 **ThreadPoster is in public beta**. I'm actively looking for feedback on project's structure, naming and usability. Bug reports are also welcome, of course.
 
-## Usage
+## Install
+
+To use ThreadPoster in your project, add this line to your Gradle dependencies configuration:
+
+```
+implementation 'com.techyourchance.threadposter:threadposter:0.8.0'
+```
 
+## Usage
 At the core of this library are two simple classes: `UiThreadPoster` and `BackgroundThreadPoster`.
 
+Code style note: if you're concerned with "boilerplate", you can replace explicit `Runnables` in the examples below with lambdas.
