-**Get monitoring now! super simple, one command!**
-
-```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.

+## 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

+## Filters
+XPath, JSONPath and CSS support comes baked in! You can be as specific as you need, use XPath exported from various XPath element query creation tools.
+
+## 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.

-### Proxy
+Now you can also customise your notification content!
 
-A proxy for ChangeDectection.io can be configured by setting environment the 
-`HTTP_PROXY`, `HTTPS_PROXY` variables, examples are also in the `docker-compose.yml`
+## JSON API Monitoring
 
-`NO_PROXY` exclude list can be specified by following `"localhost,192.168.0.0/24"`
+Detect changes and monitor data in JSON API's by using the built-in JSONPath selectors as a filter / selector.
 
-as `docker run` with `-e`

+
+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

+
+### 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. 
 
 ```
-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

+  {"@context":"http://schema.org","@type":"Product","name":"Nan Optipro Stage 1 Baby Formula  800g","price": 23.50 }
+</script>
+```  
 
-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>.
+`json:$.price` would give `23.50`, or you can extract the whole structure
 
-For more information see https://docs.python-requests.org/en/master/user/advanced/#proxies
+## Proxy configuration
 
-This proxy support also extends to the notifications https://github.com/caronc/apprise/issues/387#issuecomment-841718867

-- Wont work with Cloudfare type "Please turn on javascript" protected pages
-- You can use the 'headers' section to monitor password protected web page changes
+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)
