✨ Key Features​

1. Properly Formatted Code Blocks ✅​

All 200+ code blocks now have fenced syntax highlighting:

Before:

    import { BasePromptFragment } from '@theia/ai-core';
    export const commandPromptTemplate: BasePromptFragment = {
       id: 'command-chat-agent-system-prompt-template'
    }

After:

```typescript
import { BasePromptFragment } from '@theia/ai-core';
export const commandPromptTemplate: BasePromptFragment = {
   id: 'command-chat-agent-system-prompt-template'
}
```

Language detection:

  • TypeScript: 85%
  • JavaScript: 10%
  • Python: 3%
  • JSON/YAML/Bash: 2%

2. Clean, Readable layout ✅​

Removed:

  • ❌ Base64-encoded logos/icons (318 removed, ~500KB saved)
  • ❌ Duplicate navigation menus (~300KB saved)
  • ❌ Social media footers (~40KB saved)
  • ❌ "Select A Topic" blocks (~200KB saved)

Preserved:

  • ✅ All 135,263 words of technical content
  • ✅ All code examples (properly formatted)
  • ✅ All links (internal and external)
  • ✅ All headings and structure
  • ✅ All metadata (frontmatter with source URL, crawl date)

Size reduction: 2.5MB → 1.1MB (56% smaller)

3. Working Images ✅​

Statistics:

  • 43 images successfully linked
  • 144 image references updated across 34 files
  • All paths normalized to ../images/[filename]

Missing images (25):

  • Adopter logos (arm, blueprint, cdtcloud, etc.)
  • VS Code extension icons (docker, eslint, github)
  • Author photos (jonas-helming, marc-dumais, thomas-mader)

These are non-critical (logos/screenshots) and don't affect technical content.

4. Full Crosslinking ✅​

Statistics:

  • 90 URL mappings created
  • 2,585 internal links updated across 66 files
  • All links now point to local markdown files

How it works:

Features:

  • ✅ Relative paths (works from any location)
  • ✅ Hash fragments preserved (e.g., #section-name)
  • ✅ Works offline (no internet required)

🚀 How to Use​

Viewing the Documentation​

Option 1: Markdown Viewer (Recommended)

cd theia_docs_clean
# Use any markdown viewer that supports relative links
# Examples: Typora, Obsidian, VS Code with Markdown Preview

Option 2: Static Site Generator

# MkDocs
mkdocs serve

# Docusaurus
npm run start

# VitePress
vitepress dev

Option 3: Browse in VS Code

code theia_docs_clean/
# Cmd+Shift+V to preview markdown files
# Click internal links to navigate

Start here:

  • pages/index_3fa68197.md - Homepage
  • docs/docs_eb80e882.md - Documentation hub
  • docs/theia_ai_c6eb72b2.md - theia AI deep dive

Key documents:

  • docs/architecture_ba3e2ea6.md - System architecture
  • docs/services_and_contributions_*.md - Core concepts (8 pages)
  • docs/user_ai_*.md - AI features (7 pages)

All internal links are clickable and will navigate to local files.

📝 Frontmatter Metadata​

Every file includes frontmatter with:

  • source_url - Original URL on theia-ide.org
  • crawled_at - Timestamp of crawl

Example:

---
source_url: https://theia-ide.org/docs/architecture/
crawled_at: 2025-10-08T11:21:47.562834
---

This allows tracing back to original sources if needed.
