 ## Setup
 
-There are packages used from github so we need to follow the following steps to install them:
-
-1. Create a github PAT (personal access token) if it does not already exist.
-
-   https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token#creating-a-token
-
-2. Configure the PAT with scopes mentioned in https://docs.github.com/en/packages/learn-github-packages/about-permissions-for-github-packages#about-scopes-and-permissions-for-package-registries. This is required to install or publish github packages.
-
-3. Follow the steps in https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-npm-registry#authenticating-with-a-personal-access-token to authenticate to github packages. We can also run the follwing to authenticate by logging in to npm.
-
-   ```bash
-   $ npm login --scope=@cerc-io --registry=https://npm.pkg.github.com
-
-   > Username: USERNAME
-   > Password: TOKEN
-   > Email: PUBLIC-EMAIL-ADDRESS
-   ```
-
-   Replace with the following:
-   - `USERNAME`: GitHub username
-   - `TOKEN`: Personal access token (configured above)
-   - `PUBLIC-EMAIL-ADDRESS`: Email address
-
-4. When authenticating to github packages for the first time, yarn install may throw Unauthorized error. To overcome this we need to run yarn install in `packages/graph-node` directory. After this yarn install for watcher-ts works properly even from root of the repo.

 This project uses [yarn workspaces](https://classic.yarnpkg.com/en/docs/workspaces/).
