+# lua-ls
+
+Lua language server plugin for Claude Code, providing code intelligence features for Lua files.
+
+## Features
+
+| Feature | Description |
+|---------|-------------|
+| **goToDefinition** | Navigate to function and variable definitions |
+| **findReferences** | Find all usages of symbols across your workspace |
+| **hover** | Inline documentation and type information |
+| **diagnostics** | Real-time validation and error checking |
+
+## Supported Files
+
+| Extension | Language ID | Description |
+|-----------|-------------|-------------|
+| `.lua` | `lua` | Lua source files |
+
+## Prerequisites
+
+Requires [lua-language-server](https://github.com/LuaLS/lua-language-server) in your PATH.
+
+```bash
+# macOS / Linux (Homebrew)
+brew install lua-language-server
+
+# See https://github.com/LuaLS/lua-language-server/wiki/Getting-Started for other methods
+```
+
+## Installation
+
+```bash
+# Add marketplace from vnz/cc-plugins (aliased as cc-plugins-vnz)
+/plugin marketplace add vnz/cc-plugins
+
+# Install plugin from the new marketplace
+/plugin install lua-ls@cc-plugins-vnz
+```
+
+Enable LSP in your Claude Code settings (`~/.claude/settings.json`):
+
+```json
+{
+  "env": {
+    "ENABLE_LSP_TOOL": "1"
+  }
+}
+```
+
+## Configuration
+
+lua-language-server reads project settings from `.luarc.json` or `.luarc.jsonc` in your workspace root. Common options:
+
+```json
+{
+  "runtime.version": "LuaJIT",
+  "diagnostics.globals": ["vim"],
+  "workspace.library": ["$VIMRUNTIME"],
+  "workspace.checkThirdParty": false
+}
+```
+
+See the [settings reference](https://github.com/LuaLS/lua-language-server/wiki/Settings) for all options.
+
+## Troubleshooting
+
+### Plugin not visible
+Run `/plugin list` and verify the plugin appears. Try reinstalling if needed.
+
+### LSP not working
+1. Verify lua-language-server is in your PATH: `which lua-language-server`
+2. Check that `ENABLE_LSP_TOOL=1` is set in your settings and restart Claude Code.
+3. Check Claude Code logs for any `lua-language-server` errors.
