 ## Using Strudel In Your Project

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

-Read more about how to use these in your own project [here](https://strudel.cc/technical-manual/project-start).
+- [`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/)

-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

-<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>
-<strudel-repl code={`

 The Strudel REPL as a web component.

-## 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.
