 # Quick Start
+
+## Setup Environment
+
+Before getting started, you will need to install [Node.js](https://nodejs.org/) >= version 16, it is recommended to use the Node.js LTS version.
+
+Check the current Node.js version with the following command:
+
+```bash
+node -v
+```
+
+If you do not have Node.js installed in current environment, or the installed version is too low, you can use [nvm](https://github.com/nvm-sh/nvm) or [fnm](https://github.com/Schniz/fnm) to install.
+
+Here is an example of how to install via nvm:
+
+```bash
+# Install Node.js LTS
+nvm install --lts
+# Switch to Node.js LTS
+nvm use --lts
+```
+
+## Creating an Rslib Project
+
+You can use the `create-rslib` to create a new Rslib project. Run the following command:
+
+import { PackageManagerTabs } from '@theme';
+
+<PackageManagerTabs
+  command={{
+    npm: 'npm create rslib@latest',
+    yarn: 'yarn create rslib',
+    pnpm: 'pnpm create rslib@latest',
+    bun: 'bun create rslib@latest',
+  }}
+/>
+
+Then follow the prompts to complete the operation.
+
+### Optional Tools
+
+`create-rslib` can help you set up some commonly used tools, including [Biome](https://github.com/biomejs/biome), [ESLint](https://github.com/eslint/eslint), and [prettier](https://github.com/prettier/prettier). You can use the arrow keys and the space bar to make your selections. If you don't need these tools, you can simply press Enter to skip.
+
+```text
+◆  Select additional tools (Use <space> to select, <enter> to continue)
+│  ◻ Add Biome for code linting and formatting
+│  ◻ Add ESLint for code linting
+│  ◻ Add Prettier for code formatting
+└
+```
+
+:::tip
+Biome provides similar linting and formatting features to ESLint and Prettier. If you select Biome, you typically won't need to choose ESLint or Prettier as well.
+:::
+
+### Current Directory
+
+If you need to create a project in the current directory, you can set the target folder to `.`:
+
+```text
+◆  Create Rslib Project
+│
+◇  Project name or path
+│  .
+│
+◇  "." is not empty, please choose:
+│  Continue and override files
+```
+
+### Quick Creation
+
+[create-rslib](https://www.npmjs.com/package/create-rslib) provides some CLI flags. By setting these CLI flags, you can skip the interactive selection steps and create the project with one command.
+
+For example, to create an example project in the `my-project` directory with one command:
+
+```bash
+npx create-rslib --dir my-project --template example
+
+# Using abbreviations
+npx create-rslib -d my-project -t example
+```
+
+All the CLI flags of `create-rslib`:
+
+```text
+Usage: create-rslib [options]
+
+Options:
+
+  -h, --help       display help for command
+  -d, --dir        create project in specified directory
+  -t, --template   specify the template to use
+  --tools          select additional tools (biome, eslint, prettier)
+  --override       override files in target directory
+```
