# Contributing Guidelines

Please read this before contributing.

## Rules

- Be nice and respectful.
- English only.
- Be constructive.

## Quality over Quantity

We're trying to keep it simple and promote the best tools, not all of them. Maximum are three software choices, but it's possible to add more under "Worth Mentioning" headlines. ([example](https://www.privacytools.io/#im))

## Software Criteria

- Open Source
- Cross-platform
- Easy to use
- Privacy respecting

There can be exceptions if no software is available that meet the criteria.

## Images

- Provider logos should be exactly 200 x 70 ([example](https://www.privacytools.io/assets/img/provider/AirVPN.png))
- Tool logos should be exactly 120 x 120 ([example](https://www.privacytools.io/assets/img/tools/ChatSecure.png))
