-## LaTeX
-
-The schema structure diagram is done with LaTeX. You can use a GUI like https://www.mathcha.io/editor to create the .tex file.
-
-Then use this command to generate the png file.
-
-```bash
-postgrest-docs-render
-```
-
-LaTeX is used because it's a tweakable plain text format.
-
-You can install the full latex suite with `nix`:
-
-```
-nix-env -iA texlive.combined.scheme-full
-```
-
-To tweak the file with a live reload environment use:
-
-```bash
-# open the pdf(zathura used as an example)
-zathura db.pdf &
-
-# live reload with entr
-echo db.tex | entr pdflatex --shell-escape -halt-on-error db.tex
-```

 ## UML
