-#### Key Features
-
-- Lots of trigger filters, such as "Trigger on text", "Remove text by selector", "Ignore text", "Extract text", also using regular-expressions!
-- Target elements with xPath and CSS Selectors, Easily monitor complex JSON with JsonPath rules
-- Switch between fast non-JS and Chrome JS based "fetchers"
-- Easily specify how often a site should be checked
-- Execute JS before extracting text (Good for logging in, see examples in the UI!)
-- Override Request Headers, Specify `POST` or `GET` and other methods
-- Use the "Visual Selector" to help target specific elements
