The Atacama Large Millimeter/Submillimeter Array (ALMA) is a major new interferometer in the northern Atacama desert. ALMA is a partnership between North America, Europe, and East Asia in cooperation with the Republic of Chile. We are currently in the first year of science observations using a partial array. This phase is called ALMA Early Science Cycle 0, and the capabilities are defined to be: an array of at least sixteen 12 m antennas, receiver bands centered at wavelengths of about 3, 1.3, 0.8 and 0.45 mm, baselines from 18 to 400 m, single field imaging and mosaics of up to 50 pointings, and a set of correlator modes that will allow both continuum and spectral line observations. I will present the telescope and its instrumentation and I will talk about the challenges we face operating telescope of this scale at Chajnantor. I will also present statistics from the proposals and the observations and finally I will show some science highlights from the first year of ALMA.
