+Contributing
+============
+
+Thank you for your interest in contributing to Quests! We appreciate your 
+effort, but to make sure that the inclusion of your patch is a smooth process, we
+ask that you make note of the following guidelines.
+
+* **Target Java 16 for source and compilation.** Make sure to mark methods with
+  ` @Override` that override methods of parent classes, or that implement
+  methods of interfaces.
+* **Use only spaces for indentation.** Our indents are 4-spaces long, and tabs
+  are unacceptable.
+* **Wrap code to a 120 column limit.** We do this to make side by side diffs
+  and other such tasks easier. Ignore this guideline if it makes the code
+  too unreadable.
+* **Write complete Javadocs.** Do so only for public methods, and make sure
+  that your `@param` and `@return` fields are not just blank.
+* **Don't tag classes with @author.** Some legacy classes may have this tag,
+  but we are phasing it out.
+* **Make sure the code is efficient.** One way you can achieve this is to spend
+  around ten minutes to think about what the code is doing and whether it
+  seems awfully roundabout. If you had to copy the same large piece of
+  code in several places, that's bad.
+* **Keep commit summaries under 70 characters.** For more details, place two
+  new lines after the summary line and write away!
+* **Test your code.** We're not interested in broken code, for the obvious reasons.
+
+
+Branches
+----------------
+When submitting a feature or bugfix, base your code on the newest development branch,
+and PR against that same branch. If such a branch does not exist, base your code
+against the `master` branch, and PR against that same branch.
+
+
+Checklist
+---------
+
+Ready to submit? Perform the checklist below:
+
+1. Have all tabs been replaced into four spaces? Are indentations 4-space wide?
+2. Have I written proper Javadocs for my public methods? Are the @param and
+   @return fields actually filled out?
+3. Have I run [`git rebase`](https://docs.github.com/github/getting-started-with-github/about-git-rebase) to the latest commit of the target branch?
+4. Have I combined my commits into a reasonably small number (if not one)
+   commit using [`git rebase`](https://docs.github.com/github/getting-started-with-github/about-git-rebase)?
+5. Have I made my pull request too large? Pull requests should introduce
+   small sets of changes at a time. Major changes should be discussed with
+   other contributors prior to starting work.
+6. Are my commit messages descriptive?
+
+Example
+-------
+
+This is **GOOD:**
+
+    if (var.func(param1, param2)) {
+        // do things
+    }
+
+This is **BAD:**
+
+    if(vAR.func( param1, param2 ))
+        //do things
