 There are still many tests that have not been written yet! Reading and writing tests is a great opportunity to get familiar with the codebase.
-You can find the tests in each package in the `test` folder. To run all tests, run `pnpm test` from the root folder.
+You can find the tests in each package in the `test` folder. To run all tests, run `npm test` from the root folder.
 
 ## Project Setup
 
 To get the project up and running for development, make sure you have installed:
 
-- [git](https://git-scm.com/)
-- [node](https://nodejs.org/en/) >= 18
-- [pnpm](https://pnpm.io/) (`npm i pnpm -g`)
+- git
+- node, preferably v16

 git clone https://github.com/tidalcycles/strudel.git && cd strudel

-pnpm start # start repl
+npm i # install at root to symlink packages
+npx lerna bootstrap # install all dependencies in packages

-## ESLint
-
-To prevent unwanted runtime errors, this project uses [eslint](https://eslint.org/).
-
-- You can check for lint errors by running `pnpm lint`
-
-There are also eslint extensions / plugins for most editors.
-
-## Running Tests
-
-- Run all tests with `pnpm test`
-- Run all tests with UI using `pnpm test-ui`
-
-## Running all CI Checks
-
-When opening a PR, the CI runner will automatically check the code style and eslint, as well as run all tests.
-You can run the same check with `pnpm check`
-
 ## Package Workflow
 
 The project is split into multiple [packages](https://github.com/tidalcycles/strudel/tree/main/packages) with independent versioning.
-When you run `pnpm i` on the root folder, [pnpm workspaces](https://pnpm.io/workspaces) will install all dependencies of all subpackages. This will allow any js file to import `@strudel.cycles/<package-name>` to get the local version,
-allowing to develop multiple packages at the same time.
+When you run `npm i` on the root folder, [npm workspaces](https://docs.npmjs.com/cli/v7/using-npm/workspaces) will symlink all packages
+in the `node_modules` folder. This will allow any js file to import `@strudel.cycles/<package-name>` to get the local version,
+which allows developing multiple packages at the same time
 
 ## Package Publishing
 
@@ -123,25 +103,15 @@ To publish all packages that have been changed since the last release, run:
 
 ```sh
 npm login
-
-# this will increment all the versions in package.json files of non private packages to selected versions
-npx lerna version --no-private
-
-# publish all packages inside /packages using pnpm! don't use lerna to publish!!
-pnpm --filter "./packages/**" publish --dry-run
-
-# the last command was only a dry-run, make sure everything looks ok, if yes, run the same command without flag
+npx lerna publish
 ```
 
-To manually publish a single package, increase the version in the `package.json`, then run `pnpm publish`.
-Important: Always publish with `pnpm`, as `npm` does not support overriding main files in `publishConfig`, which is done in all the packages.
-
 ### New Packages
 
 To add a new package, you have to publish it manually the first time, using:
 
 ```sh
-cd packages/<package-name> && pnpm publish --access public
+cd packages/<package-name> && npm publish --access public
 ```

 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/>
+0. fork and clone the strudel repository
+1. run `npm run setup` in the strudel folder
+1. Save one or more .txt files in this folder
+2. run `npm run repl` in the top-level strudel folder
+3. open `http://localhost:3000/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/`
+1. in your fork, go to settings -> pages and select "Github Actions" as source
+2. edit `website/public/CNAME` to contain `<your-username>.github.io/strudel`
+3. edit `website/astro.config.mjs` to use site: `https://<your-username>.github.io` and base `/strudel`
+4. go to Actions -> `Build and Deploy` and click `Run workflow`
+5. 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.
