Post History

I almost never use computerized tools for gaming, instead favouring a variety of note-taking that is nowadays called "bullet journalling" (though the technique long predates the popularization of that term).  A brief summary (you'll have to dig up "bullet journal" on a search for full details) follows.

Equipment: notebook (make it cheap and nasty if you like, or horrendously expensive and fancy—whichever suits your fancy!), and writing implement(s).  Optionally a collection of [unobtrusive paperclips](https://rpg.codidact.com/uploads/nw7yntdpc6u6whmflnyju59qruee) or things like so-called ["book darts"](https://rpg.codidact.com/uploads/1dccvytj6s8957o5wdeia67jugjc) can be useful.

1. Open your notebook to the first page.  Number that page "1" if you're using an unnumbered notebook.  On that page write "Contents" at the top and put down a bullet point.
2. Turn to page 2.  Number it if necessary.  Write down a title for the contents on that page.  Put that title next to the bullet point on page 1, along with a page number.  Add a new bullet point.  Start filling in your content.  (Keep numbering your pages as you write if you're using a plain notebook.)
3. As you find new things to write about, put the title next to the current bullet point, along with the page number, until you fill the content page.  The last content bullet point should be some form of "continued on..." marker with a page number where you start a *new* content page.  (If you use book darts, or some such, I'd recommend marking your "Contents" pages for rapid access.  If you have colour-coded markers, the additional ability to identify things by type of content is helpful, but can start getting distracting.)

What you have in the end is what amounts to a linked list of content pages (which you can rapidly flip through if marked conveniently) to locate your content each referencing detailed information that you provide for your game.  Because you tend to document things at need, related information tends to be grouped together under the same Contents pages making localized access quicker as well, while keeping "distant" information still in accessible and readily locatable space.

There's as many approaches to bullet journaling as there are people who use it, so be sure to look around.  You can even get books specifically made for it (though I personally find that a bit weird).
