The flows of gas into galaxies, and from them back to their environments, have assumed increasing importance at the frontier of galaxy formation studies. The purpose of this Symposium was to bring together the multi-wavelength communities that study the gas flows into, within, and out of galaxies, and which drive their evolution. The scientific sessions of the meeting addressed the following key questions:

• How do baryons cycle in and out of galaxies?
• What are the flows of matter, energy, and metals in the circumgalactic medium?
• What controls the matter, energy, and chemical cycles within galaxies?
• How do gas flows influence galaxy evolution?

These and other questions were addressed by a set of invited talks. We also invited contributions in the form of talks and posters.
