+# 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).
