 ## Integrating Aztec in your project
 
-The library is not ready for prime time yet, so it's not published on Maven
-Central. Currently the library is distributed as an [alpha build](https://github.com/wordpress-mobile/AztecEditor-Android/releases).
+You can import Aztec into your project using Jitpack:
+```gradle
+repositories {
+    maven { url "https://jitpack.io" }
+}
+```
+```gradle
+dependencies {
+    api ('com.github.wordpress-mobile.WordPress-Aztec-Android:aztec:v1.3.1')
+}
+```
 
 Brave developers can either use the project as a source distribution
-or have fun with JitPack at their own risk:
+or have fun with the latest snapshot at their own risk:
 
 ```gradle
-compile ('com.github.wordpress-mobile.WordPress-Aztec-Android:aztec:develop-SNAPSHOT')
+dependencies {
+    api ('com.github.wordpress-mobile.WordPress-Aztec-Android:aztec:develop-SNAPSHOT')
+}
 ```
 
-When Aztec is ready, we'll publish the artifact in Maven.

 ## Code formatting
 
 We use [ktlint](https://github.com/shyiko/ktlint) for Kotlin linting. You can run ktlint using `./gradlew ktlint`, and you can also run `./gradlew ktlintFormat` for auto-formatting. There is no IDEA plugin (like Checkstyle's) at this time.
