You can contribute to the guide and its texts with this tool. It allows to edit the text of several pages including the unit page, tips and tier list.
To get an account to access the edit page, contact me via discord. I only give access to people who are already known from discord or another platform. Once you get access you can then initialize the password and afterwards sign in to edit the texts.
There will be most likely options to contribute to the guide in the future in combination with a GitHub repository to edit the code and extend the guide.
