# Overview

If you believe you have high quality bioactivity data that others would benefit from viewing in ChEMBL, then please:

* Sign up to the [deposition mailing list](https://listserver.ebi.ac.uk/mailman/listinfo/chembl-depositors).
* contact us by email: at <data-deposition-chembl@ebi.ac.uk>.

This document provides a basic introduction as to how bioactivity data should be formatted in order to be loaded into ChEMBL. Many aspects of this are best explained by reference to examples (see [Example Load Dataset](https://chembl.gitbook.io/chembl-data-deposition-guide/example)).

### Deposition Overview

There is a downloadable guide to the basics of deposition [here](https://docs.google.com/document/d/1uiT8mDCvMlOkw-zk4F2CbBMPYJCg5np0Zasnfb6Bzbo/edit), designed to be easy to share with your collaborators.

#### Video Guide

We also have a short [video guide](https://embl-ebi.cloud.panopto.eu/Panopto/Pages/Viewer.aspx?id=4b4d09da-ce29-4b72-b649-b0750115cad7) to producing these files, using an example dataset.

#### Checklist

There is a checklist for the deposition process [here](https://docs.google.com/document/d/1MGuo3MCk-BP7wgBffOn1bRZ7AdSrrHUDIvFaiOr0oZI/edit?usp=sharing), which we recommend working through once you have created files to send to us.&#x20;
