 As a best-in-class RTOS, Zephyr™ brings many [benefits](https://www.zephyrproject.org/benefits) to ZMK, such as:
 
-- A _single_ platform [supporting](https://docs.zephyrproject.org/latest/boards) many architectures, processors and boards.
+- A _single_ platform [supporting](https://docs.zephyrproject.org/latest/boards/index.html) many architectures, processors and boards.
 - Optimization for low-powered, small memory footprint devices.
-- Powerful hardware abstraction and configuration using [DeviceTree](https://docs.zephyrproject.org/latest/guides/dts/index.html) and [Kconfig](https://docs.zephyrproject.org/latest/guides/kconfig/index.html).
-- A BLE stack that periodically obtains [qualification](https://docs.zephyrproject.org/latest/guides/bluetooth/bluetooth-qual.html) listings, making it easier for final products to obtain qualification from the Bluetooth® SIG.

 - A buzzing developer [community](https://github.com/zephyrproject-rtos/zephyr) including many leading [embedded technology](https://www.zephyrproject.org/project-members) companies.

 - The name of the combo doesn't really matter, but convention is to start the node name with `combo_`.

-- `timeout-ms` is the number of milliseconds that all keys of the combo must be pressed.
+- `timeout-ms` is the length of the window (in milliseconds) in which all keys of the combo must be pressed in order to successfully trigger the combo.
 - `key-positions` is an array of key positions. See the info section below about how to figure out the positions on your board.
 - `layers = <0 1...>` will allow limiting a combo to specific layers. This is an _optional_ parameter, when omitted it defaults to global scope.
 - `bindings` is the behavior that is activated when the behavior is pressed.
