+## Task 2
+
+### Structure
+***
+1. **lib:** .jar files downloaded from [apache](https://archive.apache.org/dist/ws/xmlrpc/binaries/). the downloaded file is extracted and the contents of the `lib` directory copied in here.
+2. **out:** output binaries in packages `server` and `client`
+3. **src:** source code in 2 packages `client` and `server`
+
+### How to run
+***
+1. First we compile the code (in linux using the following command)
+    ```bash
+    # the "lib/*" tells jvm to include these libraries
+    javac -cp "lib/*" -d out $(find src -name "*.java")
+    ```
+
+2. Then we start the server. again run the following command
+    ```bash
+    java -cp "out:lib/*" server.Server
+    ```
+
+3. And finaly we run the client as such
+    ```bash
+    java -cp "out:lib/*" client.Client
+    ```
