+Usage
+-----
+
+.. highlight:: make
+
+This folder contains a Makefile with several recipes, most of which are aliases to ``dotnet`` commands.
+This facilitates the root Makefile dispatching tasks to each language, many of which have more complex
+build or test processes.
+
+.. make:target:: test
+
+ Alias for ``maven test -Dtest.single``.
+
+.. make:target:: test_auto
+
+ .. note::
+
+ WIP
+
+ Runs tests in parallel with one less thread than you have CPUs. Alias for ``maven test-T 1C``.
+
+.. make:target:: test_%
+
+ .. note::
+
+ WIP
+
+ Runs tests in parallel with the specified number of threads. Alias for ``maven test -T $*``.
+
+.. make:target:: clean
+
+ Alias for ``maven clean``, with some degree of fallback if ``maven`` is not installed.
+
+.. make:target:: lint
+
+ Alias for ``maven formatter:format``.

+Java Section
+============
+
+.. |Java Check| image:: https://github.com/LivInTheLookingGlass/Euler/actions/workflows/java.yml/badge.svg
+ :target: https://github.com/LivInTheLookingGlass/Euler/actions/workflows/java.yml
+
+|Java Check|
+
+All problems are solved in Java 8+.
+
+Organization
+------------
+
+All Java files share a common prefix with their problem number. All shared
+functions are defined in the include folder.
+
+Makefile
+--------
+
+There are three main recipes in this Makefile
+
+dependencies
+~~~~~~~~~~~~
+
+This recipe installs all the required and test dependencies. See the
+Dependencies section for more info
+
+test
+~~~~
+
+This recipe runs tests in multiple threads
+
+lint
+~~~~
+
+This recipe runs ``maven``\ s builtin formatter
+
+Tests
+-----
+
+Prime Infrastructure Test
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This test checks five things:
+
+1. It checks ``is_prime()`` for numbers up to ``MAX_PRIME``, where that
+ is defined in the test
+2. It checks that ``is_composite()`` returns truthy values on composites
+ in that range, and falsey values on primes
+3. It checks that ``is_composite()`` returns the smallest prime factor
+ on composite numbers
+4. It checks that the prime numbers are generated in the correct order
+5. It checks that all these operations are completed in less than 200ns
+ \* ``MAX_PRIME``
+
+Generic Problems
+~~~~~~~~~~~~~~~~
+
+For each problem it will check the answer against a known dictionary. If
+the problem is not in the "known slow" category (meaning that I generate
+the correct answer with a poor solution), it will always be run.
+Otherwise it tries to detect the ``NO_SLOW`` environment variable and
+dynamically skip them.
+
+A test fails if it gets the wrong answer or if it takes more than 1
+minute.
+
+Dependencies
+------------
+
+I try to keep the dependencies of this project as small as possible,
+except for test plugins. At the moment there are no non-test
+dependencies for this section.
