Make changes, and test them by running:
make
This will run go run main.go examples/slides.md, you can then ensure
everything still works.
If you're adding a feature that requires a specific piece of markdown, you can
add a file with your test case into examples/<test>.md and iterate on that file.
Ensure tests are still passing
make test
Most changes should be entirely backwards compatible.
Ensure that slides examples/slides.md still works.
Initialization (command-line interface, defaults) happens in cmd/root.go.
Interaction (controls, input, output) happens in model.go
Optional configuration (e.g. theme: dark) can be added to meta.go
