 ### Flashing
 
+#### Easier way
+
+```shell
+# download binary from https://files.m-labs.hk/s/DcJwdC33tyBK7at
+nix-shell -p dfu-util
+dfu-util -a 0 -s 0x08000000:leave --download booster0.5.0.bin
+```
+
+#### Build from source on Fedora 38
+
+Creating proper Nix shell for updated Rust is quite troublesome, so the faster way is actually to use any
+classic Linux distribution:
+
+```shell
+git clone https://github.com/quartiq/booster.git # download sources
+sudo dnf install clang dfu-util
+cd booster/
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh # install Rust, we need rustup
+rustup target add thumbv7em-none-eabihf
+cargo install cargo-binutils
+rustup component add llvm-tools-preview
+cargo build --release
+cargo objcopy --release -- -O binary booster.bin
+# enter dfu mode by either serial terminal or
+# press `DFU Bootloader` button while rebooting
+dfu-util -a 0 -s 0x08000000:leave --download booster.bin
+```
+
+#### For version before September 2023 on NixOS
+
 ```shell
 git clone git@github.com:quartiq/booster.git
 cd booster
+git checkout f7d89f4d9d7760e8bc73ec13f17212512b60af15 # or earlier
