+# Kotlin Multiplatform Client ![Core](https://github.com/timehop/kotlin-mpp-template/workflows/Core/badge.svg)
+
+This repository is a template for creating a new Kotlin Mulitplatform project with Android and iOS
+targets using the latest build tooling.
+
+## IDE Setup
+
+Before you begin working with the project, install the Kotlin Multiplatform plugin for your IDE of 
+choice.
+
+[Android Studio](https://plugins.jetbrains.com/plugin/14936-kotlin-multiplatform-mobile)
+[XCode](https://github.com/touchlab/xcode-kotlin)
+
+## Versioning
+
+### Project
+
+The project version defaults to `development` unless built within Github actions which will compute
+the version using tag ref that started the build.
+
+### Dependencies
+
+Versions for all dependencies are defined in the gradle.properties file to centralize where updates
+to libraries happen. 
+
+## One Click Deployments
+
+To publish a version of the client library, push a tag to the default branch or use the Releases
+page to create a new release. This will publish a version that matches the tag name with a 
+package name generated when deploying from Github Actions in the format `${owner}.mpp` 
+
+## Integrating with an existing project
+
+Add the following to your Android build
+
+```kotlin
+repositories {
+    maven {
+        name = "github"
+        url = uri("https://maven.pkg.github.com/${owner}/${repository}")
+        credentials(PasswordCredentials)
+        // Optional filter to speed up dependency resolution
+        content {
+            includeGroup("${owner}.mpp")
+        }
+    }
+}
+
+dependencies {
+    implementation("${owner}.mpp:core")
+}
+```
+
+### buildSrc gradle.properties symlink
+
+To simplify updates to gradle.properties, the buildSrc gradle.properties file is symlinked to the
+root of the project.
+
+#### Windows symlinks
+
+Symlink creation requires admin access. If you have admin access delete the 
+buildSrc/gradle.properties and run the following command from the root of the project
+
+```shell script
+cmd> mklink /H "buildSrc/gradle.properties" "gradle.properties"
+```
