+## Compiling and flashing
+
+Install the complete toolchain and utils:
+
+```shell
+curl https://sh.rustup.rs -sSf | sh
+rustup target add thumbv6m-none-eabi
+rustup component add llvm-tools-preview
+cargo install cargo-binutils
+sudo apt-get install dfu-util
+```
+
+Compile:
+
+```shell
+cd firmware
+cargo objcopy --bin keyseebee --release -- -O binary keyseebee.bin
+```
+
+To flash using dfu-util, first put the board in dfu mode by pressing
+BOOT, pressing and releasing RESET and releasing BOOT. Then:
+
+```shell
+dfu-util -d 0483:df11 -a 0 -s 0x08000000:force:unprotect:leave -D keyseebee.bin
+```
