-To compile this project firstly initialize and update the submodules: 
+First, clone the repository:
+```
+git clone https://github.com/raspberrypi/debugprobe
+cd debugprobe
+```
+Initialize and update the submodules:
 ```
  git submodule update --init
 ```
-then create and switch to the build directory:

-then run cmake and build the code:
+If your environment doesn't contain `PICO_SDK_PATH`, then either add it to your environment variables with `export PICO_SDK_PATH=/path/to/sdk` or add `PICO_SDK_PATH=/path/to/sdk` to the arguments to CMake below.
+
+Run cmake and build the code:
 ```
  cmake ..
  make
 ```
 Done! You should now have a `debugprobe.uf2` that you can upload to your Debug Probe via the UF2 bootloader.
 
-If you want to create the version that runs on the Raspberry Pi Pico, then you need to invoke `cmake` in the sequence above with the `DEBUG_ON_PICO=ON` option:
