 summary: How can I Self-Host Piped?
 ---
 
+# Self-Hosting
+
+There are two simple ways to self-host Piped.
+
+- [Bring your own reverse proxy](#docker-compose-nginx-aio-script) (**recommended**) - This is the recommended way to self-host Piped. You can use any reverse proxy you want, and must configure TLS certificates yourself.
+- [Using Caddy](#docker-compose-caddy-aio-script) - This would use Caddy on port 80 and 443, and automatically configure TLS certificates for you. However, it would be difficult to host multiple services on the same server.

+Here's an example with Apache:
+```
+<VirtualHost *:443>
+    ServerName hostname # For all 3 hostnames
+
+    ProxyPass /  http://127.0.0.1:8080/  nocanon

+```

+Here's an example with Traefik using Docker compose labels:
+
+This must be applied on the nginx container.
+
+```
+labels:
+  - "traefik.enable=true"
+  - "traefik.http.routers.piped.rule=Host(`hostname`,`hostname2`,`hostname3`)"
+  - "traefik.http.routers.piped.entrypoints=web"
+```
+
+Here's an example using Caddy:
+
+```
+hostname, hostname2, hostname3 {
+    reverse_proxy http://127.0.0.1:8080
+}
+```
+
+
+Finally, configure your TLS certificates if necessary. For nginx, you could use certbot with the nginx plugin.
