 ## File Sharing
 
+### Send

+
+    **Send** is a fork of Mozilla’s discontinued Firefox Send service which allows you to send files to others with a link. Files are encrypted on your device so that they cannot be read by the server, and they can be optionally password-protected as well. The maintainer of Send hosts a [public instance](https://send.vis.ee/). You can use other public instances, or you can host Send yourself.

+
+Send can be used via its web interface or via the [ffsend](https://github.com/timvisee/ffsend) CLI. If you are familiar with the command-line and send files frequently, we recommend using the CLI client to avoid JavaScript-based encryption. You can specify the `--host` flag to use a specific server:
+
+`‍``bash
+ffsend upload --host https://send.vis.ee/ FILE
+`‍``
