+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Overview
+
+This is a Neovim configuration based on kickstart.nvim - a single-file starter configuration that prioritizes being small, documented, and understandable. The configuration has been customized with additional plugins and settings.
+
+## Architecture
+
+### Single-File Configuration
+The entire configuration is contained in `init.lua` (lines 1-1001). This is intentional - kickstart.nvim uses a single-file approach as a teaching tool and reference. While splitting into modules is possible, the current structure keeps everything in one place for clarity.
+
+### Plugin Management
+- **Plugin Manager**: lazy.nvim (installed at init.lua:122-130)
+- **Plugin Definitions**: All plugins defined in the `lazy.setup()` call starting at init.lua:143
+- **Custom Plugins**: Additional user plugins can be added in `lua/custom/plugins/init.lua`
+
+### Key Plugin Categories
+
+1. **LSP Configuration** (init.lua:435-698)
+   - Mason for LSP installation (init.lua:454-456)
+   - Configured servers: `pyright`, `zls`, `rust_analyzer`, `ts_ls`, `lua_ls`
+   - LSP capabilities enhanced by blink.cmp (init.lua:624)
+   - Autocommands for LSP attach events setup keymaps and highlighting
+
+2. **Completion** (init.lua:746-837)
+   - blink.cmp for autocompletion
+   - LuaSnip for snippet expansion
+   - Default keymap preset uses `<c-y>` to accept
+
+3. **Telescope** (init.lua:255-359)
+   - Fuzzy finder with vertical layout
+   - Extensions: fzf, ui-select
+   - Leader-based keymaps for searching files, grep, diagnostics, etc.
+
+4. **Navigation & Movement**
+   - Harpoon2 for file bookmarking (init.lua:375-432)
+   - Flash.nvim for rapid cursor movement (init.lua:361-373)
+   - Oil.nvim for file browsing (init.lua:964-978)
+   - vim-tmux-navigator for seamless tmux/vim navigation (init.lua:154-170)
+
+5. **Formatting** (init.lua:701-744)
+   - conform.nvim handles formatting
+   - Format on save enabled (except for C/C++)
+   - Configured formatters: stylua (Lua), prettier (JS/TS/CSS/HTML/JSON)
+

+
+## Configuration Details
+
+### Settings
+- Leader key: `<space>` (init.lua:2)
+- Line numbers: relative + absolute (init.lua:9-10)
+- No line wrapping (init.lua:19)
+- Clipboard: synced with OS (init.lua:21-23)
+- Undo history: persisted (init.lua:29)
+- Scrolloff: 10 lines (init.lua:61)
+- Cursor: blinking block in normal mode, vertical bar in insert (init.lua:68-72)
+
+### Treesitter Languages
+Auto-installed parsers for: zig, python, typescript, rust, htmldjango, bash, c, html, lua, markdown, vim (init.lua:912-929)
+
+### Color Scheme
+Currently using kanso.nvim (init.lua:848-856). Several commented-out alternatives available (gruvbox-material, catppuccin, kanagawa, zenbones, vague).
+
+### Custom Keymaps
+- `<C-d>/<C-u>`: Page down/up with recentering (init.lua:76-77)
+- `<C-h/j/k/l>`: Window navigation (init.lua:98-101)
+- `<Esc>`: Clear search highlights (init.lua:81)
+
+## Development Notes
+
+### Modifying Configuration
+The main configuration is in `init.lua`. When making changes:
+1. Restart Neovim or `:source $MYVIMRC`
+2. Run `:Lazy sync` if plugins were added/removed
+3. Run `:Mason` to install new LSP servers or formatters
+
+### Adding New LSP Servers
+1. Add server to the `servers` table (init.lua:635-663)
+2. Add to `ensure_installed` if needed (init.lua:678-681)
+3. Restart Neovim - mason-tool-installer will auto-install
+
+### Adding Formatters
+1. Install via Mason or ensure it's in PATH
+2. Add to `formatters_by_ft` table (init.lua:731-742)
+3. Optionally add to `ensure_installed` (init.lua:679)
+
+### Plugin Organization
+- Custom user plugins: Add to `lua/custom/plugins/init.lua` or create new files in that directory
+- Kickstart example plugins: Located in `lua/kickstart/plugins/` (currently commented out/unused)
