+# Build Firebase static frameworks
+
+[build.swift](build.swift) is a script that will build a static framework for
+one or more of FirebaseAuth, FirebaseCore, FirebaseDatabase, FirebaseMessaging,
+and FirebaseStorage.
+
+Frameworks built with this script can be used alongside the official Firebase
+CocoaPods and
+[zip](https://firebase.google.com/docs/ios/setup#frameworks) distributions.
+
+
+## Usage
+
+```
+$ ./build.swift -f FirebaseAuth -f FirebaseMessaging ....
+```
+or
+```
+$ ./build.swift -all
+```
+
+The script will output the location of the new frameworks when it finishes
+the build.
+
+
+## Issues
+
+* Xcode's module cache may not properly update after a framework is replaced.
+The workaround is `rm -rf ~/Library/Developer/Xcode/DerivedData/ModuleCache/`
+
+* To replace the 4.0.0 version of FirebaseDatabase, the leveldb-library pod
+will need to be linked in. Add `pod 'leveldb-library'` to your Podfile.
