+- [sbt](https://www.scala-sbt.org/download.html)
+- [Verilator](https://verilator.org/guide/latest/install.html)
+- A Java JDK
+
+More info can be found in the SpinalHDL
+[documentation](https://spinalhdl.github.io/SpinalDoc-RTD/master/SpinalHDL/Getting%20Started/getting_started.html).
+
+On Arch Linux, everything can be installed from the package repositories:
+
+```
+sudo pacman -S sbt verilator jdk-openjdk
+```
+
+The PCs in the CS department have everything installed.
+
+# Test installation
+
+To test code generation (this should create a file called `Counter.v`):
+
+```
+sbt 'runMain spinaltest.Gen'
+```
+
+To test simulation:
+
+```
+sbt 'runMain spinaltest.Sim'
+```
+
+This should print something like the following at the end:
+
+```
+[info] [Progress] Simulation workspace in /.../SpinalTest/./simWorkspace/Counter
