 Users of Debian-based systems (e.g. Ubuntu) can simply run the
 following to install the required dependencies:
 
 ```shell
 # apt-get update
-# apt-get install -y build-essential cmake jq wget pkg-config \
-    clang libclang-dev llvm-dev libudev-dev libfreetype6-dev \
-    libexpat1-dev
+# apt-get install -y git make jq gcc pkg-config openssl-dev
 ```
