+## Lignumis
+
 This mod extends the early game of Space Age by putting you on the moon "Lignumis" before you escape to Nauvis. It concentrates on wood and steam technologies, giving you some early game production chains for those resources.
 
 The duration of the stay on Lignumis will be rather short. The impact of the later game will still be substantial (once implemented).
 
 **Warning when adding to existing games:** With the default settings, this mod will break a few things in your existing bases and space ships. Check out the settings to disable what you don't like.

 ## Problematic / incompatible mods
 
 * The combination of AAI Industry and Any planet start is currently not supported.
 * Alien Biomes: Lignumis won't have any trees. It's playable, but not as intended.
 * The rest of the Wooden Universe: I marked the ones incompatible that don't make sense to combine or that wouldn't add more that is not already included.
