 ## Usage
 
 1. Generate the json result by `xcrun xccov view --only-targets --json`
+    ```bash
+    # target: https://github.com/KazuCocoa/test.examples
+    $ git clone https://github.com/KazuCocoa/test.examples && cd test.examples
+    $ xcodebuild -workspace test.examples.xcworkspace -scheme test.examples -derivedDataPath Build/ -destination 'platform=iOS Simulator,OS=11.3,name=iPhone 7' -enableCodeCoverage YES clean build test CODE_SIGN_IDENTITY="" CODE_SIGNING_REQUIRED=NO
     ```
-    $ xcrun xccov view --only-targets --json Build/Logs/Test/*.xccovreport > result.json
-    ```
 2. Read the JSON and get a particular line coverage
     ```ruby
+    xccov = Xccov.new
+    xccov.help
+    json = xccov.view '--only-targets', '--json', 'Build/Logs/Test/*.xccovreport'
+    parsed = Xccov::Parse.new(json: json)
+    parsed.targets_line_coverage["test.examples.app"] #=> 0.35
+
+    # or
+    # $ xcrun xccov view --only-targets --json Build/Logs/Test/*.xccovreport > result.json
     parsed = Xccov::Parse.new(file: './result.json')
     parsed.targets_line_coverage["test.examples.app"] #=> 0.35
     ```
