 # simulsim
 Another attempt at a multiplayer framework.
+
+## Tests
+simulsim uses [busted](https://olivinelabs.com/busted/) for running tests, [LuaCOv](https://keplerproject.github.io/luacov/) for code coverage, and [Luacov-console](https://github.com/spacewander/luacov-console) for code coverage visualization.
+
+To get started, install all of the dependencies above using [LuaRocks](https://luarocks.org/):
+    luarocks install busted
+    luarocks install luacov
+    luarocks install luacov-console
+
+To run the unit tests:
+    busted ./tests
+
+To get a code coverage report:
+    luacov && luacov-console && luacov-console -s
+
