Menril Basics
To get started with this mod, you will need to find some Menril Trees which can most easily be found in Meneglin Biomes.
After that, you’ll need to craft a Squeezer and Drying Basin for processing Menril Log. This can be done by placing a block of wood in the Squeezer and jumping on it until it's flat. Once that has been done, the Menril Resin will try to go to the two sides of the Squeezer. Next, place a Drying Basin next to the Squeezer to make it fill with the Menril Resin you just squeezed.
If you want to repeat the process, you can reset the Squeezer by applying a redstone pulse.
In the future, you will also be able to craft upgraded variants of these machines that are more easily automatable, but are more costly: the Mechanical Squeezer and the Mechanical Drying Basin.
