-## Self-hosted change monitoring of web pages.
+![changedetection.io](https://github.com/dgtlmoon/changedetection.io/actions/workflows/test-only.yml/badge.svg?branch=master)
 
-_Why?_ Many years ago I had used a couple of web site change detection/monitoring services, 
-but they got bought up by larger media companies, after this, whenI logged in they
-wanted _even more_ private data about me.
+## Self-Hosted, Open Source, Change Monitoring of Web Pages
 
-All I simply wanted todo was to know which pages were changing and when (and maybe see
-some basic information about what those changes were)
+_Know when web pages change! Stay ontop of new information!_ 
 
-![Alt text](screenshot.png?raw=true "Screenshot")
+Live your data-life *pro-actively* instead of *re-actively*, do not rely on manipulative social media for consuming important information.

+
+Please :star: star :star: this project and help it grow! https://github.com/dgtlmoon/changedetection.io/
+
+
+## Installation
+
+### Docker
+
+With Docker composer, just clone this repository and..
+```bash
+$ docker-compose up -d
+```
+Docker standalone
+```bash
+$ docker run -d --restart always -p "127.0.0.1:5000:5000" -v datastore-volume:/datastore --name changedetection.io dgtlmoon/changedetection.io
+```
+
+### Python Pip
+
+Check out our pypi page https://pypi.org/project/changedetection.io/
+
+```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.
+
+_Now with per-site configurable support for using a fast built in HTTP fetcher or use a Chrome based fetcher for monitoring of JavaScript websites!_
+
+## Updating changedetection.io
+
+### Docker
+```
+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
+```
+
+### docker-compose
+
+```bash
+docker-compose pull && docker-compose up -d
+```
+
+### 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/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. 
 
 ```
-$ git clone https://github.com/dgtlmoon/changedetection.io.git
-$ cd changedetection.io
-$ docker-compose up -d
+<html>
+...
+<script type="application/ld+json">
+  {"@context":"http://schema.org","@type":"Product","name":"Nan Optipro Stage 1 Baby Formula  800g","price": 23.50 }
+</script>
 ```  
 
-Now visit http://127.0.0.1:5000 , The interface will now expose the UI, you can change this in the `docker-compose.yml`
+`json:$.price` would give `23.50`, or you can extract the whole structure
 
-### Future plans
+### Proxy
 
-- 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.
-- Use a graphic/rendered page difference instead of text (see the experimental `selenium-screenshot-diff` branch)
+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! 
+
+### Windows native support?
+
+Sorry not yet :( https://github.com/dgtlmoon/changedetection.io/labels/windows
+
+### 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.
+
+Please support us, even small amounts help a LOT.
