## ERDs
- ERDs will be written in the .er format using the [VScode ERD preview extension by kiashuu0123](https://github.com/kaishuu0123/vscode-erd/).
- This extension is simply a port to VScode of [BurntSushi's ERD schema for creating .er files](https://github.com/BurntSushi/erd), which is a wrapper for [graphviz's dot schema](https://www.graphviz.org/) (to my understanding).
