Users who have tried adding a repo to the NHS Digital org have faced these problems (which we could mention in the guidance):

• Navigating to your prototype in the terminal

Users who have tried adding a repo to the NHS Digital org have faced these problems (which we could mention in the guidance):

* [Navigating to your prototype in the terminal](https://prototype-kit.service-manual.nhs.uk/install/mac/open)

* [Creating a personal access token (classic)](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens#creating-a-personal-access-token-classic)

Could this be worked in through a third paragraph under the 'Storing your code in GitHub' H2? E.g.
