+## A Git, GitLab, and JUnit exercise
+
+This assignment is intended to give you a relatively small exercise to give you a little familiarisation working with Git, Gradle,
+JUnit, and JavaFX on a very small codebase - before you and your group do something much more exciting on the much larger
+class-wide project.
+
+The example code you have been given is a simple JavaFX "dots and boxes" game. It has a couple of known bugs in it
+(already commented for you - the task is not really in finding the bugs). Please note: your task **is not simply to fix the bugs**. 
+Your task is a series of steps that show you can work with git, gitlab, gradle, and junit.
+
+You will notice that this is a git repository, but it is provided to you just as a zip that you download.
+If you run `git status`, you should see that you are on branch `main`.
+
+Your tasks:
+
+1. Create a repository on gitlab.une.edu.au and push this code to it **entirely unmodified**. 
+   It will be on a branch called 'main'  
+   **You will need to set the visibility on your repository so that the marker can read from it**. 
+   Repositories we cannot access cannot be marked (and will receive 0 until you can fix it)
+   
+2. Set your name and email on the repository for your future commits, using `git config`
+
+3. Update the "name" label in the application to show **your name**.
+   Commit this change and push it to your **main** branch.
+
+3. Create an Issue in your GitLab project for fixing the errors in the assignment.
+4. Create and check out a branch for your bugfix. 
+   This should follow the convention of having the issue number, followed by a hyphenated description of the issue.
+   e.g. `1-fix-assignment-errors`.  
+   Push this branch to the remote repository. (From here on, I'll refer to this as your "issue branch")
+
+5. Create **unit tests** that will detect the errors in the code. Particularly:
+   * That the algorithm for testing whether a box is complete is wrong.
+   * That the DotsAndBoxesGrid currently permits you to "draw" a line that has already been drawn, whereas it should throw an exception.
+    
+6. Commit these unit tests with an appropriately descriptive commit message.  
+   **Do not fix the bugs in this commit. The unit tests should *fail*.**    
+
+7. **Tag** this commit, with the label `testsfail`
+
+8. Fix the bugs in the code. Run your unit tests again. The tests should now pass.
+
+9. Commit your bugfix. Push it to your issue branch.
+
+10. Check out `main`. Merge your issue branch to main. The tests should still pass. Push this to your gitlab repository.
+
+11. Close your issue with a reference to the commit hash in which you fixed the bugs.
+
+12. Paste the link to your gitlab repository into the assignment and submit.
+
+Marking. 
+
+1. You have submitted a link to your repository on gitlab.une.edu.au and it is visible to the marker (1 point)
+2. The first commit on the main branch on the repository contains the starter code, showing me as author and the same
+   commit hash as in the original code I gave you. (i.e. you successfully pushed the original code I gave you to your repository). (1 point)
+3. The second commit on the main branch adds your name to the label and shows you as author  
+   (i.e. you have successfully configured your name & email and you have successfully created and pushed a commit) (1 point)
+4. You have an issue on your repository for the bugfixing. It is closed referencing the bugfix commit. (1 point)
+5. There is a `testsfail` tag in your repository (1 point)
+6. Checking out the `testsfail` tag, and running the `gradlew test`, produces two failed tests (one for each bug). (2 points)
+7. Checking out the main branch, both tests are present and pass (2 points)
+8. The most recent commit on the `main` branch is a merge commit, merging the commit in which you set your name on the label
+   and the commit in which you fixed the tests. (1 point)

src/main/java/module-info.java

+/**
+ * This is a module file.
+ *
+ * Modules were introduced in Java 9, allowing modules to express dependencies on other modules and to publish their
+ * public packages.
+ *
+ * Using modules makes things easier when working with JavaFX, because JavaFX is itself published as a module.
+ *
+ * Please note: "module" in Java is not quite the same as "dependency" in Gradle. They are similar concepts, but
+ * "modules" is part of the Java language (but doesn't express how to find them on the internet) whereas
+ * "dependencies" is part of the Gradle build system and expresses how to find them on the internet (but does not
+ * specify the module imports to the Java compiler). We need both.
