  We introduce Rosetta, a program allowing for the translation between
different bases of effective field theory operators. We present the main
functions of the program and provide an example of usage. One of the
Lagrangians which Rosetta can translate into has been implemented into
FeynRules, which allows Rosetta to be interfaced into various high-energy
physics programs such as Monte Carlo event generators. In addition to popular
bases choices, such as the Warsaw and Strongly Interacting Light Higgs bases
already implemented in the program, we also detail how to add new operator
bases into the Rosetta package. In this way, phenomenological studies using an
effective field theory framework can be straightforwardly performed.
