-This repository contains a Zephyr example application. The main purpose of this
-repository is to serve as a reference on how to structure Zephyr-based
-applications. Some of the features demonstrated in this example are:
-
-- Basic [Zephyr application][app_dev] skeleton
-- [Zephyr workspace applications][workspace_app]
-- [Zephyr modules][modules]
-- [West T2 topology][west_t2]
-- [Custom boards][board_porting]
-- Custom [devicetree bindings][bindings]
-- Out-of-tree [drivers][drivers]
-- Out-of-tree libraries
-- Example CI configuration (using Github Actions)
-- Custom [west extension][west_ext]
-- Doxygen and Sphinx documentation boilerplate
-
-This repository is versioned together with the [Zephyr main tree][zephyr]. This
-means that every time that Zephyr is tagged, this repository is tagged as well
-with the same version number, and the [manifest](west.yml) entry for `zephyr`
-will point to the corresponding Zephyr tag. For example, the `example-application`
-v2.6.0 will point to Zephyr v2.6.0. Note that the `main` branch always
-points to the development branch of Zephyr, also `main`.

 ## Getting Started
 
-Before getting started, make sure you have a proper Zephyr development
-environment. Follow the official
-[Zephyr Getting Started Guide](https://docs.zephyrproject.org/latest/getting_started/index.html).
