# Overview

Loading data to ChEMBL is largely by invitation. However, if you believe you have high quality bioactivity data that others would benefit from viewing in ChEMBL, then please contact us by email: <chembl-help@ebi.ac.uk>.

This document provides a basic introduction 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](/chembl-data-deposition-guide/~/revisions/t4ziM1Dk3kUY0U850C3g/example.md)).

### 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;
