 # queryservice-gateway
+A proxy for use in the WBStack suite of applications for Wikibase Cloud.
+
+This acts as a reverse proxy using [redbird](https://github.com/OptimalBits/redbird) to route requests to a specific blazegraph namespace depending which wikibase sparql queries are targetting.
+
+The blazegraph namepace is looked up from the [platform api](https://github.com/wbstack/api) and cached.
