1. Download docker-compose.yml to dir named sentry
2. Change SENTRY_SECRET_KEY to random 32 char string
3. Run docker-compose up -d
4. Run docker-compose exec sentry sentry upgrade to setup database and create admin user
5. (Optional) Run docker-compose exec sentry pip install sentry-slack if you want slack plugin, it can be done later
6. Run docker-compose restart sentry
7. Sentry is now running on public port 9000

remap prefix to Control + a
