Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.shrikanthkr:saveinstance-api:'
	}
	dependencies {
		implementation("com.github.shrikanthkr:saveinstance-api:")
	}
	<dependency>
	    <groupId>com.github.shrikanthkr</groupId>
	    <artifactId>saveinstance-api</artifactId>
	    <version></version>
	</dependency>

                            
    libraryDependencies += "com.github.shrikanthkr" % "saveinstance-api" % ""
        
        

                            
    :dependencies [[com.github.shrikanthkr/saveinstance-api ""]]
