  The Astrophysics Source Code Library (ASCL) contains 3000 metadata records
about astrophysics research software and serves primarily as a registry of
software, though it also can and does accept code deposit. Though the ASCL was
started in 1999, many astronomers, especially those new to the field, are not
very familiar with it. This hands-on virtual tutorial was geared to new users
of the resource to teach them how to use the ASCL, with a focus on finding
software and information about software not only in this resource, but also by
using Google and NASA's Astrophysics Data System (ADS). With computational
methods so important to research, finding these methods is useful for examining
(for transparency) and possibly reusing the software (for reproducibility or to
enable new research). Metadata about software is useful for, for example,
knowing how to cite software when it is used for research and studying trends
in the computational landscape. Though the tutorial was primarily aimed at new
users, advanced users were also likely to learn something new.
