+# What is this?
+
+Traefik hogs your ports `80` and `443` (and others), will intercept HTTP requests to your server and forward them to different endpoints.
+
+It allows you to run multiple web services on the same IP address and access them on a domain name basis.
+
+We use both the Docker backend and a manual routing backend.
+
+# Requirements
+To make it easier to have multiple `docker-compose.yml` without having to specify networks by hand, we use Traefik natively installed on the host, rather than the usual Docker install.
+
+This allows it to access all Docker networks by default. 
+
+On NixOS:
+
+```
+    traefik = {
+      enable = true;
+      group = "docker";
+      configFile = "/var/lib/traefik/traefik.toml";
+    };
+```
