+## Manual integration
+
+When not using CocoaPods, Swift gRPC includes **vendored copies** of the
+gRPC Core library and BoringSSL (an OpenSSL fork that is used by
+the gRPC Core). These are built automatically in Swift Package
 Manager builds.
 
+After [building your project](#building-your-project), add the generated
+`SwiftGRPC.xcodeproj` to your project, and add build dependencies

+Please also note that your project will need to include the
+`SwiftProtobuf.xcodeproj` from
+[Swift Protobuf](https://github.com/apple/swift-protobuf) and
+the source files that you generate with `protoc`/[plugins](#getting-the-plugins).
+
+See [Echo](Examples/Echo) for a working Xcode-based
+example, and don't hesitate to file issues if you find any problems.
