 ## Issues & Caveats
 
+- Swift 5.3 required on host ([SR-13312](https://bugs.swift.org/browse/SR-13312))
 - There is no "direct" Xcode support yet, i.e. the package needs to be
   created using a `Package.swift` (vs create a new tool project in Xcode).
   We might address that and even provide a SwiftXcode style Lambda Xcode
   template. Direct deployment from within Xcode should be possible.
+  ([Issue 2](https://github.com/SwiftXcode/swift-lambda/issues/2))
 - C++ support seems b0rked right now. Regular C code compile just fine
-  (e.g. SwiftNIO includes some).
+  (e.g. SwiftNIO includes some). 
+  ([SPMDestinations Issue #4](https://github.com/SPMDestinations/homebrew-tap/issues/4))
 - `swift lambda build` has some support for static linking already builtin,
   but it doesn't fully work yet. To be fixed.
   (static linking reduces the size of the zip and further improves Lambda
    startup time).
+  ([Issue 3](https://github.com/SwiftXcode/swift-lambda/issues/3))
 - There is no Swift 5.3 toolchain for Amazon Linux yet (just 5.2).
+  ([SPMDestinations Issue #5](https://github.com/SPMDestinations/homebrew-tap/issues/5))
 - The X toolchains only have the packages that seemed necessary. If someone
   needs additionals ones please file an issue (the toolchains can carry lots
   of dev packages, that's perfectly fine).
