+# Linux Installation Cheatsheet
+
+## 1. Update the local packages
+
+  ```bash
+  sudo apt-get update
+  ```
+
+## 2. Install git
+
+  ```bash
+  sudo apt-get install git
+  ```
+
+## 3. Install Go
+
+Select linux and the download will begin.
+
+  ```bash
+  firefox https://golang.org/dl
+  ```
+
+## 4. Copy Go into the proper directory
+
+1. Find out the name of the downloaded file
+2. Use that filename to uncompress it
+
+    ```bash
+    gofile="DELETE_THIS_AND_TYPE_THE_NAME_OF_THE_DOWNLOADED_FILE_HERE (without its extension)"
+
+    tar -C /usr/local -xzf ~/Downloads/$gofile.tar.gz
+    ```
+
+3. Add `go/bin` directory to `$PATH` to be able to run the fundamental Go commands.
+
+    ```bash
+    echo 'export PATH=$PATH:/usr/local/go/bin' >> ~/.profile
+    ```
+
+4. Add "$HOME/go/bin" directory to $PATH
+
+    ```bash
+    echo 'export PATH=$PATH:$HOME/go/bin' >> ~/.profile
+    ```
+
+## Install Go Tools:
+
+* These are very handy tools to ease the development (like goimports)
+
+* `go get` cannot be usable without installing a code versioning program like Git which we already have got it above.
+
+* This will create `~/go` directory and will download go tools into there.
+
+    * This directory is also a place where you should put your code into.
+    (If you're not going to use Go Modules)
+
+    ```bash
+    go get -v -u golang.org/x/tools/...
+    ```
+
+## Install VSCode
+
+1. Open "Ubuntu Software" application
+2. Search for VSCode then click "Install"
+3. Install [Vim-Go](https://github.com/fatih/vim-go#install)
+
+## OPTIONAL STEP:
+
+1. Create a hello.go inside `$GOPATH/src`
+
+    ```bash
+    cat <<EOF > $GOPATH/src/hello.go
+    package main
+    
+    import "fmt"
+    
+    func main() {
+        fmt.Println("hello gopher!")
+    }
+    EOF
+    ```
+
+2. Go to Go source directory and run our sample program
+
+    ```bash
+    cd $GOPATH/src
+    go run hello.go
+    It should print: hello gopher!
+    ```
