+# Redis Commands
+
+This module exports all the commands that Redis supports.
+
+## Install
+
+```shell
+$ npm install @ioredis/commands
+```
+
+## Usage
+
+```js
+const commands = require('@ioredis/commands');
+```
+
+`.list` is an array contains all the lowercased commands:
+
+```js
+commands.list.forEach((command) => {
+  console.log(command);
+});
+```
+
+`.exists()` is used to check if the command exists:
+
+```js
+commands.exists('set') // true
+commands.exists('other-command') // false
+```
+
+`.hasFlag()` is used to check if the command has the flag:
+
+```js
+commands.hasFlag('set', 'readonly') // false
+```
+
+`.getKeyIndexes()` is used to get the indexes of keys in the command arguments:
+
+```js
+commands.getKeyIndexes('set', ['key', 'value']) // [0]
+commands.getKeyIndexes('mget', ['key1', 'key2']) // [0, 1]
+```
