 For the editing process, establish some practical rules on whether to use issues, branches and forks for adding content, fixing typos or making other changes. Furthermore, it can help to write down when you expect (draft) merge/pull requests and how to use the assign and review options in GitHub/GitLab. It is advisable to have at least a maintainer review each piece of content to maintain quality and consistency. Provide explanation on how you organize the book-editing and how you'd like to receive feedback in both the readme as the published book. The use of the [repository button {fa}`fa-github`, suggest edit {fa}`pencil` and issue button {fa}`lightbulb`](https://jupyterbook.org/en/stable/basics/repository.html) is advised.

 ## Define draft version of book
 If there's many people working on different parts of the book and material is staged for publication to students, we recommend using at least two separate branches, one which is released to students, the other one for development.  Using the [](../external/deploy-book-workflow/README.md), it's very easy to share multiple versions of your book on the same root-URL.

+As soon as you have different versions online, you have to make a decision about URLs. Using the [](../external/deploy-book-workflow/README.md), you can release the different version of your book all under the same root URL. So, it uses the same workflow as used for draft versions of your book as describe [before](draft_book), the only difference being that URLs of draft versions are generally not shared publicly.
 
 If you plan on maintaining only one public version, it is advisable to set `BEHAVIOR_PRIMARY` from the default `redirect` to `copy`. This ensures that the primary branch is copied to the root, making the URL more compact.
