 ### 2.1. Software Dependencies
 We may require a few dependencies to be able to compile and use the new modem and uploader scripts. Under Ubuntu/Debian/Raspbian, you can install the required packages using:
 ```
-$ sudo apt-get install cmake build-essential libusb-1.0-0-dev git python3-venv sox bc rtl-sdr libatlas-base-dev
+$ sudo apt-get install cmake build-essential libusb-1.0-0-dev git python3-venv python3-crcmod python3-requests python3-pip sox bc rtl-sdr libatlas-base-dev
 ```
 Under OSX, Macports or Homebrew should be able to provide the above packages, though they may be named slightly differently.
