All you need to do is to drag the orange “pill” found under “Updating Stroll” on https://giffmex.org/stroll/stroll.html onto a tiddlywiki instance, then click the “import” and “reload” buttons and you're all set.

I picked https://nesslabs.com/tiddlywiki-beginner-tutorial which uses https://noteself.org/. NoteSelf has autosync which is helpful.

I would recommend reading How To Take Smart Notes and really internalizing the information there, I started off way too fast and ended up with too many tiny notes. It takes practice but its definitely worth it.
