-Currently the easiest and fastest way to set up the bot is using Heroku. If you choose to install the bot using Heroku, you will not need to download anything. Read the **[installation guide](https://github.com/kyb3r/modmail/wiki/Installation)**. If you ran into any problems, join our [discord server](https://discord.gg/etJNHCQ) for help and support. Even if you don't have any issues, you should come and check out our awesome Discord community! :wink:

-## What is Heroku?
-
-Heroku is a container based cloud platform that currently offers a free plan to host web apps. However, these apps have an ephemeral file system and thus cannot store any data on site. We have made Modmail be accessible to anyone while still being feature-rich; it's a community run project that lets anyone get it up and running 24/7 for free. So how does our bot store data? Configs and logs are stored in a [centralized web service](https://modmail.tk) hosted by us. This enables you to get started easily and fast. However, you do also have the option to self-host your data, check the installation guide for more info.
