` | Delete file (inside the tree) |
+| `r` | Rename file (inside the tree) |
+| `<CR>` | Open file or expand folder |
+
+#### Oil — edit the filesystem like a buffer
+| Command | Action |
+|---|---|
+| `:Oil` | Open the parent directory as an editable buffer |
+
+Rename files by editing their names, delete by removing lines, create by adding new lines. Save the buffer (`:w`) to apply changes.
+
+#### Bufferline — tab-style buffer bar
+| Keymap | Action |
+|---|---|
+| `:bnext` / `:bprev` | Cycle through open buffers |
+| `:bdelete` | Close the current buffer |
+
+Click on tabs with the mouse or use buffer commands to switch between open files.
+
+### Git
+
+#### Fugitive — Git commands inside Neovim
+| Command | Action |
+|---|---|
+| `:Git` | Open interactive git status (stage with `s`, commit with `cc`) |
+| `:Git blame` | Inline blame annotations for the current file |
+| `:Git diff` | View diff of current file |
+| `:Git log` | Browse commit history |
+| `:Gwrite` | Stage the current file |
+
+#### Lazygit — full git UI in a floating terminal
+| Command | Action |
+|---|---|
+| `:LazyGit` | Open the lazygit terminal UI |
+
+A visual interface for staging, committing, branching, rebasing, and more. Navigate with arrow keys, press `?` inside lazygit for help.
+
+### Editing
+
+#### Commentary — toggle comments
+| Keymap | Action |
+|---|---|
+| `gcc` | Toggle comment on the current line |
+| `gc` + motion | Toggle comments over a motion (e.g. `gcap` for a paragraph) |
+| `gc` in visual mode | Toggle comments on selected lines |
+
+#### vim-surround — manage surrounding characters
+| Keymap | Action |
+|---|---|
+| `cs"'` | Change surrounding `"` to `'` |
+| `ds"` | Delete surrounding `"` |
+| `ysiw]` | Surround the word with `[]` |
+| `S"` in visual mode | Surround selection with `"` |
+
+#### cmp — autocompletion
+Completion popups appear automatically as you type. Use:
+| Keymap | Action |
+|---|---|
+| `<C-n>` / `<C-p>` | Navigate completion items |
+| `<CR>` | Accept the selected completion |
+| `<C-e>` | Dismiss the completion menu |
+
+Sources include buffer words, file paths, LSP, and more (all enabled automatically).
+
+### UI & Visual Aids
+
+#### which-key — keybinding discovery
+Press `<leader>` (or any prefix key) and **wait** — a popup shows all available continuations. Great for learning and remembering mappings you don't use often.
+
+#### indent-blankline — indentation guides
+Visible automatically. Vertical lines show indentation levels so you can quickly see code structure and nesting depth.
+
+#### illuminate — highlight word under cursor
+Automatic — all occurrences of the word under your cursor are highlighted. Helps you quickly spot where a variable or function is used.
+
+#### lualine — statusline
+Always visible at the bottom. Shows the current mode, git branch, filename, file type, cursor position, and diagnostics.
+
+### Terminal & Environment
+
+#### toggleterm — embedded terminal
+| Command | Action |
+|---|---|
+| `:ToggleTerm` | Toggle a persistent terminal at the bottom |
+
+The terminal persists its state between toggles, so running processes stay alive.
+
+#### direnv — automatic environment loading
+Automatic — when you open a project with a `.envrc`, Neovim loads the environment variables and nix shell automatically. No action needed.
+
+### Language Support
+
+#### Treesitter — syntax-aware highlighting
+Automatic — provides accurate syntax highlighting, indentation, and code folding for all supported languages. Much better than regex-based highlighting.
+
+#### Nix — Nix language support
+Automatic — syntax highlighting, error checking, and formatting for `.nix` files.
+
+#### OpenSCAD — 3D modeling language support
+Automatic — syntax highlighting for `.scad` files.
+
+### AI
+
+#### CodeCompanion — AI assistant
+| Command | Action |
+|---|---|
+| `:CodeCompanionChat` | Open an AI chat buffer |
+| `:CodeCompanionActions` | Browse available AI actions |
+
+Use it for inline code suggestions, explanations, and refactoring help directly inside the editor.
