+# Trezor BLE Gateway
+
+Welcome to the **Trezor BLE Gateway** project!
+This repository contains the source code and instructions to build and flash the application onto the `t3w1_nrf52833` board.

+
+## Prerequisites
+
+Before you begin, ensure you have met the following requirements:
+
+- **nrfutil**: Install [nrfutil](https://docs.nordicsemi.com/bundle/nrfutil/page/README.html). This tool is essential for managing the nRF Connect SDK and toolchains.
+- **Git**: Ensure you have Git installed for cloning repositories.
+
+## Getting Started
+
+Follow these steps to set up the project on your local machine.
+
+### Install the toolchain
+
+Using nrfutil, install the required toolchain for the nRF Connect SDK:
+```sh
+nrfutil toolchain-manager install --ncs-version v2.6.2
+```
+
+### Launch the nRF Shell
+
+First, launch the nRF shell using the `nrfutil` toolchain manager:
+
+```sh
+nrfutil toolchain-manager launch --shell
+```
+
+### Initialize the Workspace
+Initialize your West workspace for the Trezor BLE Gateway project:
+```sh
+cd west
+west init -l ./trezor
+```
+
+### Update nRF Connect SDK Modules
+
+Update the modules:
+```sh
+west update
+```
+
+
+### Building the Application
+west build ./trezor-ble -b t3w1_revA_nrf52832 --sysbuild
+```
+
+Debug builds can be built using the debug overlay configuration:
+Build the application for the t3w1_revA_nrf52832 board:
+```sh
+cd trezor
+```sh
+west build ./trezor-ble -b t3w1_revA_nrf52832 --sysbuild -- -DOVERLAY_CONFIG=debug.conf
+```
+
+
+### Flashing the Application
+Flash the compiled application onto the board:
+```sh
+west flash
+```
