If the elisp intro doesn’t suit your prefered style of learning two alternatives are to search the index in the emacs or elisp reference manual you access by
f1 r
f1 R elisp
then you followup in the case of elisp with “I excursion” to list the index topic on that keyword excursion as an example; better to look for blogs on the web as a first step to find the solution to your immediate need
Outside of the org box you can use gemini-mode, Gemini Protocol an evolution in between gopher and the web, and the elpher Gemini browser.
Have a look at the GNU Texinfo manual
https://www.gnu.org/software/texinfo/manual/texinfo/
at the moment I use GNU Emacs and Plan 9 User Space with that, oh, and Git.
There’s an article on osnews saying content farms are writing for search engine optimization leading to bots training bots and the human touch in writing is becoming unsustainable financially. I was concerned recommending a search on the words “texinfo manual” might not get you to the source text.
To the OP, use M-x customize-group RET backup
There you’ll find options for keeping number of backups and where they store.
git is the tool to rely on for version tracking at any granularity you decide, keep committing and logging your changes and you can go back to any point with the builtin vc tool, for example, C-x v l, for logs, C-x v =, for changes, C-x v v, for next step, see the manual f1-r
Should I worry that the utf-8 file I start editing becomes a text-raw-unix file on save and git commit over tramp/scp as indicated by the initial character on the modeline changing from U to t?
The messages buffer mentions tramp encoding/decoding using

Like evolution repeatedly finding the crab’s body plan an optimal design solution for doing the locomotion on the bottom of oceans, will AI evolve all the received Lisps, Arc, Bel to the ultimate lisp?
