+# Ad Service
+
+The Ad service provides advertisement based on context keys. If no context keys are provided then it returns random ads.
+
+## Building locally
+
+The Ad service uses gradlew to compile/install/distribute. Gradle wrapper is already part of the source code. To build Ad Service, run:
+
+```
+./gradlew installDist
+```
+It will create executable script src/adservice/build/install/hipstershop/bin/AdService
+
+### Upgrading gradle version
+If you need to upgrade the version of gradle then run
+
+```
+./gradlew wrapper --gradle-version <new-version>
+```
+
+## Building docker image
+
+From `src/adservice/`, run:
+
+```
+docker build ./
+```
