Find IL's that are simple and that you find fun. Learn their route, look at current runs to see how others do it. Eventually, move into full game stuff when you get comfortable.

Hi and welcome, the best way to start doom is play what you enjoy the most like an IL in the Level Leaderboards section or Full game Leaderboard, find a way to record the best quality gameplay and do what you wish to run. For example, if you enjoy playing Episode 1 full game the most, do that. All I can say is run the categories you enjoy the most to get the best start of enjoying to speedrun doom.
