 # GO GRPC BASIC
 
-### Requirements ( Do It Letter )
+## Requirements
+check other branch to step by step create project 
+### Validate Go Installation
+```bash
+$ go version
+go version go1.18.3 linux/amd64
+```
+
+### Validate GOPATH
+```bash
+echo $GOPATH
+```
+
+### Start Project in Go
+```bash
+cd $GOPATH/src
+mkdir -p github.com/ajikamaludin/go-grpc_basic 
+cd github.com/ajikamaludin/go-grpc_basic 
+go mod init github.com/ajikamaludin/go-grpc_basic
+go mod tidy
+```
+
+### Install Protoc
+Linux : Download zip file, extract zip file to ~/.local/, add PATH ~/.local/bin
+please read documentation from this link for more detail information
+```
+https://grpc.io/docs/protoc-installation/
+```
 
+### Validate Protoc Installation
+```bash
+$ protoc --version
+libprotoc 3.21.2
+```
+
+### Install Protoc Dependecy for Golang
+```bash
+# protoc-gen-go
+go install github.com/golang/protobuf/protoc-gen-go@latest
+# proto (optional, execute in project dir)
+go get google.golang.org/protobuf/proto@latest
+# protoc-gen-grpc-gateway
+go install github.com/grpc-ecosystem/grpc-gateway/protoc-gen-grpc-gateway@latest
+# protoc-gen-swagger
+go install github.com/grpc-ecosystem/grpc-gateway/protoc-gen-swagger@latest
+```
+
+### Add PATH
+add to your ~/.bashrc or ~/.zshrc file
+```bash
+export PATH="$PATH:$GOPATH/bin"
+```
+### Validate Protoc Dependency Golang Installation
+```bash
+~ ❯ ls $GOPATH/bin
