 To create a new program/library using Syndicate/js, use `yarn create @syndicate-lang DIRECTORY`:
 
-    yarn create @syndicate-lang myprogram
-    cd myprogram
-    yarn
-    node lib/index.js
+```shell
+yarn create @syndicate-lang myprogram
+cd myprogram
+yarn
+yarn serve
+```
+
+Then visit <http://localhost:8000/>. By default, the generated app expects a
+[syndicate-server](https://git.syndicate-lang.org/syndicate-lang/syndicate-rs/) to be running
+on port 9001 exposing a dummy capability to a dataspace entity. Suitable configuration can be
+found in the [`syndicate-server.config.pr`](template/syndicate-server.config.pr) file. Start
+the server like this:
+
+```shell
+syndicate-server -c ./syndicate-server.config.pr
+```
+
+If you aren't writing a web app in Syndicate, you can remove the following files from the
+generated module as well as the `serve` script from package.json:
+
+ - `index.html`
+ - `style.css`
+ - `rollup.config.js`
+ - `syndicate-server.config.pr`
+
+In that case, your `index.ts` can be as simple as
+
+```typescript
+import { Dataspace } from "@syndicate-lang/core";
+Dataspace.boot(ds => {
+    /* your app goes here */
+});
+```
+
+If you don't need to define any Preserves
+[schemas](https://preserves.gitlab.io/preserves/preserves-schema.html) in your application,
+remove the `protocols/` directory as well as the various `regenerate` scripts and any mention
+of the `src/gen/` directory from `package.json`.
