Like with most things, the best way forward is 20% reading (usually best done first) and 80% doing (usually best done when you feel you have no idea what you're doing 😂).

We have a couple of guides below, but there are plenty of others online like @DarthCoin and BTCSessions videos

Just go slowly and start with a small(ish) channel first, such as 1M sats. After you've read a bit and opened your first channel, read a bit more and also re-read over the new security issues as you'll "get" them better with the experience 👍
