+# my-patterns
+
+This directory can be used to save your own patterns, which then get
+made into a pattern swatch.
+
+Example: <https://felixroos.github.io/strudel/swatch/>
+
+## deploy
+
+### 1. fork the [strudel repo on github](https://github.com/tidalcycles/strudel.git)
+
+### 2. clone your fork to your machine `git clone https://github.com/<your-username>/strudel.git strudel && cd strudel`
+
+### 3. create a separate branch like `git branch patternuary && git checkout patternuary`
+
+### 4. save one or more .txt files in the my-patterns folder
+
+### 5. edit `website/public/CNAME` to contain `<your-username>.github.io/strudel`
+
+### 6. edit `website/astro.config.mjs` to use site: `https://<your-username>.github.io` and base `/strudel`, like this
+
+```js
+const site = 'https://<your-username>.github.io';
+const base = '/strudel';
+```
+
+### 7. commit & push the changes
+
+```sh
+git add . && git commit -m "site config" && git push --set-upstream origin
+```
+
+### 8. deploy to github pages
+
+- go to settings -> pages and select "Github Actions" as source
+- go to settings -> environments -> github-pages and press the edit button next to `main` and type in `patternuary` (under "Deployment branches")
+- go to Actions -> `Build and Deploy` and click `Run workflow` with branch `patternuary`
+
+### 9. view your patterns at `<your-username>.github.io/strudel/swatch/`
+
+Alternatively, github pages allows you to use a custom domain, like https://mycooldomain.org/swatch/. [See their documentation for details](https://docs.github.com/en/pages/configuring-a-custom-domain-for-your-github-pages-site).
+
+### 10. optional: automatic deployment
+
+If you want to automatically deploy your site on push, go to `deploy.yml` and change `workflow_dispatch` to `push`.
+
+## running locally
+
+- install dependencies with `npm run setup`
+- run dev server with `npm run repl` and open `http://localhost:3000/strudel/swatch/`
+
+## tests fail?
+
+Your tests might fail if the code does not follow prettiers format.
+In that case, run `npm run codeformat`. To disable that, remove `npm run format-check` from `test.yml`
+
+## updating your fork
+
+To update your fork, you can pull the main branch and merge it into your `patternuary` branch.

-## Development
-
-If you change something in here and want to see the changes in the repl, make sure to run `npm run build` inside this folder!
-
-```js
-npm run dev # dev server
-npm run build # build package
-```
+- Open [example on stackblitz](https://stackblitz.com/edit/react-ts-saaair?file=tune.tsx,App.tsx)
+- Also check out the [nano-repl](./examples/nano-repl/) for a more sophisticated example

+
+this is an example of how to create a repl with strudel and react.
+
+## Usage
+
+after cloning the strudel repo:
+
+```sh
+pnpm i
+cd packages/react/examples/nano-repl
+pnpm dev
+```
+
+you should now have a repl running at `http://localhost:5173/`
