            ### 📦 PR Packages

            Install this PR (you need to setup Github packages):

            ```bash
            yarn add @superfluid-finance/ethereum-contracts@PR${{ steps.pr.outputs.pr_number }}
            yarn add @superfluid-finance/sdk-core@PR${{ steps.pr.outputs.pr_number }}
            yarn add @superfluid-finance/sdk-redux@PR${{ steps.pr.outputs.pr_number }}
            ```

            <details><summary>:octocat: Click to learn how to use Github packages</summary>

            To use the Github package registry, create a token with "read:packages" permission. See [Creating a personal access token](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token) for help.

            Next add these lines to your `.npmrc` file, replacing TOKEN with your personal access token. See [Installing a package from Github](https://docs.github.com/en/packages/guides/configuring-npm-for-use-with-github-packages#installing-a-package) if you get stuck.

            ```
            @superfluid-finance:registry=https://npm.pkg.github.com
            //npm.pkg.github.com/:_authToken=TOKEN
            ```
