+### Fly.io
+Fly.io lets you run an app with 512mb memory for free per month. Don't worry if you see your monthly bill going up, if it's less than $5, they will waive the cost.
+
+- Install flyctl by `brew install flyctl` or see other options at https://fly.io/docs/getting-started/launch/
+- Create an account with `fly auth signup` or log in with `fly auth login`.
+- `git clone https://github.com/redlib-org/redlib && cd redlib`
+- Edit fly.toml to configure your redlib instance
+- `fly deploy`
+- Go to https://replace-this-name.fly.dev and now you have your own redlib instance
+- To upgrade your instance to the latest build, run `fly deploy --image quay.io/redlib/redlib:latest`
