 ## Configuration: sync server
 
 By default, the example app uses [Jazz Global Mesh](https://jazz.tools/mesh) (`wss://sync.jazz.tools`) - so cross-device use, invites and collaboration should just work.
 
-You can also run a local sync server by running `npx cojson-simple-sync`
+You can also run a local sync server by running `npx jazz-run sync` and adding the query param `?sync=ws://localhost:4200` to the URL of the example app (for example: `http://localhost:5173/?peer=ws://localhost:4200`), or by setting the `sync` parameter of the `<Jazz.Provider>` provider component in [./src/components/JazzAndAuth.tsx](./src/2_main.tsx).

 ## Configuration: sync server
 
 By default, the example app uses [Jazz Global Mesh](https://jazz.tools/mesh) (`wss://sync.jazz.tools`) - so cross-device use, invites and collaboration should just work.
 
-You can also run a local sync server by running `npx cojson-simple-sync` and adding the query param `?sync=ws://localhost:4200` to the URL of the example app (for example: `http://localhost:5173/?sync=ws://localhost:4200`), or by setting the `sync` parameter of the `<WithJazz>` provider component in [./src/2_main.tsx](./src/2_main.tsx).
+You can also run a local sync server by running `npx jazz-run sync` and adding the query param `?sync=ws://localhost:4200` to the URL of the example app (for example: `http://localhost:5173/?peer=ws://localhost:4200`), or by setting the `sync` parameter of the `<Jazz.Provider>` provider component in [./src/2_main.tsx](./src/2_main.tsx).
