Abstract: The Comprehensive Research with Echelles on the Most interesting Eclipsing binaries (CRÉME) projects was aimed to collect high-resolutions spectra of about 380 detached eclipsing binaries (DEBs), which mostly do not have literature RV data. From this vast observational material we were able to estimate masses of components of 325 double-lined system. Since the launch of the TESS mission we have been collecting 2-min cadence photometry for the CRÉME targets through successful GI proposals. As by Sector 85, we obtained data for >330 of them. We are thus now in the process of comprehensively analysing our targets. This paper presents the recent status of the CRÉME project and its space photometry counterpart, and describes several sub-projects within CRÉME that focus on specific classes of targets.
