In this talk we present an update on the results of theDouble Chooz detector. This experiment searches for themixing angle, $\theta_{13}$, in the three-neutrino mixing matrix via the disappearance of $\bar \nu_e$ produced by the dual 4.27 GWth Chooz B Reactors. We will show an update oscillation fit results using both the rate and the shape of the anti-neutrino energy spectrum. In the oscillation analysis we will include data with neutron capture on Gadolinium and Hydrogen and we will present the independent Reactor Rate Modulation (RRM) measurement of $\theta_{13}$ and the agreement with the rate+shape results. This is an important step in our multi-years program to establish the value of $\theta_{13}$. We will also give an update on the construction of the Double Chooz Near Detector and projections of Double Chooz's future experimental sensitivity to measure $\sin^22\theta_{13}$-driven oscillations.
