Simply put the name of the application in the list. Link to its homepage or a guide on how to install it. Also write a short description for the application + add icon. Make sure it is put under the appropriate topic. If the application doesn't fit in any existing topic, make a new one for it. Ensure everything is alphabetically sorted.

Unsure how to contribute?

Author's note: Recently, I received feedbacks from you about the quality of some applications on this list. I myself tested them out a lot (not all of them, though). If you have any problems with the apps, please: -> head to the dev page (if available) -> make an issue for the dev there -> make an issue here so that I can consider whether I should get the app out of the list. Remember : Everything has its own quality, so there will never be anything like "best app" or "selective list" here, thank you.
