 # Asteroids
 
+`BodgeMaster was here.`
+
+I set up web deployment for you. Still need to take care of the reverse
+proxy side of things, but the deployment should already be working.
+
+
+## About the files I added:
+
+[deployment-script.sh](./deployment-script.sh) is being executed every time
+the updated project gets deployed. Deployment happens when you push
+to master. If you don’t need it, just leave it alone; deployment will fail
+without it.
+
+[webroot/](./webroot/) is the directory that is linked into the web server.
+You can either just put your files in there, or you can have the deployment
+script or some build process called by the deployment script put them there.
