-# Contributing to React Native Async Storage
+# Contributing to Async Storage
 
-Thank you for helping out with Async Storage!
-We'd like to make contributions as pleasent as possible, so here's a small guide of how we see it. Happy to hear your feedback about anything, so please let us know.
-
-
-## Tests
-We use `flow` for type check, `eslint` with `prettier` for linting/formatting, `jest/detox` for tests (unit and e2e). All tests are run on CircleCI for all opened pull requests, but you should use them locally when making changes.
-
-* `yarn test`: Run all tests, except for e2e (see note below).
-* `yarn test:lint`: Run `eslint` check.
-* `yarn test:flow`: Run `flow` type check.
-* `yarn test:e2e:<ios|android>`: Runs e2e tests. Before you can run it, you should build the app that can be run, by using `yarn build:e2e:<ios|android>`.
-
-
-## Sending a pull request
-When you're sending a pull request:
-
-* Communication is a key. If you want fix/add something, please open new/find existing issue, so we can discuss it.
-* We prefer small pull requests focused on one change, as those are easier to test/check.
-* Please make sure that all tests are passing on your local machine.
-* Follow the template when opening a PR.
-
-
-## Commits and versioning
-All PRs are squashed into `master` branch and wrapped up in a single commit, following [conventional commit message](https://www.conventionalcommits.org/en/v1.0.0-beta.3). Combined with [semantic versioning](https://semver.org/), this allows us to have a frequent releases of the library.
-
-*Note*: We don't force this convention on Pull Requests from contributors, but it's a clean way to see what type of changes are made, so feel free to follow it. 
-
-
-Most notably prefixes you'll see:
-
-* **fix**: Bug fixes, triggers *patch* release
-* **feat**: New feature implemented, triggers *minor* 
-* **chore**: Changes that are not affecting end user (CI config changes, scripts, ["grunt work"](https://stackoverflow.com/a/26944812/3510245))
-* **docs**: Documentation changes.
-* **perf**: A code change that improves performance.
-* **refactor**: A code change that neither fixes a bug nor adds a feature.
-* **test**: Adding missing tests or correcting existing tests.
-
-
-## Release process
-We use [Semantic Release](http://semantic-release.org) to automatically release new versions of the library when changes are merged into `master` branch, which we plan to keep stable. Bug fixes take priority in the release order.
-
-## Reporting issues
-You can report issues on our [bug tracker](https://github.com/react-native-community/react-native-async-storage/issues). Please search for existing issues and follow the issue template when opening an one.

+# Async Storage
 
-An asynchronous, unencrypted, persistent, key-value storage system for React Native.
+A storage system for React Native.
 
+## Work in progress
 
-## Getting Started
+Async Storage v2 is still under development.
 
+If you're looking for published and operational Async Storage version, please check out [`LEGACY`](https://github.com/react-native-community/async-storage/tree/LEGACY) branch.
 
-```
-# Install
-$ yarn add @react-native-community/async-storage
+If you'd like to see the progress of v2, [please visit Project page.](https://github.com/react-native-community/async-storage/projects/1) 
 
-# Link
-$ react-native link @react-native-community/async-storage
-```
 
-See docs for [manual linking guide.](docs/Linking.md)
-
-**Note:** For iOS project using `pods`, run:
-	```
-	$ cd ios/ && pod install
-	```
-
-
-## Usage
-
-### Import
-
-```js
-import AsyncStorage from '@react-native-community/async-storage';
-```
-
-### Store data
-```jsx
-
-storeData = async () => {
-  try {
-    await AsyncStorage.setItem('@storage_Key', 'stored value')
-  } catch (e) {
-    // saving error
-  }
-}
-
-```
-
-### Read data
-```jsx
-
-getData = async () => {
-  try {
-    const value = await AsyncStorage.getItem('@storage_Key')
-    if(value !== null) {
-      // value previously stored
-    }
-  } catch(e) {
-    // error reading value
-  }
-}
-
-```
-### Advanced
-See docs for [api and more examples](docs/API.md) or [advanced usages](docs/advanced).
-
-## Writing tests
-
-Using [Jest](https://jestjs.io/) for testing? Make sure to check out [docs on how to integrate it with this module.](./docs/Jest-integration.md)
