+### Adding Wonder Splash Screens
+
+You can add wonder images to mods and they'll be displayed instead of the standard icon when a wonder is finished. The image needs to be a .png and 2:1 ratio so for example 200x100 px.
+
+Add the images to `/Images/WonderImages/`. They need to be named according to the name field in `Buildings.json`, so for example "Temple of Artemis.png" or "Stonehenge.png"
+
+Remember, to be compatible with mobile devices, a fresh atlas needs to be generated including these.
+
+### Adding Leader Portraits
+
+The base game comes without Leader Portraits, but is able to display them in greetings, Civilopedia, diplomacy screens, or the nation picker. A mod can supply these, by adding their images to `/Images/LeaderIcons/`. The file name must correspond exactly with the leader name of a nation as defined in Nations.json, or they will be ignored.
+
+These work best if they are square, between 100x100 and 256x256 pixels, and include some transparent border within that area.
+
+For example, [here](https://github.com/yairm210/Unciv-leader-portrait-mod-example) is mod showing how to add leader portraits, which can complement the base game.
