# Solidity Brand Policy and Logo Guidelines

## The Solidity Brand

The Solidity programming language is an open-source, community project governed by a core team. The core team is sponsored by the Ethereum Foundation.

This document aims to provide information about how to best use the Solidity brand name and logo.

We encourage you to read this document carefully when wanting to use the brand name or the logo. Your cooperation is highly appreciated!

## Solidity Brand Name

"Solidity" should be used to refer to the Solidity programming language solely.

Please don't use "Solidity":

* To refer to any other programming language.
* In a way that is misleading or may imply association of unrelated modules, tools, documentation, or other resources with the Solidity programming language.
* In ways that confuse the community as to whether the Solidity programming language is open-source and free to use.

## Solidity Logo Guidelines

You can find the official Solidity logo SVG [here](https://github.com/ethereum/solidity/blob/develop/docs/logo.svg). 

Please do not:

* Change the ratio of the logo (don't stretch it or cut it).
* Change the colors of the logo, unless it is absolutely necessary.
