+description: Add Agentation visual feedback toolbar to a Next.js project
+---
+
+# Agentation Setup
+
+Set up the Agentation annotation toolbar in this project.
+
+## Steps
+
+1. **Check if already installed**
+   - Look for `agentation` in package.json dependencies
+   - If not found, run `npm install agentation` (or pnpm/yarn based on lockfile)
+
+2. **Check if already configured**
+   - Search for `<Agentation` or `import { Agentation }` in src/ or app/
+   - If found, report that Agentation is already set up and exit
+
+3. **Detect framework**
+   - Next.js App Router: has `app/layout.tsx` or `app/layout.js`
+   - Next.js Pages Router: has `pages/_app.tsx` or `pages/_app.js`
+
+4. **Add the component**
+
+   For Next.js App Router, add to the root layout:
+   ```tsx
+   import { Agentation } from "agentation";
+
+   // Add inside the body, after children:
+   {process.env.NODE_ENV === "development" && <Agentation />}
+   ```
+
+   For Next.js Pages Router, add to _app:
+   ```tsx
+   import { Agentation } from "agentation";
+
+   // Add after Component:
+   {process.env.NODE_ENV === "development" && <Agentation />}
+   ```
+
+5. **Confirm setup**
+   - Tell the user to run their dev server and look for the Agentation toolbar (floating button in bottom-right corner)
+
+## Notes
+
+- The `NODE_ENV` check ensures Agentation only loads in development
+- Agentation requires React 18
+- No additional configuration needed — it works out of the box
