 5 | ## How to implement it in your project
 6 | 
 7 | 1. Check the `Package.swift` file to see how to add SwiftLint to your Swift
 8 |    package.
 9 | 
10 | 2. Copy the `Plugins/SwiftLintXcode/plugin.swift` file to your project.
11 | 
12 | 3. Done! Build your package with Xcode and SwiftLint will display warnings and
13 |    errors in Xcode.
14 | 
15 | This is the only way I was able to get it working in Xcode 13.3. Ideally, the
16 | plugin itself could be declared in some shared repository that everyone could
17 | use, so they wouldn't need to manually add swiftlint binary checksums or
18 | implement the plugin. However, I wasn't able to get that working.
