 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
-```
