+      <Steps>
+        <Step>
+          Start a Claude Code instance:
+
+          ```bash
+          claude
+          ```
+        </Step>
+        <Step>
+          Add the Semgrep marketplace:
+
+          ```bash
+          /plugin marketplace add semgrep/guardian-claude
+          ```
+        </Step>
+        <Step>
+          Install the plugin from the marketplace:
+
+          ```bash
+          /plugin install semgrep-plugin@semgrep-guardian-claude
+          ```
+        </Step>
+        <Step>
+          Tell Claude to load the plugin:
+
+          ```bash
+          /reload-plugins
+          ```
+        </Step>
+        <Step>
+          Start a new session in Claude to begin the Semgrep login flow:
+
+          ```bash
+          /clear
+          ```
+
+          Alternatively, exit and relaunch Claude Code.
