[adverbly]

I keep a git repository with mostly markdown files. Its secure, searchable, free, updatable and retrievable anywhere. I can edit it easily with my favorite text editor of the day. I can also include other file types.

Knowledge itself I keep written in markdown files. I keep folders, multiple files, and headings within files to organize and group things by topic. Everything is in unordered bullet points. The bullet points can be nested as well.

Indentation from nested bullets, plus the syntax highlighting for headers gives visual indication of where related material is located.
