 # Jazz - instant sync
 
-Homepage: [jazz.tools](https://jazz.tools) — [Discord](https://discord.gg/utDMjHYg42)
+<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 *secure telepathic data.*
+ **Jazz is an open-source toolkit for building apps with *secure sync.***
 
-- Ship faster & simplify your frontend and backend
-- Get cross-device sync, real-time collaboration & offline support for free
+Quickly build and ship apps with:
 
-[Jazz Global Mesh](https://jazz.tools/mesh) is serverless sync & storage for Jazz apps. (currently free!)
+- **Cross-device sync**
+- **Collaborative features** (incl. real-time multiplayer)
+- **Instantly reacting UIs**
+- Local-first storage & offline support
+- File upload and real-time media streaming
+
+# What is *secure sync*?
+
+**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.
+
+**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!
 
-## What is Secure Telepathic Data?
+# Getting started
 
-**Telepathic** means:
+## Example App Walkthrough
 
-- **Read and write data as if it was local,** from anywhere in your app.
-- **Always have that data synced, instantly.** Across devices of the same user &mdash; or to other users (coming soon: to your backend, workers, etc.)
+**For now the best tutorial is the walkthrough of the [Todo List Example App](#todo-list).**
 
-**Secure** means:
+## General Scenarios
 
-- **Fine-grained, role-based permissions are *baked into* your data.**
-- **Permissions are enforced everywhere, locally.** (using cryptography instead of through an API)
-- Roles can be changed dynamically, supporting changing teams, invite links and more.
+### Building a new, entirely sync-based React app
 
-## How to build an app with Jazz?
+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).
 
-### Building a new app, completely with Jazz
+### Gradually adding sync to an existing React app
 
-It's still a bit early, but these are the rough steps:
+Gradually migrate app features to use sync:
 
-1. Define your data model with [CoJSON Values](#cojson).
-2. Implement permission logic using [CoJSON Groups](#group).
-3. Hook up a user interface with [jazz-react](#jazz-react).
+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).
 
-The best example is currently the [Todo List app](#example-app-todo-list).
+# Example Apps
 
-### Gradually adding Jazz to an existing app
+## Todo List
 
-Coming soon: Jazz will support gradual adoption by integrating with your existing UI, auth and database.
+**A simple collaborative todo list app.**
 
-## Example App: Todo List
+Live version: https://example-todo.jazz.tools
 
-The best example of Jazz is currently the Todo List app.
+Source code & walkthrough: [`./examples/todo`](./examples/todo)
 
-- Live version: https://example-todo.jazz.tools
-- Source code: [`./examples/todo`](./examples/todo). See the README there for a walk-through and running instructions.
+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
 
-# Documentation
 
-Note: Since it's early days, this is the only source of documentation so far.
+## Rate-My-Pet
 
-If you want to build something with Jazz, [join the Jazz Discord](https://discord.gg/utDMjHYg42) for encouragement and help!
+**A simple social polling app.**
 
-## Overview: Main Packages
+Live version: https://example-pets.jazz.tools
 
-**`cojson`** → [DOCS](./DOCS.md#cojson)
+Source code (walkthrough coming soon): [`./examples/pets`](./examples/pets)
 
-A library implementing abstractions and protocols for "Collaborative JSON". This will soon be standardized and forms the basis of secure telepathic data.
+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)
 
-**`jazz-react`** → [DOCS](./DOCS.md#jazz-react)
 
-Provides you with everything you need to build react apps around CoJSON, including reactive hooks for telepathic data, local IndexedDB persistence, support for different auth providers and helpers for simple invite links for CoJSON groups.
+# Documentation & API Reference
 
-### Supporting packages
-<small>
+For now, docs are hosted in a single well-structured markdown file: [`./DOCS.md`](./DOCS.md).
 
-**`cojson-simple-sync`**
+- [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)
 
-A generic CoJSON sync server you can run locally if you don't want to use Jazz Global Mesh (the default sync backend, at `wss://sync.jazz.tools`)
 
-**`jazz-browser`**  → [DOCS](./DOCS.md#jazz-browser)
+In the future we'll build a dedicated docs page on the Jazz homepage.
 
-framework-agnostic primitives that allow you to use CoJSON in the browser. Used to implement `jazz-react`, will be used to implement bindings for other frameworks in the future.
+----
 
-**`jazz-react-auth-local`** (and `jazz-browser-auth-local`): A simple auth provider that stores cryptographic keys on user devices using WebAuthentication/Passkeys. Lets you build Jazz apps completely without a backend, with end-to-end encryption by default.
-
-**`jazz-storage-indexeddb`**
-
-Provides local, offline-capable persistence. Included and enabled in `jazz-react` by default.

+# Jazz Todo List Example
+
+Live version: https://example-todo.jazz.tools
+
+## Installing & running the example locally
+
+Start by checking out just the example app to a folder:
+
+```bash
+npx degit gardencmp/jazz/examples/todo jazz-example-todo
+cd jazz-example-todo
+```
+
+(This ensures that you have the example app without git history or our multi-package monorepo)
+
+Install dependencies:
+
+```bash
+npm install
+```
+
+Start the dev server:
+
+```bash
+npm run dev
+```
+
+## Structure
+
+- [`src/basicComponents`](./src/basicComponents): simple components to build the UI, unrelated to Jazz (uses [shadcn/ui](https://ui.shadcn.com))
+- [`src/components`](./src/components/): helper components that do contain Jazz-specific logic, but aren't very relevant to understand the basics of Jazz and CoJSON
+- [`src/1_types.ts`](./src/1_types.ts),
+[`src/2_main.tsx`](./src/2_main.tsx),
+[`src/3_NewProjectForm.tsx`](./src/3_NewProjectForm.tsx),
+[`src/4_ProjectTodoTable.tsx`](./src/4_ProjectTodoTable.tsx): the main files for this example, see the walkthrough below
+
+## Walkthrough
+
+### Main parts
+
+1. Defining the data model with CoJSON: [`src/1_types.ts`](./src/1_types.ts)
+
+2. The top-level provider `<WithJazz/>` and routing: [`src/2_main.tsx`](./src/2_main.tsx)
+
+3. Creating a new todo project: [`src/3_NewProjectForm.tsx`](./src/3_NewProjectForm.tsx)
+
+4. Reactively rendering a todo project as a table, adding and editing tasks: [`src/4_ProjectTodoTable.tsx`](./src/4_ProjectTodoTable.tsx)
+
+### Helpers
+
+- (not yet explained) Creating invite links/QR codes with `<InviteButton/>`: [`src/components/InviteButton.tsx`](./src/components/InviteButton.tsx)
+
+This is the whole Todo List app!
+
+## 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/?sync=ws://localhost:4200`), or by setting the `sync` parameter of the `<WithJazz>` provider component in [./src/2_main.tsx](./src/2_main.tsx).

+# Jazz Todo List Example
+
+Live version: https://example-todo.jazz.tools
+
+## Installing & running the example locally
+
+Start by checking out just the example app to a folder:
+
+```bash
+npx degit gardencmp/jazz/examples/todo jazz-example-todo
+cd jazz-example-todo
+```
+
+(This ensures that you have the example app without git history or our multi-package monorepo)
+
+Install dependencies:
+
+```bash
+npm install
+```
+
+Start the dev server:
+
+```bash
+npm run dev
+```
+
+## Structure
+
+- [`src/basicComponents`](./src/basicComponents): simple components to build the UI, unrelated to Jazz (uses [shadcn/ui](https://ui.shadcn.com))
+- [`src/components`](./src/components/): helper components that do contain Jazz-specific logic, but aren't very relevant to understand the basics of Jazz and CoJSON
+- [`src/1_types.ts`](./src/1_types.ts),
+[`src/2_main.tsx`](./src/2_main.tsx),
+[`src/3_NewProjectForm.tsx`](./src/3_NewProjectForm.tsx),
+[`src/4_ProjectTodoTable.tsx`](./src/4_ProjectTodoTable.tsx): the main files for this example, see the walkthrough below
+
+## Walkthrough
+
+### Main parts
+
+1. Defining the data model with CoJSON: [`src/1_types.ts`](./src/1_types.ts)
+
+2. The top-level provider `<WithJazz/>` and routing: [`src/2_main.tsx`](./src/2_main.tsx)
+
+3. Creating a new todo project: [`src/3_NewProjectForm.tsx`](./src/3_NewProjectForm.tsx)
+
+4. Reactively rendering a todo project as a table, adding and editing tasks: [`src/4_ProjectTodoTable.tsx`](./src/4_ProjectTodoTable.tsx)
+
+### Helpers
+
+- (not yet explained) Creating invite links/QR codes with `<InviteButton/>`: [`src/components/InviteButton.tsx`](./src/components/InviteButton.tsx)
+
+This is the whole Todo List app!
+
+## 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/?sync=ws://localhost:4200`), or by setting the `sync` parameter of the `<WithJazz>` provider component in [./src/2_main.tsx](./src/2_main.tsx).

+# Jazz Todo List Example
+
+Live version: https://example-todo.jazz.tools
+
+## Installing & running the example locally
+
+Start by checking out just the example app to a folder:
+
+```bash
+npx degit gardencmp/jazz/examples/todo jazz-example-todo
+cd jazz-example-todo
+```
+
+(This ensures that you have the example app without git history or our multi-package monorepo)
+
+Install dependencies:
+
+```bash
+npm install
+```
+
+Start the dev server:
+
+```bash
+npm run dev
+```
+
+## Structure
+
+- [`src/basicComponents`](./src/basicComponents): simple components to build the UI, unrelated to Jazz (uses [shadcn/ui](https://ui.shadcn.com))
+- [`src/components`](./src/components/): helper components that do contain Jazz-specific logic, but aren't very relevant to understand the basics of Jazz and CoJSON
+- [`src/1_types.ts`](./src/1_types.ts),
+[`src/2_main.tsx`](./src/2_main.tsx),
+[`src/3_NewProjectForm.tsx`](./src/3_NewProjectForm.tsx),
+[`src/4_ProjectTodoTable.tsx`](./src/4_ProjectTodoTable.tsx): the main files for this example, see the walkthrough below
+
+## Walkthrough
+
+### Main parts
+
+1. Defining the data model with CoJSON: [`src/1_types.ts`](./src/1_types.ts)
+
+2. The top-level provider `<WithJazz/>` and routing: [`src/2_main.tsx`](./src/2_main.tsx)
+
+3. Creating a new todo project: [`src/3_NewProjectForm.tsx`](./src/3_NewProjectForm.tsx)
+
+4. Reactively rendering a todo project as a table, adding and editing tasks: [`src/4_ProjectTodoTable.tsx`](./src/4_ProjectTodoTable.tsx)
+
+### Helpers
+
+- (not yet explained) Creating invite links/QR codes with `<InviteButton/>`: [`src/components/InviteButton.tsx`](./src/components/InviteButton.tsx)
+
+This is the whole Todo List app!
+
+## 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/?sync=ws://localhost:4200`), or by setting the `sync` parameter of the `<WithJazz>` provider component in [./src/2_main.tsx](./src/2_main.tsx).
