 # Lua Exercises
 
 This repo contains some Lua exercises along with automated tests for
-their solutions.  Each file contains a description of the problem and
-an area for your solution as well as the tests.  Feel free to define
-as many functions and constants as you need in the solution area, but
-do not modify the tests.  It's recommended that you roughly stick to
-the defined order of the exercises, but feel free to deviate if you
-wish.
+solutions.  Each file contains a description of the problem and an
+area for a solution as well as the tests.
+
+## Set Up
+
+To get started, create a fork of this repo on your own account, then
+clone it, passing the `--recursive` flag.  If you already cloned it
+without passing `--recursive`, you can run `git submodule update
+--init` to fix it.
+
+```sh
+git clone --recursive git@git.wip.sh:<your-username>/lua-exercises.git
+# or
+git clone git@git.wip.sh:<your-username>/lua-exercises.git
+git submodule update --init
+```
+
+## Doing the Exercises
+
+It's recommended that you roughly stick to the defined order of the
+exercises, but feel free to deviate if you wish.  Some of the
+exercises are relatively easy, whereas some of them (especially the
+last few) are quite challenging; do not be disheartened if solving a
+particular exercise takes you a long time, and feel free to ask for
+help in the Discord server if you feel you are stuck.
+
+You can define as many functions and constants as you need in the
+solution area.  You might find it useful to temporarily comment out
+some of the tests to work through the cases one by one (especially on
+the more complex exercises), but do not modify the test code other
+than this, and make sure all the cases are un-commented again before
+considering the exercise solved.
 
 To run the tests and check your solution for a given exercise, simply
 run `lua <the-file>`.  For example, if you were working on the
