Geppetto is a web based platform to build neuroscience applications that let the user  **explore, visualize and simulate neuroscience data and models** such as a **cell** or even a **whole brain**.

A demo application using latest release of Geppetto is available [here](https://live.geppetto.org) while the binaries are available to
[download here](https://github.com/openworm/org.geppetto/releases/).
The documentation is split into two main sections: a guide to help you learn how to use Geppetto based applications and the developers documentation, to learn how to build applications based on Geppetto and how to contribute to it.

If you have any problems you can write in the Slack Geppetto Channel (email info@geppetto.org to get an invitation), we'll be happy to help you!
