add-feature branch mentioned in documentation is missing

[schnitty]

From the documentation

We start with an Express application that represents a legacy project which we want to analyze. This Express application contains a "main" branch with the existing code. It also contains an "add-feature" branch that represents a new feature we want to develop for the application.

Go to Pull requests->New pull request and open a pull request from the add-feature branch to the main branch of your fork. Be careful that, by default, the PR targets the upstream repository.

There is no add-feature branch on the repository
