Additionally to what was mentioned above, instructions are just like the rest of home brewing. It's DIY!
It's DIY for a good reason too! Simply put, there are many ways to get to the end product.
Like Craigerrr said, what are you working with? Your method will help define your processes. We all have tweaked our processes around the basics, make the wort, add the hops, cool the wort, pitch the yeast, ferment, bottle or keg, condition, then drink! All the steps in between have additional processes but there really is no one set of universal, one size fits all "instructions".
Unless you are using an All in One like a Bruzilla or a GrainFather, it's up to you. If you don't have a good LHBS where they have a boot camp or are part of "The Big Brew", I suggest watching a lot of You Tube and take notes. The learning is DIY too! Check out the BrewDay sheets on the site here, they are under the Tools tab. There's a check list you can download that can get you started as a high leve step by step outline..there's an All Grain and a BiB list a I recall.
You've got a good start already, you are asking questions and you are on a site where other brewers are willing to help!
