 # wbm-alert
 This script creates (text) snapshots for a given list of websites. A request to each website is made every 30 seconds. If the contents of the website have changed, a notification sound is played.
 
-## Limitations
-The snapshot only considers the textual contents of a website. If images, links, or HTML attributes change, the alarm may not sound. In more technical terms: `<a href="https://google.com">Link</a>` is sanitized to `Link`. All whitespace (including tabs and line breaks) is also removed.
-
-## What is it good for?
-I used it to monitor real estate websites to be notified of new listings. I was particularly interested in Berlin's state-owned Wohnungsbaugesellschaft Berlin-Mitte (WBM), hence the name `wbm-alert`.
