+# Jazz Chat Example
+
+Live version: [https://chat.jazz.tools](https://chat.jazz.tools)
+
+## Installing & running the example locally
+
+(this requires `pnpm` to be installed, see [https://pnpm.io/installation](https://pnpm.io/installation))
+
+Start by checking out `jazz`
+
+```bash
+git clone https://github.com/gardencmp/jazz.git
+cd jazz/examples/chat
+pnpm pack --pack-destination /tmp
+mkdir -p ~/jazz-examples/chat # or any other directory
+tar -xf /tmp/jazz-example-chat-* --strip-components 1 -C ~/jazz-examples/chat
+cd ~/jazz-examples/chat
+```
+
+This ensures that you have the example app without git history and independent of the Jazz multi-package monorepo.
+
+Install dependencies:
+
+```bash
+pnpm install
+```
+
+Start the dev server:
+
+```bash
+pnpm dev
+```
+
+## Questions / problems / feedback
+
+If you have feedback, let us know on [Discord](https://discord.gg/utDMjHYg42) or open an issue or PR to fix something that seems wrong.
+
+## 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 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).

+# Jazz Music Player Example
+
+Live version: https://music-demo.jazz.tools
+
+## Installing & running the example locally
+
+(this requires `pnpm` to be installed, see [https://pnpm.io/installation](https://pnpm.io/installation))
+
+Start by checking out `jazz`
+
+```bash
+git clone https://github.com/gardencmp/jazz.git
+cd jazz/examples/musicPlayer
+pnpm pack --pack-destination /tmp
+mkdir -p ~/jazz-examples/musicPlayer # or any other directory
+tar -xf /tmp/jazz-example-musicPlayer-* --strip-components 1 -C ~/jazz-examples/musicPlayer
+cd ~/jazz-examples/musicPlayer
+```
+
+This ensures that you have the example app without git history and independent of the Jazz multi-package monorepo.
+
+Install dependencies:
+
+```bash
+pnpm install
+```
+
+Start the dev server:
+
+```bash
+pnpm dev
+```
+
+## Questions / problems / feedback
+
+If you have feedback, let us know on [Discord](https://discord.gg/utDMjHYg42) or open an issue or PR to fix something that seems wrong.
+
+## 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/?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).
