**Set up Discourse on a cloud server in under 30 minutes** with zero knowledge of Ruby, Rails or Linux shell using our [Discourse Docker image][dd]. We prefer [Digital Ocean][do], although these steps may work on other cloud providers that also support Docker. Let's begin!
Use the URL of your new site as the Droplet hostname, e.g. `discourse.example.com`. Discourse requires a minimum of **1 GB RAM** for small communities; we recommend 2 GB RAM for medium communities.
You will receive a mail from Digital Ocean with the root password to your Droplet. (However, if you know [how to use SSH keys](https://www.google.com/search?q=digitalocean+ssh+keys), you may not need a password to log in.)
You will be asked for permission to connect, type `yes`, then enter the root password from the email Digital Ocean sent you when the Droplet was set up. You may be prompted to change the root password, too.
- If you're using the minimum 1 GB install, you *must* [set up a swap file](https://meta.discourse.org/t/create-a-swapfile-for-your-linux-server/13880).
- Set `DISCOURSE_HOSTNAME` to `discourse.example.com`, this means you want your Discourse available at `http://discourse.example.com/`. You'll need to update the DNS A record for this domain with the IP address of your server.
- Place your mail credentials in `DISCOURSE_SMTP_ADDRESS`, `DISCOURSE_SMTP_PORT`, `DISCOURSE_SMTP_USER_NAME`, `DISCOURSE_SMTP_PASSWORD`. Be sure you remove the comment `#` character and space from the front of these lines as necessary.
**Email is CRITICAL for account creation and notifications in Discourse. If you do not properly configure email before bootstrapping YOU WILL HAVE A BROKEN SITE!**
- No existing mail server, or you don't know what it is? No problem, create a free account on [**Mandrill**][man] (or [Mailgun][gun], or [Mailjet][jet]), and use the credentials provided in the dashboard.
- For proper email deliverability, you must set the [SPF and DKIM records](http://help.mandrill.com/entries/21751322-What-are-SPF-and-DKIM-and-do-I-need-to-set-them-up-) in your DNS. In Mandrill, that's under Sending Domains, View DKIM/SPF setup instructions.
It should be accessible via the domain name `discourse.example.com` you entered earlier, provided you configured DNS. If not, you can also visit the server IP directly, e.g. `http://192.168.1.1`.
There is a reminder at the top about `DISCOURSE_DEVELOPER_EMAILS`; register a new account via one of those email addresses, and your account will automatically be made an Admin.
(If you *don't* get any email from your install, and are unable to register a new admin account, please see our [Email Troubleshooting checklist](https://meta.discourse.org/t/troubleshooting-email-on-a-new-discourse-install/16326).)
You should see Staff topics and the [Admin Quick Start Guide](https://github.com/discourse/discourse/blob/master/docs/ADMIN-QUICK-START-GUIDE.md). It contains the next steps for further configuring and customizing your Discourse install.
