+# npmx for Zed
+
+This is the in-repo Zed extension for `npmx`. It runs the shared `npmx-language-server`
+over stdio, so Zed gets the same core package intelligence used by the VS Code extension.
+
+## Status
+
+- Uses the shared `npmx-language-server`
+- Targets local development from this monorepo first
+- Defaults to `packages/language-server/dist/index.cjs`
+- Launches the language server over `--stdio`
+- Supports overriding the launched command through Zed `lsp.npmx.binary` settings
+- Forwards `lsp.npmx.settings` to the language server as `npmx` workspace configuration
+
+## Features
+
+- Hover links to package pages and docs on [npmx.dev](https://npmx.dev)
+- Emoji hover icons for non-VS Code editors
+- Version completion with provenance and prerelease settings
+- Diagnostics for upgrades, deprecations, replacements, vulnerabilities, dist tags, and engine mismatches
+- Document links for package names
+- Workspace-aware dependency resolution for npm, pnpm, yarn, and bun projects
+
+## Local Development
+
+1. Build the language server from the repo root with `pnpm build`.
+2. In Zed, install `extensions/zed` as a dev extension.
+3. If you want a custom launch command, configure `lsp.npmx.binary` in your Zed settings.
+
+## Settings
+
+Zed settings under `lsp.npmx.settings` are forwarded directly to the language server.
+Use scoped npmx settings without the leading `npmx.` prefix:
+
+```json
+{
+  "lsp": {
+    "npmx": {
+      "settings": {
+        "hover": {
+          "enabled": true
+        },
+        "completion": {
+          "version": "provenance-only",
+          "excludePrerelease": true
+        },
+        "diagnostics": {
+          "upgrade": true,
+          "deprecation": true,
+          "replacement": true,
+          "vulnerability": true,
+          "distTag": true,
+          "engineMismatch": true
+        },
+        "packageLinks": "declared"
+      }
+    }
+  }
+}
+```
+
+To override the launched language server command:
+
+```json
+{
+  "lsp": {
+    "npmx": {
+      "binary": {
+        "path": "node",
+        "arguments": [
+          "/absolute/path/to/vscode-npmx/packages/language-server/dist/index.cjs",
+          "--stdio"
+        ]
+      }
+    }
+  }
+}
+```
+
+## Notes
+
+- Zed dev extensions require Rust installed via `rustup`; the Zed docs explicitly call out that Homebrew Rust will not work for dev extension compilation.
+- This dev extension expects the repo-local language server bundle at `packages/language-server/dist/index.cjs`, so build the monorepo before installing it in Zed.
+- If you override `lsp.npmx.binary`, make sure the launched server process still receives an LSP transport argument such as `--stdio`.
