allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

and to your app build.gradle:

AndroidX
dependencies {
    implementation 'com.github.VladimirWrites:Lemniscate:2.0.0'
}
Android Support Library
dependencies {
    implementation 'com.github.VladimirWrites:Lemniscate:1.4.5'
}
