 ## Environment variables
 
-### Common
-
 - `DEBUG=1` - show debug and verbose logs, set in any value
 - `WHATSAPP_API_PORT=3000` - listen port for HTTP server (default: `3000`)
 - `WHATSAPP_API_HOSTNAME=localhost` - Hostname for HTTP server (default: `localhost`)
 - `WHATSAPP_API_KEY=mysecret` - protect the api with a secret code. If you set it - add `X-Api-Key: mysecret` to all
   requests.
-- `WHATSAPP_SWAGGER_USERNAME=admin` + `WHATSAPP_SWAGGER_PASSWORD=admin` - protect the Swagger panel with `admin / admin` credentials. It doesn't affect api access!

 ## File storage ![](/images/versions/plus.png)
+
 - `WHATSAPP_FILES_MIMETYPES` - download only these mimetypes from messages (download all files be default). Mimetypes
   must be separated by a comma, without spaces: `audio,image/png,image/gif`. In order to choose type use prefix (
   like `audio,image`).
 - `WHATSAPP_FILES_LIFETIME`- to keep free space files will be removed after this time (default: `180`, in seconds)
 - `WHATSAPP_FILES_FOLDER` - folder where will be stored files from chats (images, voice messages) (
   default: `/tmp/whatsapp-files`)

+## Engines
