Install dependencies: asciidoctor.
Run make to produce build/tutorial.html and its dependencies: especially, build/exercises/*.c and build/solutions/*c.
Run make check-tutorial to check that all examples in the tutorial have working solutions (except tests with names *.broken.c, which are expected to fail). Note that this step will not work until after you have installed CN, which is the first part of the tutorial.
Run make check to checks both the tutorial and archive examples (see below).
The subdirectory src/example-archive includes many more examples of CN proofs, both working and broken. See the README for a description how these examples are organized.
Run make check-archive to check all examples in the example archive.
