+# Deploying a babashka app to fly.io
+
+[Fly.io](https://fly.io/) is a service that can run full stack apps with minimal
+configuration. If you like the ease of Heroku, you might like fly.io and perhaps
+even better! This document shows how to get a minimal babashka application up
+and running on `fly.io`.
+
+In `example.clj` we start an http-kit web server which spits out some HTML. You
+can run this locally by invoking `bb example.clj` from the command line.
+
+To get this site running on `fly.io`, you need to
+[install](https://fly.io/docs/getting-started/installing-flyctl/) and [log
+in](https://fly.io/docs/getting-started/log-in-to-fly/).
+
+Then run `flyctl launch` to create a new application. After making changes, you
+can re-deploy the site with `flyctl deploy`.
+
+That's it!
