 ## Installation
 
-SwiftGraph 3.0 requires Swift 5 (Xcode 10.2). Use SwiftGraph 2.0 for Swift 4.2 (Xcode 10.1) support, SwiftGraph 1.5.1 for Swift 4.1 (Xcode 9), SwiftGraph 1.4.1 for Swift 3 (Xcode 8), SwiftGraph 1.0.6 for Swift 2 (Xcode 7), and SwiftGraph 1.0.0 for Swift 1.2 (Xcode 6.3) support. SwiftGraph runs fine and is tested on Linux.

 ### Search
 Search methods are defined in extensions of `Graph` and `WeightedGraph` in `Search.swift`.
