You can use the Wiki Pages feature to create content on a variety of topics related to your project. Wiki pages can be created and updated by any project member.
Of course, you can use it in other ways too, based on your project requirements.
There is a possibility that two project members may be working on a Wiki page at the same time. In such instances, when you try to publish your page, you might get the following message:
"Sorry. This wiki page has been modified by somebody else since you started editing. Your changes can't be saved."
Best Practice: While we’re working on providing you with a better experience, as a best practice, you may want to manage Wiki pages by having a designated project member to update Wiki pages in addition to publishing content often.
