 ``teracy-dev`` is created to set up a universal development platform which has the same development
 workflow on Mac, Linux and Windows with good developer experience and productivity in mind. 
 
-We leverage Docker workflow for our software development and we use ``vagrant``, ``virtualbox``, and
-``chef`` to install and configure any necessary packages.
 
-By using this approach, we can work in a consistent development environment and workflow.
-We do not have to install tons of development stuff on the host machine **manually** to get started.
-
-.. note:: We are using the https://github.com/acme101 project to show the best practices from ``teracy-dev`` applied for organizations.
+`teracy-dev` is super minimal kernel with extension mechanism so that we can use/ develop many
+different extensions by our needs.
