 ## $GOPATH
 
-Go takes a unique approach to manage the code files with the introduction of a `$GOPATH` directory which contains all the go code in the machine. Note that this is different from the `$GOROOT` environment variable which states where go is installed on the machine. We have to define the `$GOPATH` variable before using the language, in *nix systems there is a file called `.profile` we need to append the below export statement to the file. The concept behind gopath is a novel one, where we can link to any go code at any instant of time without ambiguity.

+On Unix-like systems, the variable should be used like this:

 In Windows, you need to create a new environment variable called GOPATH, then set its value to `c:\mygo`( ***This value depends on where your workspace is located*** )
 
-It's OK to have more than one path (workspace) in `$GOPATH`, but remember that you have to use `:`(`;` in Windows) to break them up. At this point, `go get` will save the content to your first path in `$GOPATH`. It is highly recommended to not have multiples versions, the worst case is to create a folder by the name of your project right inside `$GOPATH`, it breaks everything that the creators were wishing to change in programming with the creation of go language because when you create a folder inside `$GOPATH` you will reference your packages as directly as <packagename>, and this breaks all the applications which will import your package because the `go get` won't find your package. Please follow conventions, there is a reason conventions are created.

 (The format of environment variables in Windows is `%GOPATH%`, however this book mainly follows the Unix-style, so Windows users need to replace these yourself.)
