+# Firebase Crashlytics SDK
+
+## Development
+
+Follow the subsequent instructions to develop, debug, unit test, and
+integration test FirebaseCrashlytics:
+
+### Prereqs
+
+- At least CocoaPods 1.6.0
+- Install [cocoapods-generate](https://github.com/square/cocoapods-generate)
+- For nanopb and GDT:
+    - `brew install protobuf nanopb-generator`
+    - `easy_install protobuf python`
+
+### To Develop
+
+- Run `Crashlytics/generate_project.sh`
+- `open gen/FirebaseCrashlytics/FirebaseCrashlytics.xcworkspace`
+
+You're now in an Xcode workspace generate for building, debugging and
+testing the FirebaseCrashlytics CocoaPod.
+
+### Running Unit Tests
+
+Open the generated workspace, choose the FirebaseCrashlytics-Unit-unit scheme and press Command-u.
+
+### Changing crash report uploads (using GDT)
+
+#### Update report proto
+
+If the crash report proto needs to be updated, follow these instructions:
+
+- Update `ProtoSupport/Protos/crashlytics.proto` with the new changes
+- Depending on the type of fields added/removed, also update `ProtoSupport/Protos/crashlytics.options`.
+ `CALLBACK` type fields in crashlytics.nanopb.c needs to be changed to `POINTER`
+ (through the options file). Known field types that require an entry in crashlytics.options are
+ `strings`, `repeated` and `bytes`.
+- Run `generate_project.sh` to update the nanopb .c/.h files.
