+
+if you don't have your GOPATH exported, do so with
+export GOPATH=$(go env GOPATH)
+
+you have a GOPATH which points to e.g. ~/go/
+this is where everything in go is stored.
+
+it has three directories,
+ - src
+ - pkg
+ - bin
+
+installed programs have their executables stored in bin
+all your project and the src code of other people's projects are in src, with paths identifying them e.g.
+src/github.com/jesseduffield/gitgot
+
+If you want to make an executable, give every file in your project directory `package main`, otherwise if you want to make a package, name everything `package mypackage`. This name should be the name of the project directory for your project.
+
+to install a program, inside the project folder
+go install
+
+This adds the program to /bin
+
+to build a package, inside the project folder
+go build
+
+this adds the package to /pkg so that it can be linked easily in the future.
+
+to build and run your program just do this:
+
+~/github.com/jesseduffield/gitgot:
+▶ go install && gitgot
+
+-----------------------------------------------------------
+    BUILD SYSTEMS
+-----------------------------------------------------------
+
+Currently for installs I'm using
+/Users/jesseduffieldduffield/Library/Application Support/Sublime Text 3/Packages/User/custom_go_install.sublime-build
+
+note that the argument to go install should be the directory from the end of /src/ onwards.
