For almost every document that I type in LaTeX, I start by opening one of the most recent documents that I made, copying all of the packages and pre-set commands, and pasting them in the new document. This is because I have a lot of packages that I use on a regular basis. However, it gets pretty annoying and my preamble is messy.
I would like to create some sort of a template that contains all of the packages and commands that I normally use so that when I decide to start a new document I can use a single command and call on a file that has all of those packages already set up. Is something like this possible?
Thank you for your time
