  Mumford showed that Schottky subgroups of $PGL(2,K)$ give rise to certain
curves, now called Mumford curves, over a non-Archimedean field K. Such curves
are foundational to subjects dealing with non-Archimedean varieties, including
Berkovich theory and tropical geometry. We develop and implement numerical
algorithms for Mumford curves over the field of p-adic numbers. A crucial and
difficult step is finding a good set of generators for a Schottky group, a
problem solved in this paper. This result allows us to design and implement
algorithms for tasks such as: approximating the period matrices of the
Jacobians of Mumford curves; computing the Berkovich skeleta of their
analytifications; and approximating points in canonical embeddings. We also
discuss specific methods and future work for hyperelliptic Mumford curves.
