+## Running the demo server
+As the resolver reacts to http requests, we need to setup a local server to answer to our requests.
+
+~~~admonish tip
+This can be easily done by running:
+- <install/dist root folder>/httpResolver/demo/server_install.sh/.bat file to create the python virtual environment with the necessary packages
+- <install/dist root folder>/httpResolver/demo/server_launch.sh/.bat file to run the demo server
+~~~
+
+~~~admonish warning
+Please make sure that you have python installed at the system level and available on your "PATH" environment variable.
+Our install scripts use it to create a virtual environment that runs the http demo server.
