+- `SEND2GOKAPI_URL`: Base URL of a Gokapi instance. For example: `https://your.gokapi.url/`.
+- `SEND2GOKAPI_API_KEY`: API Key
+
+```shell
+send2gokapi [OPTIONS] FILES
+```
+
+Valid options:
+
+- `-d`: Max number of downloads allowed for each uploaded file (0 = unlimited). Default is 5 
+- `-t`: Number of days to keep files (0 = unlimited). Default is 7.
