+**XcodeSnippet** provides the ability to save or use the codeSnippet that you set up.
+
+## Snippet as Swift packages
+The usage of XcodeSnippet is very similar to that of Snippet in traditional Xcode.
+Projects are defined as Swift Packages, all of which use the default format type-safe swift code.
+
+```swift
+import XcodeSnippet
+
+struct SnippetEx: Snippet {
+    var xcodeSnippet: [XcodeSnippet] = []
+}
+
+_ = try snippetEx().install()
+```
+You can use it like this. XcodeSnipet is really simple, right?
+
+## Installation
+XcodeSnippet was deployed as Swift Package Manager. Package to install in a project. Add as a dependent item within the swift manifest.
+```swift
+let package = Package(
+    ...
+    dependencies: [
+        .package(url: "https://github.com/JiHoonAHN/XcodeSnippet.git", from: "0.0.1")
+    ],
+    ...
+)
+```
+Then import the XcodeSnipet from the location you want to use.
+```swift
+import XcodeSnippet
+```
+
+XcodeSnippet also comes with command-line tools to easily create projects for easy project support.
+```
+$ git clone https://github.com/JiHoonAHN/XcodeSnippet.git
+$ cd XcodeSnippet
+$ make
+```
+
+Then run the instructions on how to use `XcodeSnippet help`.
+
+## Quick start
+To start XcodeSnippet faster, clone this repository, install the command-line tool, and run `make` within the replicated folder.
+
+```
+$ git clone https://github.com/JiHoonAHN/XcodeSnippet.git
+$ cd XcodeSnippet
+$ make
+```
+
+_**Note**: If you encounter an error while running `make`, ensure that you have your Command Line Tools location set from Xcode's preferences. It's in Preferences > Locations > Locations > Command Line Tools. The dropdown will be blank if it hasn't been set yet._
+
+Then, create a new folder for your new Snippet project and simply run `xcodeSnippet new` within it to get started:
+
+```
+$ mkdir MySnippet
+$ cd MySnippet
+$ xcodeSnippet new
+```
+Finally, run `open Package.swift` to open up the project in Xcode to start making your snippet Setting!
