The purpose of design is to allow you to do design later, and it's primary goal is to reduce the cost of change.

Single Responsibility Principle: a class should have only a single responsibility
Open-Closed Principle: Software entities should be open for extension, but closed for modification (inherit instead of modifying existing classes).
Liskov Substitution: Objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program.
Interface Segregation: Many client-specific interfaces are better than one general-purpose interface.

	# Sometimes you need to move your existing git repository
	# to a new remote repository (/new remote origin).
	# Here are a simple and quick steps that does exactly this.

	# to move, and "new repo" the one you wish to move to.
	#
	### Step 1. Make sure you have a local copy of all "old repo"
	### branches and tags.
