+          Use this query parameter to filter for the packages thats suits your use case.
+          It can be used by passing in either package names or package ids. 
+          To query for multiple packages you can pass in comma separated values.
+          For example:
+
+          ```
+
+          package_query=17ea97c0-d350-45ce-9f36-ebb66694196c,558664cd-fece-47f5-a9ca-f30974cf96a5,...
+
+          ```
+
+          Or if you prefer using package names, you can also pass in 
+
+          ```
+
+          package_query=package_name_1,package_name_2...
