+- You can move gates by dragging their buttons (not the plus ones)
+- To create connections, click on the + buttons, left is the input, right is the output
+- A node has to have 2 inputs(Except the OUTPUT node), but only 1 output
+- You have to connect the nodes in a way to meet the required result

+Logical Gates explanation:
+- AND: Returns 1 if both inputs are 1, otherwise 0
+- OR: Returns 1 if any inputs are 1, otherwise 0
+- NAND: Returns 1 if any inputs are 0, otherwise 0
+- NOR: Returns 1 if both inputs are 0, otherwise 0
+- XOR: Returns 1 if inputs are different, otherwise 0
+- XNOR: Returns 1 if inputs are the same, otherwise 0
