Hero of Irdya I is a DLC for the turn-based strategy game, the Battle for Wesnoth. This is a single-player campaign that centres around Jahin, the greatest hero Irdya had ever known...
Released versions of Hero of Irdya I should be installed from Battle for Wesnoth’s official add-ons servers, via Battle for Wesnoth’s built-in add-ons manager, which can be accessed via the “Add-ons” button in the main menu.
Players who know how to use Github may clone my Git repository, which is to be found on my GitHub repository, into Battle for Wesnoth’s "userdata/data/add-ons/" directory The benefits of this is that you can try out the unreleased versions and let the author know of any bugs.
If you encounter any bugs or other problems, you may report them at my issue tracker on GitHub.
