 UNOFFICIAL standard module for Scrapbox UserScript
+
+## Getting Started
+
+This library serves as an unofficial standard library for developing Scrapbox
+userscripts. It provides a comprehensive set of utilities for interacting with
+Scrapbox's features, including REST API operations, browser interactions, and
+common utilities.
+
+### Installation
+
+1. Bundler Configuration This library is distributed through JSR (JavaScript
+   Registry) and requires a bundler configuration. Follow these steps:
+
+a. Configure your bundler to use JSR:
+
+- For esbuild: Add JSR to your import map
+- For other bundlers: Refer to your bundler's JSR integration documentation
+
+b. Import the library:
+
+```typescript
+// Import commonly used functions
+import { getPage } from "jsr:@cosense/std/rest";
+import { parseAbsoluteLink } from "jsr:@cosense/std";
+
+// Import specific modules (recommended)
+import { getLinks } from "jsr:@cosense/std/rest";
+import { press } from "jsr:@cosense/std/browser/dom";
+import { getLines } from "jsr:@cosense/std/browser/dom";
+```
+
+2. Module Organization The library is organized into the following main modules:
+
+- `rest/`: API operations for Scrapbox REST endpoints
+  - Page operations
+  - Project management
+  - User authentication
+- `browser/`: Browser-side operations
+  - DOM manipulation
+  - WebSocket communication
+  - Event handling
+- Core utilities:
+  - `title`: Title parsing and formatting
+  - `parseAbsoluteLink`: External link analysis
+  - Additional helper functions
+
+## Examples
+
+### Basic Usage
+
+1. Retrieving Page Information
+
+```typescript
+// Get page content and metadata
+import { getPage } from "jsr:@cosense/std/rest";
+
+const result = await getPage("projectName", "pageName");
+if (result.ok) {
+  const page = result.val;
+  console.log("Page title:", page.title);
+  console.log("Page content:", page.lines.map((line) => line.text));
+  console.log("Page descriptions:", page.descriptions.join("\n"));
+}
+```
+
+2. DOM Operations
+
+```typescript
+// Interact with the current page's content
+import { getLines, press } from "jsr:@cosense/std/browser/dom";
+
+// Get all lines from the current page
+const lines = getLines();
+console.log(lines.map((line) => line.text));
+
+// Simulate keyboard input
+await press("Enter"); // Add a new line
+await press("Tab"); // Indent the line
+```
+
+3. External Link Analysis
+
+```typescript
+// Parse external links (YouTube, Spotify, etc.)
+import { parseAbsoluteLink } from "jsr:@cosense/std";
+import type { LinkNode } from "@progfay/scrapbox-parser";
+
+// Create a link node with absolute path type
+const link = {
+  type: "link" as const,
+  pathType: "absolute" as const,
+  href: "https://www.youtube.com/watch?v=xxxxx",
+  content: "",
+  raw: "[https://www.youtube.com/watch?v=xxxxx]",
+} satisfies LinkNode & { pathType: "absolute" };
+
+// Parse and handle different link types
+const parsed = parseAbsoluteLink(link);
+if (parsed?.type === "youtube") {
+  // Handle YouTube links
+  console.log("YouTube video ID:", parsed.href.split("v=")[1]);
+  const params = new URLSearchParams(parsed.href.split("?")[1]);
+  const start = params.get("t");
+  if (start) {
+    console.log("Video timestamp:", start);
+  }
+} else if (parsed?.type === "spotify") {
+  // Handle Spotify links
+  const match = parsed.href.match(/spotify\.com\/track\/([^?]+)/);
+  if (match) {
+    console.log("Spotify track ID:", match[1]);
+  }
+}
+```
+
+### Important Notes
+
+- This library requires a bundler for use in userscripts
+- Full TypeScript support with type definitions included
+- Comprehensive error handling with type-safe responses
+- For more examples and use cases, see the
+  [Examples](https://github.com/takker99/scrapbox-userscript-std/tree/main/examples)
+  directory
