 ## Install
 
 ```shell
-go get "github.com/circa10a/go-aws-news"
+go get -u "github.com/circa10a/go-aws-news"
 ```
 
 ## Usage
 
 Methods return a slice of structs which include the announcement title, a link, and the date it was posted as well an error. This allows you to manipulate the data in whichever way you please, or simply use `Print()` to print a nice ASCII table to the console.
 
+#### Get Today's news
+
+```go
+news, err := awsnews.Today()
+if err != nil {
+	// Handle error
+}
+```
+
+#### Get Yesterday's news
+
+```go
+news, _= awsnews.Yesterday()
+```
+
+#### Get all news for the month
+
+```go
+news, _ = awsnews.ThisMonth()
+```
+
+#### Gets from a previous month
+
+```go
+// Custom timeframe(June 2019)
+news, err = awsnews.Fetch(2019, 06)
+```
+
+#### Print out announcements
+
+```go
+news, _ = awsnews.ThisMonth()
+news.Print()
+// Console output
+// +--------------------------------+--------------+
+// |          ANNOUNCEMENT          |     DATE     |
+// +--------------------------------+--------------+
+// | Amazon Cognito now supports    | Jan 10, 2020 |
+// | CloudWatch Usage Metrics       |              |
+// +--------------------------------+--------------+
+// | Introducing Workload Shares in | Jan 10, 2020 |
+// | AWS Well-Architected Tool      |              |
+// +--------------------------------+--------------+
+//
+```
+
+#### Loop over news data
+
+```go
+// Loop slice of stucts of announcements
+// For your own data manipulation
+news, _ = awsnews.Fetch(time.Now().Year(), int(time.Now().Month()))
+for _, v := range news {
+	fmt.Printf("Title: %v\n", v.Title)
+	fmt.Printf("Link: %v\n", v.Link)
+	fmt.Printf("Date: %v\n", v.PostDate)
+}
+```
+
+#### Get news as JSON
+
+```go
+news, _ = awsnews.ThisMonth()
+json, jsonErr := news.JSON()
+if jsonErr != nil {
+	log.Fatal(err)
+}
+fmt.Println(string(json))
+```
+
+#### Get news about a specific product
+
 ```go
 package main

+	for _, v := range n {
+		if strings.Contains(v.Title, "EKS") {
+			myEKSAnnouncements = append(myEKSAnnouncements, v)
+		}
+	}
+	return myEKSAnnouncements
