+# fake-sys directory
+The tests require the fake-sys directory which comes from
+https://github.com/ddemidov/ev3dev-lang-fake-sys
+
+If you have already cloned the ev3dev-lang-python repo but do not have the
+`fake-sys` directory use `git submodule init` to get it.  If you have not
+already cloned the ev3dev-lang-python repo you can use the `--recursive` option
+when you git clone.  Example:
+
+```
+$ git clone --recursive https://github.com/rhempel/ev3dev-lang-python.git
+```
+
+# Running Tests
+To run the tests do:
+```
+$ ./api_tests.py
+```
+
+# Misc
 Commands used to copy the /sys/class node:
 
-```sh
-node=lego-sensor/sensor0
-mkdir -p ./${node}
-# Copy contents of special files, do not follow symlinks:
-cp -P --copy-contents -r /sys/class/${node}/* ./${node}/
+```
+$ node=lego-sensor/sensor0
+$ mkdir -p ./${node}
+$ cp -P --copy-contents -r /sys/class/${node}/* ./${node}/
