 ## NearDiscovery
 NearDiscovery takes hostname and a bunch of settings in a builder pattern for the discovery mechanism. A NearDiscovery object allows the following discovery related self-explanatory APIs:

+It's required to stop listening on a previous instance of NearConnect (using NearConnect.stopReceiving()) so as to start listening on another instance (by using NearConnect.startReceiving()).
 This is because the same server port is used in each instance (<- could be made configurable later if deemed necessary).
 
 on startReceiving(), and on send() partial wakelocks are held and released on stopReceiving() and on send completion/failure respectively.

+***Note:* NearConnect should work even outside of a local network, except across NAT firewalls.**
+
+## Getting Started
+Add jitpack.io to your root build.gradle
+```
+allprojects {
+    repositories {
+        ...
+        maven { url "https://jitpack.io" }
+    }
+}
+```
+Then add the dependency in your project build.gradle
+```
+dependencies {
+    ...
+    compile 'com.github.adroitandroid:Near:v1.1'
+    ...
+}
+```
+You can find the latest version [here](https://github.com/adroitandroid/Near/releases/latest/).
+
+## Limitations
+- File transfers aren't easy yet. Services are background, API to take notification to start them in foreground, and listener methods to publish updates are on the TODO list.
