@@ -8,7 +8,7 @@ Nomad Network allows you to build private and resilient communications platforms
 
 Nomad Network is build on [LXMF](https://github.com/markqvist/LXMF) and [Reticulum](https://github.com/markqvist/Reticulum), which together provides the cryptographic mesh functionality and peer-to-peer message routing that Nomad Network relies on. This foundation also makes it possible to use the program over a very wide variety of communication mediums, from packet radio to fiber optics.
 
-Nomad Network does not need any connections to the public internet to work. In fact, it doesn't even need an IP or Ethernet network. You can use it entirely over packet radio, LoRa or even serial lines. But if you wish, you can bridge islanded networks over the Internet or private ethernet networks, or you can build networks running completely over the Internet. The choice is yours.
+Nomad Network does not need any connections to the public internet to work. In fact, it doesn't even need an IP or Ethernet network. You can use it entirely over packet radio, LoRa or even serial lines. But if you wish, you can bridge islanded networks over the Internet or private ethernet networks, or you can build networks running completely over the Internet. The choice is yours. Since Nomad Network uses Reticulum, it is efficient enough to run even over *extremely* low-bandwidth medium, and has been succesfully used over 300bps radio links.
 
 If you'd rather want to use an LXMF client with a graphical user interface, you may want to take a look at [Sideband](https://github.com/markqvist/sideband), which is available for Linux, Android and macOS.

+>>> Checkboxes
+
+In addition to text fields, Checkboxes are another way of submitting data. They allow the user to make a single selection or select multiple options. 
+
+`Faaa
+`=
+`<?|field_name|value`>`b Label Text`
+`=
+When the checkbox is checked, it's field will be set to the provided value. If there are multiple checkboxes that share the same field name, the checked values will be concatenated when they are sent to the node by a comma.
+``
+
+`B444`<?|sign_up|1`>`b Sign me up`
+
+You can also pre-check both checkboxes and radio groups by appending a |* after the field value.
+
+`B444`<?|checkbox|1|*`>`b Pre-checked checkbox`
+
+>>> Radio groups
+
+Radio groups are another input that lets the user chose from a set of options. Unlike checkboxes, radio buttons with the same field name are mutually exclusive.
+
+Example:
+
+`=
+`B900`<^|color|Red`>`b  Red
+
+`B090`<^|color|Green`>`b Green
+
+`B009`<^|color|Blue`>`b Blue
+`=
+
+will render:
+
+`B900`<^|color|Red`>`b  Red
+
+`B090`<^|color|Green`>`b Green
+
+`B009`<^|color|Blue`>`b Blue
+
+In this example, when the data is submitted, `B444` field_color`b will be set to whichever value from the list was selected.
