+[![Build Status](https://travis-ci.org/Massad/gin-boilerplate.svg?branch=master)](https://travis-ci.org/Massad/gin-boilerplate)
+[![Join the chat at https://gitter.im/Massad/gin-boilerplate](https://badges.gitter.im/Massad/gin-boilerplate.svg)](https://gitter.im/Massad/gin-boilerplate?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
+
+Welcome to **Golang Gin boilerplate**!
+
+The fastest way to deploy a restful api's with [Gin Framework](https://gin-gonic.github.io/gin/) with a structured project that defaults to **PostgreSQL** database and **Redis** as the session storage.
+
+## Configured with
+
+* [go-gorp](github.com/go-gorp/gorp): Go Relational Persistence
+* [RedisStore](https://github.com/gin-gonic/contrib/tree/master/sessions): Gin middleware for session management with multi-backend support (currently cookie, Redis).
+* Built-in **CORS Middleware**
+* Feature **PostgreSQL 9.4** JSON queries
+* Unit test
+
+### Installation
+
+```
+$ go get github.com/Massad/gin-boilerplate
+```
+
+```
+$ cd $GOPATH/src/github.com/Massad/gin-boilerplate
+```
+
+```
+$ go get -t -v ./...
+```
+
+> Sometimes you need to get this package manually
+```
+$ go get github.com/bmizerany/assert
+```
+
+You will find the **database.sql** in `db/database.sql`
+
+And you can import the postgres database using this command:
+```
+$ psql -U postgres -h localhost < ./db/database.sql
+```
+
+## Running Your Application
+
+```
+$ go run *.go
+```
+
+## Building Your Application
+
+```
+$ go build -v
+```
+
+```
+$ ./gin-boilerplate
+```
+
+## Testing Your Application
+
+```
+$ go test -v ./tests/*
+```
+
+
+## Import Postman Collection (API's)
+You can import from this [link](https://www.getpostman.com/collections/ac0680f90961bafd5de7). If you don't have **Postman**, check this link [https://www.getpostman.com](https://www.getpostman.com/)
