         This runs our register pre-commit hooks on every commit to automatically point out issues in code such as missing semicolons, trailing whitespace, and debug statements. By pointing these issues out before code review, this allows a code reviewer to focus on the architecture of a change while not wasting time with trivial style nitpicks.
 
+### PostgreSQL setup
+
+Install PostgreSQL according to its [documentation](https://www.postgresql.org/download/).
+
+Enter psql, a terminal-based front-end to PostgreSQL:
+
+<div class="termy">
+
+```console
+$ psql -qd postgres
+```
+
+Run the following queries to create the user and database:
+
+```psql
+CREATE USER voting WITH SUPERUSER PASSWORD 'modmail';
+CREATE DATABASE modmail WITH OWNER modmail;
+```
+
+Finally, enter `/q` to exit psql.
+
+Once the Database is started, you need run migrations to init tables and columns which can be ran through:
+
+<div class="termy">
+
+```console
+$ poetry run alembic upgrade heads
+
+---> 100%
+```
