 This is an API plugin for Azure libraries. Users should not install this directly
 
+## Configuration
+
+It is possible to configure some settings with Java System Properties, specified with `-Dproperty=value` in the command line.
+
+### Http Client
+
+* `io.jenkins.plugins.azuresdk.HttpClientRetriever.readTimeoutSeconds` - This sets the read timeout (in seconds) of the HTTP client used for Azure API requests.
+* `io.jenkins.plugins.azuresdk.HttpClientRetriever.responseTimeoutSeconds` - This sets the response timeout (in seconds) of the HTTP client used for Azure API requests.
+* `io.jenkins.plugins.azuresdk.HttpClientRetriever.writeTimeoutSeconds` - This sets the write timeout (in seconds) of the HTTP client used for Azure API requests.
