Welcome to the forum and nice first guide, @TaigaBiome ! Check out the #beginner-must-read and forum-tips for more easy help! Read the Community Guidelines for a gist of the rules. If you ever run into a hard problem, talk to anyone who has the word “Regular” next to their profile name. They can help you with hard and in-depth concepts and mechanics!
You may want to credit this guide, though. It was made first.
