-This is an early version of the mod. It contains all the content that was originally planned but still needs some balancing and polishing.

+## Add compatibility to your mod
+
+Lignumis, by default, adds wood and steam science packs during `data-updates.lua` to all technologies that match certain
+criteria.
+First it looks at a whitelist of science packs. If a technology has any of those, it is considered a candidate for
+adding the science packs.
+Then a blacklist for science packs and specific technology names is applied.
+
+Also, Lignumis adds wood and steam science packs during `data-updates.lua` to all labs' inputs. If your lab is special
+use the `lab_blacklist` described below.
+
+These lists are made available in `data.lua` in a global table called `Lignumis` to add compatibility for other mods.
+
+#### `science_pack_whitelist`
+
+A technology having any of these science packs as ingredient will get wood and steam science packs added.
+
+As wood science packs can't be imported before coming back to Lignumis, only advanced Nauvis science packs are added
+here and exceptions are needed for advanced technologies that are required to upgrade Lignumis to export science packs.
+
+#### `science_pack_blacklist`
+
+A technology is skipped if it has any of these as ingredient.
+
+If you have a planet that only uses its own science packs and must not rely on other science packs to be imported, add
+your science packs to the blacklist.
+
+#### `science_blacklist`
+
+These technologies are skipped even if they are matches according to above lists.
+
+Use this list if you want to have wood and steam science packs added to most of your technologies, but skip some.
+Lignumis uses this list for technologies that match the whitelist but are required for coming back to Lignumis in order
+to create the science pack export.
+
+#### `lab_blacklist`
+
+Don't touch inputs for labs in this list.
+
+Lignumis adds wood and steam science packs to all labs' inputs in `data-updates.lua` so modded labs will support them.
+If your modded lab is special and it should not support these science packs, use this list or set the inputs in `data-final-fixes.lua`.
