 ## Summary
 
-- Machine code is hard for humans to parse, even in
-  [[Hexadecimal_number_system|hexadecimal]]
-
 - Assembly is one level up from machine code and provides a more human-friendly
   abstraction layer
 
 - An assembly instruction is a _mneumonic_ that comprises an "op code" plus
   operands
 
+## Detail
+
+### Example instruction
+
+We can translate the machine instruction `e3a07004` into the assembly
+instruction `mov r7, #4`. This translates to: _move the value number 4 to the
+register r7_.
+
+### Assemblers
+
+Although assembly is useful for humans, computers still work at the level of
+machine code. Therefore you need an **assembler** to translate the assembly code
+to machine code. An assembly language text file is fed into an assembler and a
+binary object file containing machine code is returned.
