+## Self-hosted open source change monitoring of web pages.
+
+_Know when web pages change! Stay ontop of new information!_ 
+
+Live your data-life *pro-actively* instead of *re-actively*, do not rely on manipulative social media for consuming important information.

+
+#### Example use cases
+
+Know when ...
+
+- Government department updates (changes are often only on their websites)
+- Local government news (changes are often only on their websites)
+- New software releases, security advisories when you're not on their mailing list.
+- Festivals with changes
+- Realestate listing changes
+- COVID related news from government websites
+- Detect and monitor changes in JSON API responses 
+- API monitoring and alerting
+
+**Get monitoring now!**
+
+```bash
+$ pip3 install changedetection.io   
+```
+
+Specify a target for the *datastore path* with `-d` (required) and a *listening port* with `-p` (defaults to `5000`)
+
+```bash
+$ changedetection.io -d /path/to/empty/data/dir -p 5000
+```
+
+
+Then visit http://127.0.0.1:5000 , You should now be able to access the UI.

 **Get monitoring now! super simple, one command!**
 
+Run the python code on your own machine by cloning this repository, or with <a href="https://docs.docker.com/get-docker/">docker</a> and/or <a href="https://www.digitalocean.com/community/tutorial_collections/how-to-install-docker-compose">docker-compose</a>
+
+**Docker**
+
+With Docker composer, just clone this repository and
 ```bash
-docker run -d --restart always -p "127.0.0.1:5000:5000" -v datastore-volume:/datastore --name changedetection.io dgtlmoon/changedetection.io
-```  
-
-Now visit http://127.0.0.1:5000 , You should now be able to access the UI.
-
-#### Updating to latest version
-
-Highly recommended :)
-
-```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-compose up -d
 ```
-  
+Docker standalone
+```bash

+```bash
+$ pip3 install changedetection.io
+$ changedetection.io -d /path/to/empty/data/dir -p 5000
+```
+
+Then visit http://127.0.0.1:5000 , You should now be able to access the UI.
+

 ### Screenshots
 
 Examining differences in content.

-### Future plans
-
-- 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)

+
+### 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">And everything else in this list!</a>
+
+<img src="https://raw.githubusercontent.com/dgtlmoon/changedetection.io/master/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!
+
+### JSON API Monitoring
+
+Detect changes and monitor data in JSON API's by using the built-in JSONPath selectors as a filter / selector.
+
+![image](https://user-images.githubusercontent.com/275001/125165842-0ce01980-e1dc-11eb-9e73-d8137dd162dc.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://user-images.githubusercontent.com/275001/125165995-d9ea5580-e1dc-11eb-8030-f0deced2661a.png)
+
+#### Parse JSON embedded in HTML!
+
+When you enable a `json:` 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","name":"Nan Optipro Stage 1 Baby Formula  800g","price": 23.50 }
+</script>
+```  
+
+`json:$.price` would give `23.50`, or you can extract the whole structure
+
+### Proxy
+
+A proxy for ChangeDetection.io can be configured by setting environment the 
+`HTTP_PROXY`, `HTTPS_PROXY` variables, examples are also in the `docker-compose.yml`
+
+`NO_PROXY` exclude list can be specified by following `"localhost,192.168.0.0/24"`
+
+as `docker run` with `-e`
+
+```
+docker run -d --restart always -e HTTPS_PROXY="socks5h://10.10.1.10:1080" -p "127.0.0.1:5000:5000" -v datastore-volume:/datastore --name changedetection.io dgtlmoon/changedetection.io
+```
+
+With `docker-compose`, see the `Proxy support example` in <a href="https://github.com/dgtlmoon/changedetection.io/blob/master/docker-compose.yml">docker-compose.yml</a>.
+
+For more information see https://docs.python-requests.org/en/master/user/advanced/#proxies
+
+This proxy support also extends to the notifications https://github.com/caronc/apprise/issues/387#issuecomment-841718867
+
+
+### RaspberriPi support?
+
+RaspberriPi and linux/arm/v6 linux/arm/v7 arm64 devices are supported! 
+
+
+### Support us
+
+Do you use changedetection.io to make money? does it save you time or money? Does it make your life easier? less stressful? Remember, we write this software when we should be doing actual paid work, we have to buy food and pay rent just like you.
