Let’s take a moment to go over the points of interest on this window. On the bottom- left side of the status bar at the bottom of the window, you see the directory that the KiCad project file is in will be displayed, or will be blank if no project is open. To the left, you can see the project directory structurefiles. We’ll go more into this later on, but for now know that the area will display all the important files and folders that are contained within the project, such as the board’s electrical schematics, PCB layout, and parts libraries. On the left bartoolbar, you have the usual buttons for things such as saving, loading, creating a new project, along with a few others.

Note that I mentioned a few other applications in the descriptions above, such as the Schematic Editor, Symbol Editor, and PCB Editor. “But wait, isn’t KiCad all I need to make cool boards?” you may ask. You see, KiCad is an Electronics Design Automation Suite, and its functionality is contained within several programs, most of which you will use going through in this tutorial.

Now that we have some understanding of the UI, let’s get started on building our board. First, we will need to create a new project. This can be done by going to File > New > New Project…, hitting the Ctrl+N hotkey, or simply just clicking on the 
Create new blank project icon on the toolbar. A file browser will open up, in which you can choose a location to create the KiCad project file. By default, a new folder with the project name will be created at the chosen location and the file itself will be within it.
Upon creation, you will notice that the project directory area has been updated and now contains a .kicad_pro file with a .kicad_pcb and .kicad_sch file within it. All These are all the files you will need to create a PCB. We're not ready to start quite yet though, as we are missing a few custom component symbols and footprints that we will need for our board. To remedy this, we will be downloading and importing a few KiCad libraries.
...
There are two types of libraries in KiCad. Those that have the .kicad_sym extension contain symbols for electrical schematics, while libraries that have the .pretty extension like ours contain component footprints and silkscreens to be used during the PCB design stage. These libraries in particular The libraries that we copied contain some silkscreen Waterloo Rocketry logos and a footprint for a connector that we will need.
Let’s get this library hooked up to our project so we can actually use it – as just moving it into the folder does nothing. Go back to KiCad and navigate to Preferences > Manage Footprint Libraries… You should be met with the Footprint Libraries window in which you can manage all your KiCad footprints. There are two tabs to this window: one for Global Libraries, footprint libraries that all your KiCad projects have access to, and Project Specific Libraries, libraries that can only be accessed by our current project. Switch to the Project Specific Libraries tab and click on the Add Existing Library to Table button. A file browser will open, choose the Tutorial_Footprints.pretty file that is in your project directory. If everything was done correctly then the library table should now look like what’s below:
