+
+## About
+
+This project is a Crossbow Plugin for [Google Play Core libraries](https://developer.android.com/guide/playcore) written in Rust and Kotlin.
+
+## Installation
+
+> **Important:** Before using this plugin please read more about [Google Play Core libraries](https://developer.android.com/guide/playcore) and [In-app updates](https://developer.android.com/guide/playcore/in-app-updates).
+
+Just add Rust dependencies like this:
+
+```toml
+[dependencies]
+crossbow = "0.2.0"
+[target.'cfg(target_os = "android")'.dependencies]
+play-core = "0.2.0"
+```
+
+And finally, add this to your Crossbow Android configuration:
+
+```toml
+[package.metadata.android]
+plugins_remote = ["com.crossbow.play_core:play_core:0.2.0"]
+```
+
+> That's it, now you can start using Play Core!
+
+## Usage
+
+First step is plugin initialization. In your rust project, you will need to initialize `Crossbow` instance and then get **Android** plugin:
+
+```rust
+#![cfg(target_os = "android")]
+
+use crossbow::android::*;
+let crossbow = CrossbowInstance::new();
+let play_core: play_core::PlayCorePlugin = crossbow.get_plugin()?;
+```
+
+After plugin initialization you can use supported features. For example to start connection and query purchases you can use:
+
+```rust
+play_core.check_update()?;
+play_core.in_progress_update()?;
+```
+
+To read signals:
+
+```rust
+if let Ok(signal) = play_core.get_receiver().recv().await {
+    println!("Signal: {:?}", signal);
+}
+```
+
+Complete documentation you can find [here](https://docs.rs/play-core/).
+
+## Future work
+
+Ideally we will get rid of the Java wrapper and will create C++ wrapper around [Google Play Core native](https://developer.android.com/reference/native/play/core) - so that it will support all features and will work faster than with JNI. If you want to help us with it - welcome!

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
