 ### Configuration
 
 Solargraph reads its configuration from a file called `.solargraph.yml` in the root of your project. For more information about this file, see the [Solargraph configuration documentation](https://solargraph.org/guides/configuration).

+### Setting up `ruby-lsp`
+
+Zed currently doesn't install Ruby LSP automatically. To use Ruby LSP, you need to install the gem. Zed just looks for an executable called `ruby-lsp` on your `PATH`.
+
+You can install the gem manually with the following command:
+
+```shell
+gem install ruby-lsp
+```
+
+Ruby LSP uses pull-based diagnostics which Zed doesn't support yet. We can tell Zed to disable it by adding the following to your `settings.json`:
+
+```json
+{
+  "lsp": {
+    "ruby-lsp": {
+      "initialization_options": {
+        "enabledFeatures": {
+          "diagnostics": false
+        }
+      }
+    }
+  }
+}
+```
