 A Docker image is available on Docker Hub. The following command is enough to get a working server in development mode:
 
-    docker run \
-        -e MERCURE_PUBLISHER_JWT_KEY='!ChangeThisMercureHubJWTSecretKey!' \
-        -e MERCURE_SUBSCRIBER_JWT_KEY='!ChangeThisMercureHubJWTSecretKey!' \

+    -p 443:443 \

 The server is then available on `https://localhost`. Anonymous subscribers are allowed and the debugger UI is available on `https://localhost/.well-known/mercure/ui/`.
 
 In production, simply run:

 HTTPS support is automatically enabled. If you run the Mercure hub behind a reverse proxy [such as NGINX](cookbooks.md#using-nginx-as-an-http-2-reverse-proxy-in-front-of-the-hub), you usually want to use unencrypted HTTP.
 This can be done like that:
 
-    docker run \
-        -e SERVER_NAME=':80' \
-        -e MERCURE_PUBLISHER_JWT_KEY='!ChangeThisMercureHubJWTSecretKey!' \
-        -e MERCURE_SUBSCRIBER_JWT_KEY='!ChangeThisMercureHubJWTSecretKey!' \
-        -p 80:80 \
-        dunglas/mercure
+```console
+docker run \
+    -e SERVER_NAME=':80' \
+    -e MERCURE_PUBLISHER_JWT_KEY='!ChangeThisMercureHubJWTSecretKey!' \
