+Exercises for the Julia track go in the `exercises` directory and should follow the following filename conventions:
 
 `exercises/<slug>/<slug>.jl` Skeleton for the function that is called by the test suite. Provide (abstract) parameter and return types to ensure compatibility with the test suite.
 
 `exercises/<slug>/runtests.jl` Test suite for the exercise. Group related tests using [testsets](http://docs.julialang.org/en/release-0.5/stdlib/test/#working-with-test-sets).
 
 `exercises/<slug>/example.jl` Example solution for the exercise. It should follow the [Julia Style Guide](http://docs.julialang.org/en/release-0.5/manual/style-guide/).
 
 Replace `<slug>` with the exercise slug of the exercise you're working on.
 
 See [Issue #2](https://github.com/exercism/xjulia/issues/2) for discussion on the structure.

+### Testing the example solutions
+Test your example solutions by running `julia runtests.jl` in the project directory. Specify exercise slugs as arguments to run only certain exercises: `julia runtests.jl <slug>`.
