 ### Setup
 
-To build the project, a recent version of [Node.js](https://nodejs.org/en/) is required in addition to the [Yarn](https://yarnpkg.com/) package manager. Once installed, login to the `@siteimprove` scope, if you aren't already, to ensure that all dependencies can be fetched:
+To build the project, a recent version of [Node.js](https://nodejs.org/en/) is required in addition to the [Yarn](https://yarnpkg.com/) package manager. Once installed, do:
 
-```sh
-yarn npm login --scope siteimprove
-```
-
-> :warning: This command must be run from the root of the repository as the registry address of the `@siteimprove` scope is defined in the [local Yarn configuration](.yarnrc.yml).
-
-You will be prompted for your GitHub username and a personal access token. If you don't already have an access token, [generate a new one](https://github.com/settings/tokens/new "Generate a personal access token") with the `read:packages` permission and paste it into the prompt.

->- **If that does not work** run
->  ```
->  yarn config set --home "npmRegistries['https://npm.pkg.github.com'].npmAuthToken" <your-token>
->  ```
->  It will create a file `.yarnrc.yml` on your machine. This is a private file for your user, only. It will most likely be saved in a path like `C:\Users\<username>\.yarnrc.yml`
->
-> - **If that fails** and the file content is different than the below code then you can manually update the file. MAKE SURE to edit your own `.yarnrc.yml` file, not the one in this repository. The reason is because your `npmAuthTokens` should never be committed to a shared repository - keep it secret on your local machine.
