+# Reverse proxy
+
+Caddy is used, details
+[here](https://github.com/DoTheEvo/selfhosted-apps-docker/tree/master/caddy_v2).</br>
+
+`Caddyfile`
+```
+umami.{$MY_DOMAIN} {
+  reverse_proxy umami:3000
+
+  log {
+      output file /data/logs/umami_access.log {
+          roll_size 20mb
+          roll_keep 5
+      }
+  }
+}
+```
+
+### - Run it all
+Restarting the Caddy container `docker container restart caddy` will kick in the changes. Give Caddy time to get certificates, check `docker logs caddy`.
+
+# First run
+
+Default login: `admin` // `umami`. Go and change the password straight away.
+
+# Trouble shooting
+
+Check umami logs `docker logs umami`.
+
+# Update

+
+Manual image update:
