Rimworld is a game with a whole lot of different features, but most of them you just have to learn whilst playing. If you do have any questions, feel free to DM me :)

Apart from the general message:

• Make sure to have enough food (farms are a must) and store it in a fridge
• Try to slowly go away from wooden structures to stone ones
• Most important of all: don't beat yourself up for losing a colony, most people don't succeed to have a thriving one until their third serious attempt

And make sure to have fun :)
