-- 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(1.0) and CSS Selectors, Easily monitor complex JSON with JSONPath or jq
-- Switch between fast non-JS and Chrome JS based "fetchers"
-- Track changes in PDF files (Monitor text changed in the PDF, Also monitor PDF filesize and checksums)
-- 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
-- Configurable [proxy per watch](https://github.com/dgtlmoon/changedetection.io/wiki/Proxy-configuration)
-- Send a screenshot with the notification when a change is detected in the web page

-### JSONPath or jq?
-
-For more complex parsing, filtering, and modifying of JSON data, jq is recommended due to the built-in operators and functions. Refer to the [documentation](https://stedolan.github.io/jq/manual/) for more specific information on jq.
-
-One big advantage of `jq` is that you can use logic in your JSON filter, such as filters to only show items that have a value greater than/less than etc.

-See the wiki https://github.com/dgtlmoon/changedetection.io/wiki/JSON-Selector-Filter-help for more information and examples

 Raspberry Pi and linux/arm/v6 linux/arm/v7 arm64 devices are supported! See the wiki for [details](https://github.com/dgtlmoon/changedetection.io/wiki/Fetching-pages-with-WebDriver)
 
-## Import support
-
-Easily [import your list of websites to watch for changes in Excel .xslx file format](https://changedetection.io/tutorial/how-import-your-website-change-detection-lists-excel), or paste in lists of website URLs as plaintext. 
-
-Excel import is recommended - that way you can better organise tags/groups of websites and other features.

-# HORRIBLE HACK BUT WORKS :-) PR anyone?
-#
-# Why?
-# `browsersteps_playwright_browser_interface.chromium.connect_over_cdp()` will only run once without async()
-# - this flask app is not async()
-# - browserless has a single timeout/keepalive which applies to the session made at .connect_over_cdp()
-#
-# So it means that we must unfortunately for now just keep a single timer since .connect_over_cdp() was run
-# and know when that reaches timeout/keepalive :( when that time is up, restart the connection and tell the user
-# that their time is up, insert another coin. (reload)
-#
-# Bigger picture
-# - It's horrible that we have this click+wait deal, some nice socket.io solution using something similar
-# to what the browserless debug UI already gives us would be smarter..
-#
-# OR
-# - Some API call that should be hacked into browserless or playwright that we can "/api/bump-keepalive/{session_id}/60"
-# So we can tell it that we need more time (run this on each action)
-#
-# OR
-# - use multiprocessing to bump this over to its own process and add some transport layer (queue/pipes)

-## How it works
-
-Watch has a list() of tag UUID's, which relate to a config under application.settings.tags
-
-The 'tag' is actually a watch, because they basically will eventually share 90% of the same config.
-
-So a tag is like an abstract of a watch

-The concept here is to be able to switch between different domain specific problems to solve.
-
-- `text_json_diff` The traditional text and JSON comparison handler
-- `restock_diff` Only cares about detecting if a product looks like it has some text that suggests that it's out of stock, otherwise assumes that it's in stock.
-
-Some suggestions for the future
-
-- `graphical` 
-- `restock_and_price` - extract price AND stock text
