+# Nuanced LSP plugin for Claude Code
+
+Plugin to use the Nuanced LSP server with Claude Code.
+
+## Installation
+
+Install Nuanced LSP:
+
+```bash
+npm i -g @nuanced-dev/lsp
+```
+
+Add the Nuanced marketplace and install the plugin:
+
+```bash
+claude plugin marketplace add nuanced-dev/lsp
+claude plugin install lsp@nuanced-dev
+```
+
+Start using the LSP tool in Claude Code.
+
+## Caveats
+
+- The plugin requires that Claude Code is started in the project root, otherwise the LSP workspace will be incorrect.
+
+- Some people report that the LSP tool only works when running Claude Code thropugh NPM, not when using the native binaries.
+
+## More Information
+
+See [@nuanced-dev/lsp](https://www.npmjs.com/package/@nuanced-dev/lsp) package.
