+## Proxy Configuration
+
+See the wiki https://github.com/dgtlmoon/changedetection.io/wiki/Proxy-configuration , we also support using [BrightData proxy services where possible]( https://github.com/dgtlmoon/changedetection.io/wiki/Proxy-configuration#brightdata-proxy-support)
 
 ## Raspberry Pi support?
 
 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)

+# 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)
