-You can try the SNAPSHOT version:
+AppCompat, CardView, RecyclerView library is required by Material library.
 
 ```gradle
 dependencies {
-   compile 'com.github.rey5137:material:1.2.3.1-SNAPSHOT'
-}
-```
-Make sure to add the snapshot repository:
-
-```gradle
-repositories {
-    maven {
-        url "https://oss.sonatype.org/content/repositories/snapshots"
-    }
-}
