Pcbnew window: Press esc key Hover cursor over GND label	Similarly connect all the other nodes except the Ground nodes. Press Esc key to exit the Place Track tool. Ground nodes are denoted by GND designation.
	Let us place a ground plane to connect all the ground nodes.
Pcbnew window: Click on Add filled zones.	Click on Add filled zones button located at the right side of the Pcbnew window.
Pcbnew window: Click once, slightly above the top-left corner of the board outline.	Click once, slightly above the top-left corner of the board outline.
Copper Zone Properties window: Click on B.Cu under Layer column Click on GND under Net column	Let us place the ground plane on Bottom Copper layer. To do so, click on B.Cu under Layer column. Click on GND under Net column.
Click on OK	Click on OK button at the bottom right corner of the Copper Zone Properties window.
Pcbnew window: Drag the cursor towards right, horizontally Click once slightly above top-right vertex of the outline.	Drag the cursor with the pencil icon horizontally towards the right.  Click once, slightly above the top-right vertex of the outline.
Pcbnew window: Move the cursor vertically towards the bottom-left vertex of the board >> Click once on the editor after crossing the bottom-left vertex.	Let us move this cursor vertically, towards the bottom-right vertex of the board. Click once slightly below bottom-right vertex.
Pcbnew window: Press esc key Hover cursor over board outline >> Hover cursor over ground plane outline.	Similarly, we will draw a rectangular ground plane outline around board outline. Press esc key to exit the ground plane outline tool Please do not confuse board outline with ground plane outline.
Pcbnew window: Hover cursor over ground plane outline  >> Hover cursor over ground plane outline and board outline.	I have completed the ground plane outline. Note that the ground plane outline should lie outside the board outline.
Pcbnew window : Right-click inside the board outline. Click on Fill or Refill all zones Hover cursor over ground plane	Right-click inside the board outline. Click on Fill or Refill all zones button from the menu. We have added a ground plane to the board.
Press esc key	Press Esc key to exit the Add filled zones tool.
	Let us now perform Design Rule Check i.e DRC, for the layout we created.  It checks whether the design created is compliant with the Design Rules set earlier.
Pcbnew window: Click on Perform design rules check	Click on Perform Design Rules check present at the top of the Pcbnew toolbar.
DRC Control window: Click on Start DRC Hover mouse over Error Messages:	Click on Start DRC.  This checks if any design element violates the design parameters set earlier. If there are any design errors, they will be displayed in Error Messages window. In my case, there are no errors.
DRC Control window: Click OK	Click OK button at the bottom right corner to exit the DRC Control window.
	Now let us see how to add text on our board.
Pcbnew window: Click on F.Silks from the right toolbar Click on Place from the top toolbar and select Text from the dropdown menu  Click once on Pcbnew window	Let us click on F.Silks layer to place text on the Front Silk Layer. Click on Place button from top toolbar and select Text option from the dropdown menu. Click once on the Pcbnew window.
Text Properties window:  Type 7805VoltageRegulator in the Text window. Click on OK	I will type 7805VoltageRegulator in the Text window. click on OK button at the bottom right corner of the Text Properties window.
Pcbnew window: Click once at the bottom right corner of layout screen. Press F2 or use scroll keys to zoom out and hover cursor over the text.	The typed text will be tied to the cursor. Drag cursor to bottom right corner of the layout screen and click once. We can see the text is placed in light blue color.
