+## Running tests
+
+In order to run the tests, issue the following command from the exercise
+directory:
+
+For running the tests provided, `rebar3` is used as it is the official build and
+dependency management tool for erlang now. Please refer to [the tracks installation
+instructions](http://exercism.io/languages/erlang/installation) on how to do that.
+
+In order to run the tests, you can issue the following command from the exercise
+directory.
+
+```bash
+$ rebar3 eunit
+```
+
+### Test versioning
+
+Each problem defines a macro `TEST_VERSION` in the test file and
+verifies that the solution defines and exports a function `test_version`
+returning that same value.
+
+To make tests pass, add the following to your solution:
+
+```erlang
+-export([test_version/0]).
+
+test_version() ->
+  1.
+```
+
+The benefit of this is that reviewers can see against which test version
+an iteration was written if, for example, a previously posted solution
+does not solve the current problem or passes current tests.
+

+This covers the basic information on setting up the development
+environment expected by the exercises.
