+# pchat: whisper-chat-example
+
+## Running the example
+
+The example assumes that there is a running Whisper v6 node exposing an RPC interface at URL `http://localhost:8545`. For this, you can use `geth` with the folloing parameters:
+
+    $ geth <usual p2p flags> --shh --rpc
+
+
+`--shh` is the option that enables Whisper v6 for the node.
+
+`--rpc` enables the HTTP RPC interface.
+
+## Download
+
+download your version from [here](https://github.com/mabdalrahman/pchat/releases/tag/v1.0.0-alpha1)
+
+## Installation From Source
+`pchat` requires Go 1.10.2 or later, [dep](github.com/golang/dep) to managing dependency package and [xgo](https://github.com/karalabe/xgo) for cross compile.
+
+```
+$ go get -u github.com/mabdalrahman/pchat
+```
+
+## Usage
+```
+pchat -username "user" 
+
+mandatory argument:
+     -username                     set your username
+
+optional arguments:
+     -privatekey                   set your private key
+
+```
