+## Zed
+
+For the best Zed experience with Vite+, install the [oxc-zed](https://github.com/oxc-project/oxc-zed) extension from the Zed extensions marketplace. It provides formatting and linting via `vp check`.
+
+When you create or migrate a project, Vite+ prompts you to choose whether you want the editor config written for Zed.
+
+You can also manually set up the Zed config:
+
+`.zed/settings.json`
+
+```json
+{
+  "lsp": {
+    "oxlint": {
+      "initialization_options": {
+        "settings": {
+          "run": "onType",
+          "fixKind": "safe_fix",
+          "typeAware": true,
+          "unusedDisableDirectives": "deny"
+        }

+          "run": "onSave"
+        }
+      }
+    }
+  },
+  "languages": {
+    "JavaScript": {
+      "format_on_save": "on",
+      "prettier": { "allowed": false },
+      "formatter": [{ "language_server": { "name": "oxfmt" } }],
+      "code_action": "source.fixAll.oxc"
+    },
+    "TypeScript": {
+      "format_on_save": "on",
+      "prettier": { "allowed": false },
+      "formatter": [{ "language_server": { "name": "oxfmt" } }]

+      "prettier": { "allowed": false },
+      "formatter": [{ "language_server": { "name": "oxfmt" } }]
+    }
+  }
+}
+```
+
+Setting `oxfmt.configPath` to `./vite.config.ts` keeps editor format-on-save aligned with the `fmt` block in your Vite+ config. The full generated config covers additional languages (CSS, HTML, JSON, Markdown, etc.) — run `vp create` or `vp migrate` to get the complete file written automatically.
