 ## Using Strudel In Your Project

-There are multiple npm packages you can use to use strudel, or only parts of it, in your project:
+This project is organized into many [packages](./packages), which are also available on [npm](https://www.npmjs.com/search?q=%40strudel).

- [`core`](./packages/core/): tidal pattern engine
- [`mini`](./packages/mini): mini notation parser + core binding
- [`transpiler`](./packages/transpiler): user code transpiler
- [`webaudio`](./packages/webaudio): webaudio output
- [`osc`](./packages/osc): bindings to communicate via OSC
- [`midi`](./packages/midi): webmidi bindings
- [`serial`](./packages/serial): webserial bindings
- [`tonal`](./packages/tonal): tonal functions
- ... [and there are more](./packages/)
-
-Click on the package names to find out more about each one.
+Read more about how to use these in your own project [here](https://strudel.cc/technical-manual/project-start).

-Note that the Code is placed inside HTML comments to prevent the browser from treating it as HTML.
+This will load the strudel website in an iframe, using the code provided within the HTML comments `<!-- -->`.
+The HTML comments are needed to make sure the browser won't interpret it as HTML.
+
+Alternatively you can create a REPL from JavaScript like this:
+
+```html
+<script src="https://unpkg.com/@strudel/embed@1.0.2"></script>
+<div id="strudel"></div>
+<script>
+  let editor = document.createElement('strudel-repl');

+.jux(rev)
+.room(2)
+.sometimes(add(note("12")))
+.lpf(perlin.range(200,20000).slow(4))`,
+  );
+  document.getElementById('strudel').append(editor);
+</script>
+```
+
+When you're using JSX, you could also use the `code` attribute in your markup:
+
+```html
+<script src="https://unpkg.com/@strudel/embed@1.0.2"></script>

 The Strudel REPL as a web component.

-[Usage example](https://github.com/tidalcycles/strudel/blob/main/examples/buildless/web-component-no-iframe.html)
+## Add Script Tag
+
+First place this script tag once in your HTML:
+
+```html
+<script src="https://unpkg.com/@strudel/repl@latest"></script>
+```
+
+You can also pin the version like this:
+
+```html
+<script src="https://unpkg.com/@strudel/repl@1.0.2"></script>
+```
+
+This has the advantage that your code will always work, regardless of potential breaking changes in the strudel codebase.
+See [releases](https://github.com/tidalcycles/strudel/releases) for the latest versions.
+
+## Use Web Component
+
+When you've added the script tag, you can use the `strudel-editor` web component:
+
+```html
+<strudel-editor>
+  <!--
+setcps(1)
+n("<0 1 2 3 4>*8").scale('G4 minor')
+.s("gm_lead_6_voice")
+.clip(sine.range(.2,.8).slow(8))
+.jux(rev)
+.room(2)
+.sometimes(add(note("12")))
+.lpf(perlin.range(200,20000).slow(4))
+-->
+</strudel-editor>
+```
+
+This will load the Strudel REPL using the code provided within the HTML comments `<!-- -->`.
+The HTML comments are needed to make sure the browser won't interpret it as HTML.
+
+Alternatively you can create a REPL from JavaScript like this:
+
+```html
+<script src="https://unpkg.com/@strudel/repl@latest"></script>
+<div id="strudel"></div>
+<script>
+  const repl = document.createElement('strudel-editor');
+  repl.setAttribute(
+    'code',
+    `setcps(1)
+n("<0 1 2 3 4>*8").scale('G4 minor')
+.s("gm_lead_6_voice")
+.clip(sine.range(.2,.8).slow(8))
+.jux(rev)
+.room(2)
+.sometimes(add(note("12")))
+.lpf(perlin.range(200,20000).slow(4))`,
+  );
+  document.getElementById('strudel').append(repl);
+</script>
+```
+
+## Interacting with the REPL
+
+If you get a hold of the `strudel-editor` element, you can interact with the strudel REPL from Javascript:
+
+```html
+<script src="https://unpkg.com/@strudel/repl@latest"></script>
+<strudel-editor id="repl">
+  <!-- ... -->
+</strudel-editor>
+<script>
+const repl = document.getElementById('repl');
+console.log(repl.editor);
+</script>
+```
+
+or
+
+```html
+<script src="https://unpkg.com/@strudel/repl@latest"></script>
+<div id="strudel"></div>
+<script>
+  const repl = document.createElement('strudel-editor');
+  repl.setAttribute('code', `...`);
+  document.getElementById('strudel').append(repl);
+  console.log(repl.editor);
+</script>
+```
+
+The `.editor` property on the `strudel-editor` web component gives you the instance of [StrudelMirror](https://github.com/tidalcycles/strudel/blob/a46bd9b36ea7d31c9f1d3fca484297c7da86893f/packages/codemirror/codemirror.mjs#L124) that runs the REPL.
+
+For example, you could use `setCode` to change the code from the outside, `start` / `stop` to toggle playback or `evaluate` to evaluate the code.
