Abstract
In this article, we document version 0.1 of the PanScales code for parton shower simulations. With the help of a few examples, we discuss basic usage of the code, including tests of logarithmic accuracy of parton showers. We expose some of the numerical techniques underlying the logarithmic tests and include a description of how users can implement their own showers within the framework. Some of the simpler logarithmic tests can be performed in a few minutes on a modern laptop. As an early step towards phenomenology, we also outline some aspects of a preliminary interface to Pythia, for access to its hard matrix elements and its hadronisation modules.

List of changes
- section 1:
* added references to a selection of papers on hadronisation and tuning
- section 2.1:
* addition of outline of directory structure
- section 2.2:
* added reference to new Appendix A, mentioning in particular access to step-by-step event record
- section 2.4:
* added indication that one needs to install the CT14lo set
* added a paragraph at the end of the section, with a discussion of the interplay between hadronisation and logarithmic accuracy
- section 2.5:
* added mention of the use of Catch2 library for unit tests
- section 3.1:
* added discussion of the choice of $\alpha_s$ values for the global event-shape logarithmic accuracy tests
- section 3.1.1:
* (penultimate paragraph) added discussion of the approximate observable that is used as a helper within log-accuracy tests
- section 3.1.3:
* substantial rewrite of this section (on weighted event generation
for $\beta_{ps}\neq \beta_{obs}$), to help make it clearer
- section 3.2:
* updated footnote 9 discussing leading-$N_C$ colour choices in the tests
of non-global logarithms
- Appendix A:
* added new appendix with event record description
