+## Package structure
+
+Native modules can't be built outside the context of a React Application, this makes it difficult to run unit tests
+on the native side functionality. To get around this limitation the actual Android and iOS native source files for this
+module are in native-src/ structured as if they were plugins within an example app.
+
+The source files are then copied over to the android/ and ios/ directories at build time following the structure RN
+expects them to have when being packaged as libraries. To avoid editing the wrong spot the source files under those
+directories are git ignored and only generated as needed during build.
+
+## Testing
+
+### Testing Android
+
+Tests can be run from Android Studio by adding native-src/android as a Project or from the CLI with `yarn android-test`
+
+### Testing iOS
+
+TODO
+
+## Building
+
+`yarn build` will copy the needed files to android/ and ios/ and then compile the package as normal
