 # React Native CLI
 
-Command line tools to interact with React Native projects.
+Command line tools that ship with [`react-native`](https://github.com/facebook/react-native) in form of the `@react-native-community/cli` package.
+
+> It exposes `react-native` binary, so your can call `yarn react-native` or `npx react-native` directly from your project.

 ## About
 
-This repository contains tools and helpers for React Native projects in form of a CLI. We want to make a couple of things clear for you first:
+This repository contains tools and helpers for React Native projects in form of a command line tool. There's been quite some confusion around that since the extraction from React Native core. Let's clear them up:
 
-- this is a monorepo;
-- there are currently two CLIs: the actual one called [`@react-native-community/cli`](./packages/cli) that does all the job and global [`react-native-cli`](./packages/global-cli) which is used as its proxy and installation helper;
+- There are currently two CLIs:
+  - [`@react-native-community/cli`](./packages/cli) – **the one used directly by `react-native`**. That makes it a transitive dependency of your project.
+  - [`react-native-cli`](./packages/global-cli) – an optional global convenience package, which is a proxy to [`@react-native-community/cli`](./packages/cli) and global installation helper. **Please consider it legacy, because it's not necessary anymore**.
+- When we say "the CLI" we mean `@react-native-community/cli`.
+- We update the CLI independently of React Native itself. Please see [how to use the latest version](#updating-the-cli).
+- This is a monorepo to keep stuff organized.

+## Updating the CLI
+
+Because we release independently of `react-native`, it happens that you may be locked on a version without fixes for bugs that affect you. Here's how to get it sorted:
+
+1. If you use lock files (`yarn.lock` or `package-lock.json`) - find the `@react-native-community/cli` entry, remove it, run `yarn install` / `npm install` once again.
+2. If you don't use lock files – remove `node_modules` and run `yarn install` / `npm install` again.
+3. Run `yarn list @react-native-community/cli` or `npm list @react-native-community/cli` and verify you're on the latest version.
+
+After performing these steps you should be on the latest CLI version. Feel free to do it once in a while, because we release often.
