-Babelfish Scala client
+## Babelfish Scala client [![Build Status](https://travis-ci.org/bzz/client-scala.svg?branch=master)](https://travis-ci.org/bzz/client-scala)
+
+This a pure Scala implementation of [Babelfish](https://doc.bblf.sh/) client.
+It uses [ScalaPB](https://scalapb.github.io/grpc.html) for Protobuf/gRPC code generation.
+
+### Usage
+
+API
+```scala
+import scala.io.Source
+import org.bblfsh.client.BblfshClient
+
+val client = BblfshClient("0.0.0.0", 9432)
+
+val filename = "/path/to/file.py" // client responsible for encoding it to utf-8
+val fileContent = Source.fromFile(filename).getLines.mkString
+println(client.parse(filename, fileContent))
+```
+
+Command line
+```
+java -jar ./target/client-assembly-0.0.1.jar file.py
+```
+
+### Build
+
+```
+./sbt assembly
+```
+
+gRPC/protobuf are re-generate from `src/main/proto` on every `./sbt compile` and are stored under `./target/scala-2.11/src_managed/`
