+## Cozy-Devtools
+
+Cozy-Devtools exposes a devtool that can be injected in an app for debug
+and better developer experience. It is inspired by the [awesome devtools
+for react-query][react-query devtools].
+
+To activate it, just run in your browser console:
+
+```js
+flag('debug', true)
+```
+
+### Usage
+
+Before using the devtools, you need to install cozy-ui and react-inspector.
+
+```bash
+yarn add cozy-ui # >= 48.0.0
+yarn add react-inspector # >= 5.1.0
+```
+
+Next, you need to add it to your app, inside a CozyProvider.
+
+```jsx
+import CozyClient, { CozyProvider } from 'cozy-client'
+import CozyDevtools from 'cozy-client/dist/devtools'
+
+const App = () => {
+  return <CozyProvider client={client}>
+     /* Your app is here */
+     { process.env.NODE_ENV !== 'production' ? <CozyDevtools /> : null }
+  </CozyProvider>
+}
+```
+
+### Panels
+
+- The devtools is made of several "panels".
+- There are default panels and the app can also inject its own adhoc panels.
+
+#### Queries
+
+Shows current queries inside cozy-client cache. Allows to see the data of
+the query. The execution time is also shown, and is very valuable to track
+down performance issues. It uses the execution statistics collected
+from CouchDB.
+
+#### Flags
+
+Shows all the current flags and allow to modify them.
+
+#### Libraries
+
+Show library versions based on the global **VERSIONS** variable that
+should be injected by the app. If it is defined, the panel will be blank.
+
+#### PouchLink
+
+If you use the PouchLink to synchronize your data to PouchDB, you can use
+the optional devtool PouchLink devtool panel. Since PouchDB is optional,
+it is not available by default and you need to explicitly tell the Devtools
+to display it.
+
+```jsx
+import PouchDevtools from 'cozy-client/dist/devtools/Pouch'
+
+() => <CozyDevTools panels={{ id: 'pouch', Component: PouchDevtools}} />
+```
+
+### Ideas for next features
+
+- Performance tips in query panels
+
+  - Show index related tips
+  - Show slow queries
+  - Show repeating queries
+  - Show queries downloading too much data
+
+- Actions on queries
+
+  - Reset data inside query
+  - Refetch
+  - Set to error
+  - Delete from store
+
+If you have any other idea, please [open an issue][open-issue] 👍
