The `LabConnections.jl` package is subdivided into two main modules; `Computer`
and `BeagleBone`. `Computer` defines the user interface on the host
computer side, while `BeagleBone` defines low-level types and functions meant

## Getting Started
### Installation
-Instructions on installing the required software and setting up a connection between
-the host computer and the BBB are found [here](https://gitlab.control.lth.se/labdev/LabConnections.jl/blob/julia1/docs/build/man/installation.md#installation-instructions).
+First, you should follow the instructions on how to install the required software and setting up a connection between the host computer and the BB. These instructions are found [here](https://gitlab.control.lth.se/labdev/LabConnections.jl/blob/julia1/docs/build/man/installation.md#installation-instructions).
### A Simple Example
-We will here go through a simple example of using the host computer interface to communicate with the BBB and control the onboard system LEDs.
+This is a simple example that demonstrates the usage of local devices on the BB via a host computer. The devices that will be used in the example are `SysLED` and `GPIO`.
-First make sure that you have followed the installation guide, and that the BBB is running a server and is connected to the host computer.
