+## Raw Credentials
+If passing the contents of the HTPASSWD file is not convenient for you (because
+you need to perform additional step of generating it via `htpasswd -nb foo
+bar`), you can pass the credentials in a raw form and the contents of HTPASSWD
+variable will be generated for you. The `RAW_CREDENTIALS=1` must be set to
+enable this feature.
