# RESCU+ RESCU+ software is a powerful density functional theory program for materials of large systems, including bulk materials, surfaces, and nanowires. RESCU+ is a complete rewrite of our original RESCU software (Matlab code), with a focus on even greater performance. RESCU+ combines the efficiency of Fortran/C/C++ and an easy-to-use Python interface for defining applications and performing post analysis. nanotools is a Python user interface for RESCU+. It includes modules to describes atomic structures and modules to perform calculations (e.g. total energy, EOS, dielectric constant). - [Installation](./installation/installation) provides instructions on how to build and install RESCU+. - [Getting Started](./gettingstarted) walks you through a very simple calculation example for RESCU+. - [API Reference](./source/nanotools) provides detailed documentation for nanotools classes. - [Tutorials](./tutorials/tutorials) contains how-to's and tutorials for all calculation types and more. - [Contact](./contact) will tell you how to reach us. - [Release Notes](./releasenote_rescu) includes latest features, enhancements and bug fixes ```{toctree} --- hidden: --- Installation Getting Started API Reference Tutorials Contact Release Notes ```
