First things first, we have to create a eric6 project. In order to accomplish that, we simply hit the 'Project' menu item and then 'New...'.
A 'new project' dialog pops up, and we will set some project properties.
The most important are the path where the project will be created, programming language, project type and main script.
For these properties, we set the project name as MiniBrowser, programming language as Python3 (you could use Python2 if you wanted), PyQt5 GUI, and we provide the name for the main script's file: minibrowser.py
We hit the 'Ok' button and a new dialog appears asking if we want to add files to project. We click no (as there are no actual files to be included).
Another dialog pops up asking which version control system is to be used. We select 'none' and hit 'Ok'.
