+Environment and Standards
+=========================
+
+The verilog should be written to adhere to the sub-set of SystemVerilog 2012
+supported by Icarus verilog 11.0. CPUs should be written to assume that
+verilog files are compiled with `-g 2012`, and test-benches should also
+provide that flag when compiling.
+
+The test environment should be assumed to be Ubuntu 18.04. Version 11.0
+of Icarus verilog is already compiled and installed. Standard base Ubuntu
+packages will be installed, along with the following packages:
+
+- `build-essential` (g++, make)
+- `git`
+- `gcc-mips-linux-gnu`
+- `qemu-system-mips`
+- `python3`
+- `cmake`
+- `verilator`
+- `libboost-dev`
+- `parallel`
