Greetings fellow earthlings I have an Arduino uno and every time I try and upload the code to the board the port doesn't show up. Any suggestions on what to do? 
What computer/operating system/version?
Is it an official, genuine Arduino/Genuino Uno or one of clones?
Have you been through the steps in the troubleshooting guide?
So you mean that the port menu is greyed out? That typically indicates driver problems.
Are you using a clone Arduino? Check the markings on the black chip near the USB port - many clones use a different serial adapter (almost always a CH340G, because they're insanely cheap). The official Uno uses an atmega 16u2 as a serial adapter.
The IDE does not come with drivers for anything that wasn't used on an official board, so for most clones, you have to download and install the drivers yourself (google will find them).
