+# GOAL 2: Printing the Clock
+
+## Notes
+
+* Note main.go file contains the solution of the previous step.
+* "solution" folder contains the solution for this step.
+
+## Challenge Steps
+
+1. Get the current time
+
+2. Get the current hour, minute and second from the current time
+
+3. Create the clock array by getting the digits from the digits array
+
+4. Print the clock by using the clock array
+
+5. Create a separator array (it's also a placeholder type)
+
+6. Add the separators into the correct positions of the clock array
