Any enthusiast Wesnoth add-on author is eligible for getting their own add-on or add-ons into the wesnoth-umc-dev repository. Although the project's original goal was to provide a mechanism for syncing the work of many authors on a single add-on, nowadays we are also hosting add-ons maintained by single individuals, or even dummy campaigns used as test cases for bugs in the mainline engine.
By add-on, it is understood that we may refer to Wesnoth campaigns, scenarios, eras, map packs, resource packages for other authors, etcetera.
The basic three steps for applying are:
We also welcome those add-ons to which step (3b) is not applicable, in other words, not-yet made add-ons. In this case, and in cases where an existing add-on is larger than 4.0 megabytes, we may ask you to check the files into the repository yourself.
