## Creating a new SSL certificate monitor

1. Click "SSL certificates"
2. Click "Register new SSL certificate"
3. Enter the relevant details:
   1. Hostname: Just use the hostname, don't add the `https://`. For example: `cronly.app`. You can use subdomains here: `dev.cronly.app`.
   2. Port: If you don't know this, it is probably `443`.
   3. Project: Use this to categorize your certificates. This can be useful when you want to monitor certificates of your client, for example
4. Click "Register new certificate"

## How do SSL certificate monitors work?

Once you create an SSL certificate monitor, we will start monitoring it. When the status changes, we will give you a heads-up. There are three possible statuses:

* `notification`: Your certificate will expire within 30 days
* `alert`: Your certificate has expired and is no longer valid, or it has not expired, but is invalid
* `healthy`: Your certificate is valid for more than 30 days

If you want to see more information about your certificates, you can view this in your dashboard.
