The Double Chooz experiment has been at the forefront of accurately measuring the third neutrino mixing angle $\theta_{13}$. The experiment involves two identical liquid scintillator detectors at 400 m and 1 km baselines from the two nuclear reactors in Chooz, France. To detect the neutrinos, the experiment uses the "Total Neutron Capture" technique to measure the inverse beta decay (IBD) signature, which includes prompt positron annihilation and a delayed neutron capture signal on all possible isotopes available in the detector. The experiment's double detector setup, carefully considering all neutrino rates, energy spectral shapes, and inclusive backgrounds control model, allows for accurate measurement of $\theta_{13}$ and a precise characterization of the reactor flux. The latest results from the Double Chooz measurement and advances are presented in this proceeding.
