**simtools** is a modular toolkit for managing simulation model parameters, configuring, running, and validating simulation productions for arrays of imaging atmospheric Cherenkov telescopes.

**Documentation**: [simtools documentation](https://gammasim.github.io/simtools/)

**simtools** is part of the [SimPipe](http://cta-computing.gitlab-pages.cta-observatory.org/dpps/simpipe/simpipe/latest/) pipeline of the [Cherenkov Telescope Array Observatory (CTAO)](https://www.cta-observatory.org/).

**Authors**: see the [CITATION.cff](https://github.com/gammasim/simtools/blob/main/CITATION.cff) file.

> **Note**
> simtools is under active development.

## Features

- Simulation model libraries and management
- Database interfaces for simulation model parameters (see [CTAO Simulation models](https://gitlab.cta-observatory.org/cta-science/simulations/simulation-model/simulation-models))
- Tools for preparing, configuring, running, and validating simulation productions
- Applications for deriving and validating model parameters (see CTAO [Model setting and validation workflows](https://gitlab.cta-observatory.org/cta-science/simulations/simulation-model/simulation-model-parameter-setting))
- Standardized interfaces and outputs independent of the simulation software (e.g., [CORSIKA](https://www.iap.kit.edu/corsika/) air shower simulations and [sim_telarray](https://www.mpi-hd.mpg.de/hfm/~bernlohr/sim_telarray/) telescope simulations)
- I/O and reporting tools for the simulation model and production database
