+An implementation of a Chat Server with [Cloud Haskell](http://haskell-distributed.github.io/)
+
+
+# Installation
+
+Clone this repository and run `stack install` in its root folder.
+
+
+# Run server
+
+To run the server, you must provide the following arguments:
+
+ - `host`: Address of the host machine for the chat server.
+ - `port`: Port where the server is to be served.
+ - `room`: Name for this chat room.
+
+For example:
+
+```
+chatServer --host 192.168.0.33 --port 8080 --room myChat
+```
+
+As soon as the server is launched it will prompt its `EndPointAddress`, which is needed for clients to establish a connection.
+The prompt log will look like the following:
+
+```
+Server launched at: 192.168.0.33:8080:0
+```
+
+# Run client
+
+To run the client, you must provide the following arguments:
+
+- `address`: [EndPointAddress](http://haskell-distributed.github.io/tutorials/tutorial-NT2.html) of the remote (or local) machine serving the chat room.
+- `host`: Address of the host machine for the chat client.
+- `port`: Port where the client is to be served.
+- `room`: Name of the chat room this client will connect to.
+
+
+For example:
+
+```
+chatClient --address 192.168.0.33:8080:0 --host 127.0.0.1 --port 8880 --room myChat
+```
+
+Note that the `EndPointAddress` you must provide is the value provided by the chat server once it has been launched.
