 ## Installation
 
+Plugins are compatible with both [GitHub Copilot CLI] and [Claude Code].

 ```bash
 copilot plugin marketplace add heaths/plugins
 ```

+
+## Sharing with contributors
+
+You can recommend this marketplace and its plugins to everyone who works in a repository by committing a `.claude/settings.json` file to that repository. When contributors trust the project folder in [Claude Code], they are prompted to install the marketplace and any enabled plugins.
+
+Example `.claude/settings.json`:
+
+```json
+{
+  "extraKnownMarketplaces": {
+    "heaths-plugins": {
+      "source": {
+        "source": "github",
+        "repo": "heaths/plugins"
+      }
+    }
+  },
+  "enabledPlugins": {
+    "linting@heaths-plugins": true
+  }
+}
+```
+
+> **Note:** [GitHub Copilot CLI] does not currently support project-level plugin recommendations. Contributors using Copilot CLI should run the marketplace and plugin install commands above individually.
