i wanna try this but i have no idea how to use Github. should i use a tutorial? should i ask a friend for help? i have no idea what to do
github is very good for version control(rolling back changes if you made an oopsie, basically push your stuff before making anything you would consider a "breaking change", it also let's you work fast and break things.), I would use github desktop if you are on windows(it simplifies the whole process with a gui). If you are on linux you could go for something like lazygit or just learn the git cli commands (the ones I recommend are push,pull,commit,add,init with these you can do most things until you get to like branch merging n stuff) this is a one person jam so I doubt you will need more than that
atlassian has some great getting started guides for git cli https://www.atlassian.com/git/tutorials/setting-up-a-repository
