+# Migrations
+
+## How do I write a migration file?
+
+[See here](https://bun.uptrace.dev/guide/migrations.html#migration-names)
+
+As a template, take one of the existing migration files and modify it. It will be automatically loaded and handled by Bun.
+
+## File format
+
+Bun requires a very specific format: 14 digits, then letters or underscores.
+
+You can use the following bash command on your branch to generate a suitable migration filename.
+
+```bash
+echo "$(date --utc +%Y%m%H%M%S%N | head -c 14)_$(git rev-parse --abbrev-ref HEAD).go"
+```
+
+## Rules of thumb
+
+1. **DON'T DROP TABLES**!!!!!!!!
