 # Pilkki
 SWD flashing tool for EFM32 microcontrollers.
 
 ## Project structure
 
-Utility to interact with flasher could be found in [software](software) folder.
+The project is divided into three parts:
+
+1. **[Software](software)**: The flashing utility.
+2. **[Electronics](electronics)**: Schematics and PCB (KiCAD).
+3. **[Firmware](firmware)**: Firmware for the target device.
+
+### How to Use
 
-To use flasher, call `cargo run`, or build by `cargo build --release`
+To use the flasher, you can either:
 
-Schematics and PCB (KiCAD) are in [electronics](electronics) folder.
+- Run the utility directly with `cargo run`
+- Build the project in release mode with `cargo build --release`
 
-Firmware sources are [here](firmware)
+More info on how to use pilkki in [Readme.md](software/Readme.md) in the [Software](software) section

+# Pilkki Software
+This folder contains the utility to interact with the flasher.
+
+## How to Use
+
+To run the flashing tool:
+- Use `cargo run` to run the tool.
+- Use `cargo build --release` to build the release version.
+
+The utility should automatically detect the connected port; otherwise, you can specify it manually with the `--port` flag.
+
+### Getting help
+```sh
+cargo run -- help
+```
+
+### Finding the Port to Which Your Device Is Connected:
+
+**Linux:**
+```sh
+ls /dev/ttyUSB*
+```
+
+**MacOS:**
+```sh    
+ls /dev/tty.* /dev/cu.*
+```
+
+### Verify Connection to the Device
+
+To connect to the device, run:
+```sh
+cargo run -- --port /port/address connect
+```
+
+### Flash a New Binary:
+
+To flash a new binary to the device:
+```sh
+cargo run -- write --input /path/to/your/binary.bin
+```
+Or, if you need to specify the port manually:
+```sh
+cargo run -- write --port /port/address --input /path/to/your/binary.bin
+```
+
+### Getting the Firmware Binary
+
+You can either:
+- Build the binary using the code from the [kampela-firmware](https://github.com/Kalapaja/kampela-firmware) repository.
+- Download the compiled binary from the [releases](https://github.com/Kalapaja/kampela-firmware/releases) section.
