 To build:
 * nginx first because it creates selfsigned certificate:
-  docker-compose -f sourcearcade.yml build --build-arg SELFSIGNED_REQ_HOST=hostname nginx
+  docker-compose build --build-arg SELFSIGNED_REQ_HOST=hostname nginx
   - optionally: --build-arg SELFSIGNED_REQ_ALT_NAMES="DNS:name1 ..."
-* docker-compose -f sourcearcade.yml build --build-arg SELFSIGNED_REQ_HOST=hostname
+* docker-compose build --build-arg SELFSIGNED_REQ_HOST=hostname
   - same build-args!
 
 Create environment files (cf. `git ls-files \*environment.template`):
 * Set SA_PUBLIC_DOMAIN_NAME in `environment`
 * Set CANONICAL_WEB_URL in `gerrit/environment`
 * Enable GitHub OAUTH in `gerrit/environment`
+
+Get containers up:
+* `docker-compose up`
