-# Configuring `mddb.config.js`
+# Configuring `markdowndb.config.js`
 
-## Overview
-
-`mddb.config.js` allows you to tailor the behavior of MarkdownDB by providing various configuration options. This section outlines the available options and how to use them.
-
-### 1. Integration of Configuration Options
-
-Integrate a configuration file (`mddb.config.js`) to enhance customization options for MarkdownDB.
-
-### 2. Computed Fields
-
-Implement computed fields to dynamically calculate values based on specified logic or dependencies.
-
-### 3. File Inclusion/Exclusion Patterns
-
-MarkdownDB supports configuring include and exclude file glob patterns, providing flexibility similar to the approach used in Next.js/TypeScript.
-
-### 4. Initializing Configuration Using CLI
-
-To initialize the MarkdownDB configuration file, use the following CLI command:
-
-```bash
-npx markdowndb init
-```
-
-## `mddb.config.js` Structure
-
-```javascript
-// mddb.config.js
-
-export interface CustomConfig {
-  customFields?: ((fileInfo: FileInfo, ast: Root) => any)[];
-  include?: string[];
-  exclude?: string[];
-}
-```

-Feel free to customize the configuration based on your project requirements.
