+# Docker Compose
+
+## Run it on localhost
+
+Notifo needs https. This is a little bit tricky on localhost.
+
+### 1. Configure Caddy
+
+Caddy is used as a reverse proxy and also creates the certificates. Usually lets-encrypt is used for that, but for localhost we need to switch to a local certificate authority.
+
+Therefore you have to comment out the following line in `docker-compose.yml`:
+
+```yml
+# - SITE_SETTINGS="tls internal"
+```
+
+### Step 2 Download the root certificate
+
+Caddy usually installs the root certificate, but this is not available on docker. Therefore we have to install the root certificate manually. First download the certificate from the docker container:
+
+docker cp docker-compose-notifo_proxy-1:/data/caddy/pki/authorities/local/root.crt .
+
+Next install the certificate to the **trusted root authorities store**. You might need to restart chrome after that.
