 The entry point for the wiki is the [Home page](Home.md).
 
 A while ago, Travis CI executed such bash script each time the `master` branch changed.
 This is not working for the moment, but contributors can execute the following command in a terminal:
 
 ```bash

 where `<<TOKEN>>` is a [GitHub Personal Token](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token) with repo:write permissions on this repository.
