+- [Step By Step](#Step-By-Step)
+
+## Step By Step
+
+All steps necessary to make this example project.
+
+### Create a mod init
+
+All libs in Golang have a module name.
+This is for a package manage for Golang, like a npm/yarm for nodeJS, gradlew/mavem for Java, compose for PHP, mix for Elixir and many more.
+
+```bash
+go mod init github.com/ruyjfs/example-golang
+```
+
+> See: go.mod
+
+### Create a file main.go - The Hello World
+
+```bash
+ echo '' >> main.go
+```
+
+```go
+package main
+
+import (
+	"log"
+)
+
+func main() {
+	log.Printf("Hello World!")
+}
+```
+
+Run to see you first hello world
+
+```bash
+go run main.go
+```
+
+### Install GraphQL
+
+```bash
+go run github.com/99designs/gqlgen init
+```
+
+To generate graphql files.
+
+```bash
+gqlgen generate
+```
+
+> On docker
+
+```bash
+~/go/bin/gqlgen generate
+```
