 This is the reference API for the JavaScript script engine, along with default property values.
 Other script engines may vary in their syntax (e.g. `args.inputs[i][j]` vs `args.getInput(i, j)` vs `input(i, j)`), but the functionality should be similar.

-### Adding a script engine
+## Adding a script engine
 
 - Add your scripting language library to the build system so it builds with `make dep`, following the Duktape example in the `Makefile`.
-- Create a `MyEngine.cpp` file (for example) in `src/` with a `ScriptEngine` subclass defining the virtual methods, following `src/DuktapeEngine.cpp` as an example.
+- Create a `MyEngine.cpp` file (for example) in `src/` with a `ScriptEngine` subclass defining the virtual methods, possibly using `src/DuktapeEngine.cpp` as an example.
 - Add your engine to the "List of ScriptEngines" in `src/ScriptEngine.cpp`.
 - Build and test the plugin.
 - Add a few example scripts and tests to `examples/`. These will be included in the plugin package for the user.
 - Add your name to the Contributers list below.
 - Send a pull request. Once merged, you will be added as a repo maintainer. Be sure to "watch" this repo to be notified of bugs in your engine.
