 # wedding-rsvp-rs
 
-This [Rust](https://www.rust-lang.org/) and [Rocket.rs](https://rocket.rs) based, fully responsive website is a simple contact form to RSVP to a wedding. It was meant to be simple to use, since a lot of non-tech-savvy people will usually attend a wedding as well ;-). Therefore, it is completely email based and does not include any CAPTCHA.

 ## Features
+
 * **KISS**: Not too many features and fields, no databases, no CAPTCHA.
-* **Completely email based**: The guest will receive a confirmation with additional information on top of the invite he got. Attached to this email, an ICS file enables the user to directly add the wedding into his calendar.
+* **Completely (HTML) email based**: The guest will receive a confirmation with additional information on top of the invite he got. Attached to this email, an ICS file enables the user to directly add the wedding into his calendar.
 * **Configurable, multi-language strings**: All language strings can be defined in `config.hjson`. Since this website assumes that a different FQDN is used for every language, the mapping between TLDs and languages must be configured in `config.hjson` as well. 
 * **IP based spam protection**: As mentioned before, this website does not include CAPTCHA to ease usability. There is, however, a small protection so that one IP can only send an email every X seconds. Here, X can be configured in `config.hjson`.
