# About the project
This simple shortlink server targets portable network devices and other low-performance machines.
It comes in form of AMD64 Docker Image, but you can use it on any other platform (tested natively on MacOS 26.0.1 Tahoe) and without Docker.
# Set up
Before launching the program:
- perform database migrations (in `./migrations` directory) manually or with your favourite tool;
- change Postgres password in `docker-compose.yml` and `.env`;
- change API_KEY to **LONG AND SECURE STRING** in `.env`.
