-
-## Updating changedetection.io
-
-### Docker
-```
-docker pull dgtlmoon/changedetection.io
-docker kill $(docker ps -a -f name=changedetection.io -q)
-docker rm $(docker ps -a -f name=changedetection.io -q)
 docker run -d --restart always -p "127.0.0.1:5000:5000" -v datastore-volume:/datastore --name changedetection.io dgtlmoon/changedetection.io
-```
-
-### docker-compose
-
-```bash
-docker-compose pull && docker-compose up -d
-```
-
-See the wiki for more information https://github.com/dgtlmoon/changedetection.io/wiki
-
-
-## Filters
-
-XPath, JSONPath, jq, and CSS support comes baked in! You can be as specific as you need, use XPath exported from various XPath element query creation tools. 
-(We support LXML `re:test`, `re:math` and `re:replace`.)
-
-## Notifications
-
-ChangeDetection.io supports a massive amount of notifications (including email, office365, custom APIs, etc) when a web-page has a change detected thanks to the <a href="https://github.com/caronc/apprise">apprise</a> library.
-Simply set one or more notification URL's in the _[edit]_ tab of that watch.
-
-Just some examples
-
-    discord://webhook_id/webhook_token
-    flock://app_token/g:channel_id
-    gitter://token/room
-    gchat://workspace/key/token
-    msteams://TokenA/TokenB/TokenC/
-    o365://TenantID:AccountEmail/ClientID/ClientSecret/TargetEmail
-    rocket://user:password@hostname/#Channel
-    mailto://user:pass@example.com?to=receivingAddress@example.com
-    json://someserver.com/custom-api
-    syslog://
- 
-<a href="https://github.com/caronc/apprise#popular-notification-services">And everything else in this list!</a>
-
-<img src="https://raw.githubusercontent.com/dgtlmoon/changedetection.io/master/docs/screenshot-notifications.png" style="max-width:100%;" alt="Self-hosted web page change monitoring notifications"  title="Self-hosted web page change monitoring notifications"  />
-
-Now you can also customise your notification content and use <a target="_new" href="https://jinja.palletsprojects.com/en/3.0.x/templates/">Jinja2 templating</a> for their title and body!
-
-## JSON API Monitoring
-
-Detect changes and monitor data in JSON API's by using either JSONPath or jq to filter, parse, and restructure JSON as needed.
-
-![image](https://raw.githubusercontent.com/dgtlmoon/changedetection.io/master/docs/json-filter-field-example.png)
-
-This will re-parse the JSON and apply formatting to the text, making it super easy to monitor and detect changes in JSON API results
-
-![image](https://raw.githubusercontent.com/dgtlmoon/changedetection.io/master/docs/json-diff-example.png)
-
-### 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 specifc 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
-
-### Parse JSON embedded in HTML!
-
-When you enable a `json:` or `jq:` filter, you can even automatically extract and parse embedded JSON inside a HTML page! Amazingly handy for sites that build content based on JSON, such as many e-commerce websites. 
-
-```
-<html>
-...
-<script type="application/ld+json">
-
-{
-   "@context":"http://schema.org/",
-   "@type":"Product",
-   "offers":{
-      "@type":"Offer",
-      "availability":"http://schema.org/InStock",
-      "price":"3949.99",
-      "priceCurrency":"USD",
-      "url":"https://www.newegg.com/p/3D5-000D-001T1"
-   },
-   "description":"Cobratype King Cobra Hero Desktop Gaming PC",
-   "name":"Cobratype King Cobra Hero Desktop Gaming PC",
-   "sku":"3D5-000D-001T1",
-   "itemCondition":"NewCondition"
-}
-</script>
 ```  
 
-`json:$..price` or `jq:..price` would give `3949.99`, or you can extract the whole structure (use a JSONpath test website to validate with)
+Now visit http://127.0.0.1:5000 , You should now be able to access the UI.
 
-The application also supports notifying you that it can follow this information automatically
+#### Updating to latest version
 
+Highly recommended :)
 
-## Proxy Configuration
+```bash
+docker pull dgtlmoon/changedetection.io
+docker kill $(docker ps -a|grep changedetection.io|awk '{print $1}')
+docker rm $(docker ps -a|grep changedetection.io|awk '{print $1}')
+docker run -d --restart always -p "127.0.0.1:5000:5000" -v datastore-volume:/datastore --name changedetection.io dgtlmoon/changedetection.io
+```
+  
+### Screenshots
 
-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)
+Examining differences in content.
 
-## Raspberry Pi support?
+![Self-hosted web page change monitoring context difference screenshot](screenshot-diff.png?raw=true "Self-hosted web page change monitoring context difference screenshot")
 
-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)
+### Future plans
 
-## API Support
+- Greater configuration of check interval times, page request headers.
+- ~~General options for timeout, default headers~~
+- On change detection, callout to another API (handy for notices/issue trackers)
+- ~~Explore the differences that were detected~~ 
+- Add more options to explore versions of differences
+- Use a graphic/rendered page difference instead of text (see the experimental `selenium-screenshot-diff` branch)
 
-Supports managing the website watch list [via our API](https://changedetection.io/docs/api_v1/index.html)
-

-# 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)

-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
