+# Contributing notes
+
+## Local setup
+
+The easiest way to make a local development setup is to use Docker Compose: `make env-run` on Linux.
+
+You can run ClickHouse client with `make clickhouse-client`.
+
+
+## Vendoring
+
+We use [dep](https://github.com/golang/dep) to vendor dependencies. Please use released version, i.e. do not `go get`
+from `master` branch.
