+# JUCE Dependencies on Linux
+
+Below is a list of the current dependencies required to build JUCE projects on
+Ubuntu, separated by module. Where the dependency is optional, the preprocessor
+flag used to disable it is noted.
+
+This has been tested on Ubuntu 16.04 LTS (Xenial Xerus), 18.04 LTS (Bionic
+Beaver), and 20.04 LTS (Focal Fossa). Packages may differ in name or not be
+available on other distrubutions.
+
+## Compiler
+A C++ compiler is required. JUCE has been tested thoroughly with Clang and GCC:
+
+    sudo apt update
+    sudo apt install clang
+
+or
+
+    sudo apt update
+    sudo apt install g++
+
