This milestone decides whether the repository has a working, documented and presentable base on which the five challenges can be built: project configuration, ignore rules, package and test skeleton, source documentation, continuous integration, README and repository description with topics.
This milestone decides whether the first two challenges (Turtle Challenge 1, draw a square, and Turtle Challenge 2, draw a dashed line) work, are tested without a display and can be started from the command line, and whether the turtle abstraction that every later challenge relies on is sound.
This milestone decides whether Turtle Challenge 3 (draw different shapes, triangle to decagon, in random colors) works and whether the random_color helper from the tuple lecture is correct, because the random walk and the spirograph of the last milestone both depend on it.
This milestone decides whether the last two challenges (Turtle Challenge 4, generate a random walk, and Turtle Challenge 5, draw a spirograph) work and whether the whole repository is ready to be shared: all five challenges run, the README is complete and checked from a fresh clone, and every success criterion of the Business Case is met.
