+- Being respectful of differing opinions, viewpoints, and experiences
+- Giving and gracefully accepting constructive feedback
+- Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+- Focusing on what is best not just for us as individuals, but for the overall
+  community
+
+Examples of unacceptable behavior include:
+
+- The use of sexualized language or imagery, and sexual attention or advances of
+  any kind
+- Trolling, insulting or derogatory comments, and personal or political attacks
+- Public or private harassment
+- Publishing others' private information, such as a physical or email address,

+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official email address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to [the community leaders responsible for enforcement](mailto:hello@gcmp.io).
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of
+actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or permanent
+ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the
+community.

-# Jazz - instant sync
+# Jazz - Build local-first apps
 
-<sub>Homepage: [jazz.tools](https://jazz.tools) &mdash; Docs: [DOCS.md](./DOCS.md) &mdash; Community & support: [Discord](https://discord.gg/utDMjHYg42) &mdash; Updates: [Twitter](https://twitter.com/jazz_tools) & [Email](https://gcmp.io/news)</sub>
+ **Jazz is an open-source toolkit for building apps with *distributed state.***
 
- **Jazz is an open-source toolkit for building apps with *secure sync.***
+## Getting started
 
-Quickly build and ship apps with:
+We recommend reading the [homepage](https://jazz.tools) and [docs](https://jazz.tools/docs) to get an overview of what Jazz is and how it works.
 
-- **Cross-device sync**
-- **Collaborative features** (incl. real-time multiplayer)
-- **Instantly reacting UIs**
-- Local-first storage & offline support
-- File upload and real-time media streaming
+If you're interested in contributing, please read [CONTRIBUTING.md](./CONTRIBUTING.md).
 
-# What is *secure sync*?
+For community and support, please join our [Discord](https://discord.gg/utDMjHYg42).
 
-**Sync** means that, *instead of making API requests*, you:
+---
 
-- **Read and write data as if it was local** &mdash; from anywhere in your app.
-- **Always have data synced to wherever it's needed, instantly:** to other devices of the same user, to other users, to your backend, to your local machine for debugging, etc.
+- Homepage: [jazz.tools](https://jazz.tools)
+- Docs: [jazz.tools/docs](https://jazz.tools/docs)
+- Community & support: [Discord](https://discord.gg/utDMjHYg42)
+- Updates: [Twitter](https://twitter.com/jazz_tools) & [Email](https://gcmp.io/news)
 
-**Secure** means that, *instead of relying on your API or DB for access control*, you:
-
-- **Set fine-grained, role-based permissions in `Group`s** that are **synced along with your data**.
-- **Permissions *verifiably enforced* everywhere,** using encryption & signatures under the hood.
-- **Change roles dynamically** for evolving teams, expiring invite links and more.
-
-# What's special about Jazz?
-
-Compared to other libraries and frameworks for local-first, sync-based or real-time apps, these are some of the things that make Jazz unique:
-
-- **Jazz is a *batteries-included,* vertically integrated toolkit,** offering everything you need to build an app, including auth, permissions, data model, sync, conflict resolution, blob storage, file uploads, real-time media streaming and more.
-- **Jazz has a *small API surface* of only a few abstractions to learn,** which combine in powerful ways to implement a broad set of features.
-- **Jazz *granularly* loads and caches *only the data that is needed*,** combining *local-first* instant UI reactivity and offline support with the on-demand data efficiency of conventional APIs
-- **Jazz supports end-to-end encryption, but doesn't require it,** allowing you to either manage your user's secret keys for them (based on existing auth flows) or letting your users
-- **Jazz is based on CoJSON, a soon-to-be *open standard,*** which means that there will be a whole ecosystem of compatible libraries and frameworks in a variety of environments &mdash; and it will be easy to achieve (secure) interop between Jazz/CoJSON-based apps and services.

-# Jazz Global Mesh
-
-Jazz is open source and you can run your own sync & storage server, but to really provide you with everything you need, we're also running
-**[Jazz Global Mesh](https://jazz.tools/mesh)**, a globally distributed mesh of servers optimized for:
-
- - **Ultra-low-latency sync** (with geo-aware edge caching and optimal routing)
- - **Low-cost, reliable storage**
-
-
-**Jazz Global Mesh is free for small volumes of data** and it's the **default syncing peer,** so you can  **start building multi-user Jazz apps with persistent data in minutes,** using only frontend code!
-
-# Getting started
-
-## Example App Walkthrough
-
-**For now the best tutorial is the walkthrough of the [Todo List Example App](#todo-list).**
-
-## General Scenarios
-
-### Building a new, entirely sync-based React app
-
-1. Define your data model with [cojson Collaborative Values (CoValues)](./DOCS.md#covalue).
-2. Implement permission logic using [cojson Groups](./DOCS.md#group).
-3. Build a user interface with [jazz-react](./DOCS.md#jazz-react) and [auto-sub](./DOCS.md#useautosubid).
-
-### Gradually adding sync to an existing React app
-
-Gradually migrate app features to use sync:
-
-1. Define data model for small aspect of your app with [cojson Collaborative Values (CoValues)](./DOCS.md#covalue).
-    - Schema adapters/importers for Prisma/Drizzle/PostgreSQL introspection coming soon.
-2. Map existing permission logic with [cojson Groups](./DOCS.md#group) & integrate existing auth.
-    - Auth integrations coming soon.
-3. Replace some of the React state and API requests in your UI with [jazz-react](./DOCS.md#jazz-react) and [auto-sub](./DOCS.md#useautosubid).
-
-# Example Apps
-
-## Todo List
-
-**A simple collaborative todo list app.**
-
-Live version: https://example-todo.jazz.tools
-
-Source code & walkthrough: [`./examples/todo`](./examples/todo)
-
-Demonstrates:
-  - Defining a data model with `CoMap`s and `CoList`s
-  - Creating data and setting permissions with `Group`s
-  - Fetching, rendering & editing data from nested `CoValue`s with reactive synced queries
-
-
-## Rate-My-Pet
-
-**A simple social polling app.**
-
-Live version: https://example-pets.jazz.tools
-
-Source code (walkthrough coming soon): [`./examples/pets`](./examples/pets)
-
-Demonstrates:
-  - Implementing per-account data streams (reactions) with `CoStream`s
-  - Implementing image upload and progressive image streaming using helpers from `jazz-react-media-images` (on top of CoJSON's `BinaryCoStreams` & `ImageDefinition` convention)
-
-
-# Documentation & API Reference
-
-For now, docs are hosted in a single well-structured markdown file: [`./DOCS.md`](./DOCS.md).
-
-- [Package Overview](./DOCS.md#overview)
-- [`jazz-react` API](./DOCS.md#jazz-react)
-- [`cojson` API](./DOCS.md#cojson)
-- [`jazz-browser-media-images` API](./DOCS.md#jazz-browser-media-images)
-
-
-In the future we'll build a dedicated docs page on the Jazz homepage.

+# Jazz Book Shelf Example
+
+Live version: [https://books-demo.jazz.tools](https://books-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`
+
+Install dependencies:
+
+```bash
+pnpm install
+```
+
+Go to the `examples/book-shelf` directory.
+
+```bash
+cd examples/book-shelf
+```
+
+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 Cloud](https://jazz.tools/cloud) (`wss://cloud.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/components/JazzAndAuth.tsx](./src/2_main.tsx).

+# Jazz Chat Example (with Clerk auth)
+
+Live version: [https://chat-clerk-demo.jazz.tools](https://chat-clerk-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/chat-clerk
+pnpm pack --pack-destination /tmp
+mkdir -p ~/jazz-examples/chat-clerk # or any other directory
+tar -xf /tmp/jazz-example-chat-* --strip-components 1 -C ~/jazz-examples/chat-clerk
+cd ~/jazz-examples/chat-clerk
+```
+
+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 Cloud](https://jazz.tools/cloud) (`wss://cloud.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).
