@@ -6,18 +6,12 @@ a simple PUS (CCSDS) interface to update the software. It also provides a Python
 called the `image-loader.py` which can be used to upload compiled images to the flashloader
 application to write them to the NVM.
 
-Please note that the both the application and the image loader are tailored towards usage
-with the [bootloader provided by this repository](https://egit.irs.uni-stuttgart.de/rust/va416xx-rs/src/branch/main/bootloader).
-
 The software can quickly be adapted to interface with a real primary on-board software instead of
 the Python script provided here to upload images because it uses a low-level CCSDS based packet
 interface.
 
 ## Using the Python image loader
 
-The Python image loader communicates with the Rust flashload application using a dedicated serial
-port with a baudrate of 115200.
-
 It is recommended to run the script in a dedicated virtual environment. For example, on UNIX
 systems you can use `python3 -m venv venv` and then `source venv/bin/activate` to create
 and activate a virtual environment.

 # [unreleased]
 
-# [v0.3.0] 2024-30-09
-
 ## Changed
 
 - Improve and fix SPI abstractions. Add new low level interface. The primary SPI constructor now
   only expects a configuration structure and the transfer configuration needs to be applied in a
   separate step.
-- Added an additional way to read the UART RX with IRQs. The module documentation provides
-  more information.
-- Made the UART with IRQ API more flexible for future additions.
-- Improved UART API result and error handling, added low level API to read from and write
-  to the FIFO directly

 # Rust BSP for the Vorago PEB1 development board
 
-This is the Rust **B**oard **S**upport **P**ackage crate for the Vorago PEB1 development board.
+## Using the `.cargo/config.toml` file
-Its aim is to provide drivers for the board features of the PEB1 board.
 
-The BSP builds on top of the [HAL crate for VA416xx devices](https://egit.irs.uni-stuttgart.de/rust/va416xx-rs/src/branch/main/va416xx-hal).
+Use the following command to have a starting `config.toml` file
+
+```sh
+cp .cargo/def-config.toml .cargo/config.toml
+```
+
+You then can adapt the `config.toml` to your needs. For example, you can configure runners
+to conveniently flash with `cargo run`.
