# DD4hep (Detector Description for High Energy Physics) [](https://travis-ci.com/AIDASoft/DD4hep) [](https://gitlab.cern.ch/CLICdp/DetectorSoftware/DD4hep/commits/master) [](https://scan.coverity.com/projects/DD4hep) [](https://zenodo.org/badge/latestdoi/60682190) DD4hep is a software framework for providing a complete solution for full detector description (geometry, materials, visualization, readout, alignment, calibration, etc.) for the full experiment life cycle (detector concept development, detector optimization, construction, operation). It offers a consistent description through a single source of detector information for simulation, reconstruction, analysis, etc. It distributed under the [LGPLv3 License](http://www.gnu.org/licenses/lgpl-3.0.en.html) [](https://www.gnu.org/licenses/lgpl-3.0.en.html) ## Pre-requisites and installation For information about how to install DD4hep see [this page](https://dd4hep.web.cern.ch/dd4hep/page/installation/) ## Documentation Use's Manuals can be found [here](https://dd4hep.web.cern.ch/dd4hep/page/users-manual/).
