+Description
+</summary>
+Hey, I can use Web-Retriever plugin to help you summarize small parts of a WEB page or PDF content.
+
+With this plugin I can process WEB pages that have static HTML content, so web
+sites like medium, Wiki etc. should just fine work.
+
+This is how you can make me to use it:
+
+```text
+Please summarize this web page for me: https://en.wikipedia.org/wiki/Lorem_ipsuma
+```
+
+Or if you do not have URL, you could try like:
+
+```text
+What is the capital of (France)?
+```
