(development note) How to update

Some .txt files in this repo are updated manually.
Some are updated programmatically:

## "The most developed loot management in video games"
# update the Google Spreadsheet
$ ruby loot.rb > loot.txt

## Rimworld textiles
# sort the <table> by name and copypaste from wiki to textiles.html
$ bundle exec ruby textiles.rb

## LoL TFT champions
$ bundle exec ruby lol.rb

## Ruby Web App Frameworks
$ bundle exec ruby ruby-web.rb

To preview the effect, according to main.yaml workflow:

$ ruby main.rb
$ yfm -i ./yfm -o ./out -s
$ open ./out/....html

Then after you push the .txt changes GitHub Action will automatically compile the single-page index.md, YFM docs and deploy them as GitHub Pages.
