+## Building
+
+### Requirements
+
+- Xcode 10.2.1
+- Bazel 0.25.3 (can't use 0.26.0 because of [this issue](https://github.com/bazelbuild/tulsi/issues/86))
+
+### iOS
+
+#### Build the iOS static framework:
+
+```
+bazel build ios_dist --config=ios
+```
+
+This will yield an `Envoy.framework` in the [`dist` directory](./dist).
+
+#### Run the Swift app:
+
+```
+bazel run //examples/swift/hello_world:app --config=ios
+```
+
+#### Run the Objective-C app:
+
+```
+bazel run //examples/objective-c/hello_world:app --config=ios
+```
+
+### Android
+
+#### Build the Android AAR:
+
+```
+bazel build android_dist --config=android
+```
+
+#### Run the Java app:
+
+```
+bazel mobile-install //examples/java/hello_world:hello_envoy --fat_apk_cpu=x86
+```
+
+If you have issues getting Envoy to compile locally, see the
+[Envoy docs on building with Bazel](https://github.com/envoyproxy/envoy/tree/master/bazel).
