 However, hook defined like that could pose a security threat to your system, because anyone who knows your endpoint, can send a request and execute your command. To prevent that, you can use the `"trigger-rule"` property for your hook, to specify the exact circumstances under which the hook would be triggered. For example, you can use them to add a secret that you must supply as a parameter in order to successfully trigger the hook. Please check out the [Hook rules page](https://github.com/adnanh/webhook/wiki/Hook-Rules) for detailed list of available rules and their  usage.
 
+# Using HTTPS
+[webhook](https://github.com/adnanh/webhook/) by default serves hooks using http. If you want [webhook](https://github.com/adnanh/webhook/) to serve secure content using https, you can use the `-secure` flag while starting [webhook](https://github.com/adnanh/webhook/). Files containing a certificate and matching private key for the server must be provided using the `-cert /path/to/cert.pem` and `-key /path/to/key.pem` flags. If the certificate is signed by a certificate authority, the cert file should be the concatenation of the server's certificate followed by the CA's certificate.

 # Examples
 Check out [Hook examples page](https://github.com/adnanh/webhook/wiki/Hook-Examples) for more complex examples of hooks.
