+GridView is a free, and open-source library for SwiftUI that makes creating grids easier and much cleaner.
+* **Improves code quality.** Create a grid using `GridView` constructor - simply pass your data and we'll deal with the rest. Simple as never!
+* **Designed for SwiftUI.** While developing the library, we have used the power of SwiftUI to give you powerful tool to speed up your implementation process.
+

+
+# Getting Started
+### ✋ Requirements
+
+| **Platforms** | **Minimum Swift Version** |
+|:----------|:----------|
+| iOS 14+ | 5.0 |
+
+### ⏳ Installation
+
+#### [Swift Package Manager][spm]
+Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the Swift compiler.
+
+Once you have your Swift package set up, adding Navigattie as a dependency is as easy as adding it to the `dependencies` value of your `Package.swift`.
+
+```Swift
+dependencies: [
+    .package(url: "https://github.com/Mijick/GridView", branch(“main”))
+]
+``` 
+                      
+<br>
+
+# Usage
+### 1. Call initialiser
+To declare a Grid for your data set, call the constructor:
+
+```Swift
+struct ContentView: View {
+    private let data = [SomeData]()
+
+    var body: some View {
+        GridView(data, id: \.self) { element in
+            SomeItem(element: element)
+        }
+    }
+}
+```
+
+### 2. Customise Grid
+Your GridView can be customised by calling `configBuilder` inside the initialiser:
+
+```Swift
+struct ContentView: View {
+    private let data = [SomeData]()
+
+    var body: some View {
+        GridView(data, id: \.self, content: SomeItem.init, configBuilder: { $0
+            .insertionPolicy(.fill)
+            .columns(4)
+            .verticalSpacing(12)
+        })
+    }
+}
+```
+
+
+### 3. Declare number of columns
+You can change the number of columns of an item by calling .columns of Item:
+```Swift
+struct ContentView: View { ... }
+struct SomeItem: View {
+    ...
+
+    var body: some View {
+        ...
+            .columns(2)
+    }
+}
+```
