+"Good, the new computer seems to be working correctly!  Keep it nearby during this mission - you'll
+probably use it again. Real Intcode computers support many more features than your new one, but
+we'll let you know what they are as you need them."
+
+"However, your current priority should be to complete your gravity assist around the Moon. For this
+mission to succeed, we should settle on some terminology for the parts you've already built."
+
+Intcode programs are given as a list of integers; these values are used as the initial state for the
+computer's memory. When you run an Intcode program, make sure to start by initializing memory to the
+program's values. A position in memory is called an address (for example, the first value in memory
+is at "address 0").
+
+Opcodes (like 1, 2, or 99) mark the beginning of an instruction.  The values used immediately after
+an opcode, if any, are called the instruction's parameters.  For example, in the instruction
+1,2,3,4, 1 is the opcode; 2, 3, and 4 are the parameters. The instruction 99 contains only an opcode
+and has no parameters.
+
+The address of the current instruction is called the instruction pointer; it starts at 0.  After an
+instruction finishes, the instruction pointer increases by the number of values in the
+instruction; until you add more instructions to the computer, this is always 4 (1 opcode + 3
+parameters) for the add and multiply instructions. (The halt instruction would increase the
+instruction pointer by 1, but it halts the program instead.)
+
+"With terminology out of the way, we're ready to proceed. To complete the gravity assist, you need
+to determine what pair of inputs produces the output 19690720."
+
+The inputs should still be provided to the program by replacing the values at addresses 1 and 2,
+just like before.  In this program, the value placed in address 1 is called the noun, and the value
+placed in address 2 is called the verb.   Each of the two input values will be between 0 and 99,
+inclusive.
+
+Once the program has halted, its output is available at address 0, also just like before. Each time
+you try a pair of inputs, make sure you first reset the computer's memory to the values in the
+program (your puzzle input) - in other words, don't reuse memory from a previous attempt.
+
+Find the input noun and verb that cause the program to produce the output 19690720. What is 100 *
+noun + verb? (For example, if noun=12 and verb=2, the answer would be 1202.)
