+Runs the `make.jl` script and serves the docs on `localhost:8000`.
+You have to have `Revise` and `LiveServer` in your global environment for this script to work.
+
+Two modes available:
+- Full mode (default): Builds complete docs with examples, prompts to rebuild after each run
+- Draft mode (--draft): Uses Documenter's draft mode with automatic rerendering, skips examples
+
+The script will prompt whether to update the docs environment (10 second timeout, defaults to No).
+At the end of each full build run, the user is prompted to rerun the make process. Using Revise
+this will use updated `*.md` and source files, keeping the Julia session alive for faster builds.
