 - Make sure to open the compiled story file as a binary file (see the above example, use `open(filename, 'rb')`) in order for it to be properly parsed by the compiled protobuf library.
 - Unless you pass `autostart=False` to the runner when creating it, it will automatically start and run to the next choice point.

+As of version v0.0.2, all Yarn Spinner 1 opcodes are currently implemented, as well as Yarn Spinner 1's internal standard library of functions and operators. This may certainly change over time, if new opcodes, functions, or operators are added to the language. The current missing features are:

 The source code of the examples are located inside `*.yarn` files. `*.csv` and `*.yarnc` files are generated via the Yarn Spinner compiler. To compile these files, follow the below steps:
 
-1. Install the [Yarn Spinner Console](https://github.com/YarnSpinnerTool/YarnSpinner-Console) program `ysc`. Basic binaries are available on [their releases page](https://github.com/YarnSpinnerTool/YarnSpinner-Console/releases).
-2. From the `examples/` directory, run `ysc compile [filename].yarn`. For example, to compile the basic example used in `tests/test_basic.py`, use `ysc compile basic.yarn`.

 Currently `*.csv` and `*.yarnc` files are committed to version control to make it easier to run our test suite. They will likely be gitignored later once we have a better build process for these files.
