+⚠️ **Note that Docs provides docs/pdf exporters by loading [two BlockNote packages](https://github.com/suitenumerique/docs/blob/main/src/frontend/apps/impress/package.json#L22C7-L23C53), which we use under the AGPL-3.0 licence.

+## Decision TLDR;
+
+We will use Yjs a CRDT-based library for the collaborative editing of the documents.
+
+## Status
+
+Accepted
+
+## Context
+
+We need to implement a collaborative editing feature for the documents that supports real-time collaboration, offline capabilities, and seamless integration with our Django backend.
+
+## Considered alternatives
+
+### ProseMirror
+
+A robust toolkit for building rich-text editors with collaboration capabilities.
+
+| Pros | Cons |
+| --- | --- |
+| Mature ecosystem | Complex integration with Django |
+| Rich text editing features | Steeper learning curve |
+| Used by major companies | More complex to implement offline support |
+| Large community | |
+
+### ShareDB
+
+Real-time database backend based on Operational Transformation.
+
+| Pros | Cons |
+| --- | --- |
+| Battle-tested in production | Complex setup required |
+| Strong consistency model | Requires specific backend architecture |
+| Good documentation | Less flexible with different backends |
+| | Higher latency compared to CRDTs |
+
+### Convergence
+
+Complete enterprise solution for real-time collaboration.
+
+| Pros | Cons |
+| --- | --- |
+| Full-featured solution | Commercial licensing |
+| Built-in presence features | Less community support |
+| Enterprise support | More expensive |
+| Good offline support | Overkill for basic needs |
+
+### CRDT-based Solutions Comparison
+
+A CRDT-based library specifically designed for real-time collaboration.
+
+| Category | Pros | Cons |
+|----------|------|------|
+| Technical Implementation | • Native real-time collaboration<br>• No central conflict resolution needed<br>• Works well with Django backend<br>• Automatic state synchronization | • Learning curve for CRDT concepts<br>• More complex initial setup<br>• Additional metadata overhead |
+| User Experience | • Instant local updates<br>• Works offline by default<br>• Low latency<br>• Smooth concurrent editing | • Eventual consistency might cause brief inconsistencies<br>• UI must handle temporary conflicts |
+| Performance | • Excellent scaling with multiple users<br>• Reduced server load<br>• Efficient network usage<br>• Good memory optimization (especially Yjs) | • Slightly higher memory usage<br>• Initial state sync can be larger |
+| Development | • No need to build conflict resolution<br>• Simple integration with text editors<br>• Future-proof architecture | • Team needs to learn new concepts<br>• Fewer ready-made solutions<br>• May need to build some features from scratch |
+| Maintenance | • Less server infrastructure<br>• Simpler deployment<br>• Fewer points of failure | • Debugging can be more complex<br>• State management requires careful handling |
+| Business Impact | • Better offline support for users<br>• Scales well as user base grows<br>• No licensing costs (with Yjs) | • Initial development time might be longer<br>• Team training required |
+
+#### Yjs
+- **Type**: State-based CRDT
+- **Implementation**: JavaScript/TypeScript
+- **Features**:
+  - Rich text collaboration
+  - Shared types (Array, Map, XML)
+  - Binary encoding
+  - P2P support
+- **Performance**: Excellent for text editing
+- **Memory Usage**: Optimized
+- **License**: MIT
+
+#### Automerge
+- **Type**: Operation-based CRDT
+- **Implementation**: JavaScript/Rust
+- **Features**:
+  - JSON-like data structures
+  - Change history
+  - Undo/Redo
+  - Binary format
+- **Performance**: Good, with Rust backend
+- **Memory Usage**: Higher than Yjs
+- **License**: MIT
+
+#### Legion
+- **Type**: State-based CRDT
+- **Implementation**: Rust with JS bindings
+- **Features**:
+  - High performance
+  - Memory efficient
+  - Binary protocol
+- **Performance**: Excellent
+- **Memory Usage**: Very efficient
+- **License**: Apache 2.0
+
+#### Diamond Types
+- **Type**: Operation-based CRDT
+- **Implementation**: TypeScript
+- **Features**:
+  - Specialized for text
+  - Small memory footprint
+  - Simple API
+- **Performance**: Good for text
+- **Memory Usage**: Efficient
+- **License**: MIT
+
+Comparison Table:
+
+| Feature | Yjs | Automerge | Legion | Diamond Types |
+|---------|-----|-----------|--------|---------------|
+| Text Editing | ✅ Excellent | ✅ Good | ⚠️ Basic | ✅ Excellent |
+| Structured Data | ✅ | ✅ | ✅ | ⚠️ |
+| Memory Efficiency | ✅ High | ⚠️ Medium | ✅ Very High | ✅ High |
+| Network Efficiency | ✅ | ⚠️ | ✅ | ✅ |
+| Maturity | ✅ | ✅ | ⚠️ | ⚠️ |
+| Community Size | ✅ Large | ✅ Large | ⚠️ Small | ⚠️ Small |
+| Documentation | ✅ | ✅ | ⚠️ | ⚠️ |
+| Backend Options | ✅ Many | ✅ Many | ⚠️ Limited | ⚠️ Limited |
+
+Key Differences:
+1. **Implementation Approach**:
+   - Yjs: Optimized for text and rich-text editing
+   - Automerge: General-purpose JSON CRDT
+   - Legion: Performance-focused with Rust
+   - Diamond Types: Specialized for text collaboration
+
+2. **Performance Characteristics**:
+   - Yjs: Best for text editing scenarios
+   - Automerge: Good all-around performance
+   - Legion: Excellent raw performance
+   - Diamond Types: Optimized for text
+
+3. **Ecosystem Integration**:
+   - Yjs: Wide range of integrations
+   - Automerge: Good JavaScript ecosystem
+   - Legion: Limited but growing
+   - Diamond Types: Focused on text editors
+
+This analysis reinforces our choice of Yjs for the CRDT-based option as it provides:
+- Best-in-class text editing performance
+- Mature ecosystem
+- Active community
+- Excellent documentation
+- Wide range of backend options
+
+## Decision
+
+After evaluating the alternatives, we choose Yjs for the following reasons:
+
+1. **Technical Fit:**
+- Native CRDT support ensures reliable collaboration
+- Excellent offline capabilities
+- Good performance characteristics
+- Flexible backend integration options
+
+2. **Project Requirements Match:**
+- Easy integration with our Django backend
+- Supports our core collaborative features
+- Manageable learning curve for the team
+
+3. **Community & Support:**
+- Active development
+- Growing community
+- Good documentation
+- Open source with MIT license
+
+### Comparison of Key Features:
+
+| Feature | Yjs (CRDT) | ProseMirror | ShareDB | Convergence |
+|---------|-----|-------------|----------|-------------|
+| Real-time Collaboration | ✅ | ✅ | ✅ | ✅ |
+| Offline Support | ✅ | ⚠️ | ⚠️ | ✅ |
+| Django Integration | Easy | Complex | Complex | Moderate |
+| Learning Curve | Medium | High | High | Medium |
+| Cost | Free | Free | Free | Paid |
+| Community Size | Growing | Large | Medium | Small |
+
+## Consequences
+
+### Positive
+- Simplified implementation of real-time collaboration
+- Good developer experience
+- Future-proof technology choice
+- No licensing costs
+
+### Negative
+- Team needs to learn CRDT concepts
+- Newer technology compared to alternatives
+- May need to build some features available out-of-the-box in other solutions
+
+### Risks
+- Community support might not grow as expected
+- May discover limitations as we scale

 Docs uses OIDC, so if you already have an OIDC provider, obtain the necessary information to use it. In the next step, we will see how to configure Django (and thus Docs) to use it. If you do not have a provider, we will show you how to deploy a local Keycloak instance (this is not a production deployment, just a demo).

+# Runtime Theming 🎨
+
+### How to Use
+
+To use this feature, simply set the `FRONTEND_CSS_URL` environment variable to the URL of your custom CSS file. For example:
+
+```javascript
+FRONTEND_CSS_URL=http://anything/custom-style.css
+```
+
+Once you've set this variable, our application will load your custom CSS file and apply the styles to our frontend application.
+
+### Benefits
+
+This feature provides several benefits, including:
+
+*   **Easy customization** 🔄: With this feature, you can easily customize the look and feel of our application without requiring any code changes.
+*   **Flexibility** 🌈: You can use any CSS styles you like to create a custom theme that meets your needs.
+*   **Runtime theming** ⏱️: This feature allows you to change the theme of our application at runtime, without requiring a restart or recompilation.
+
+### Example Use Case
+
+Let's say you want to change the background color of our application to a custom color. You can create a custom CSS file with the following contents:
+
+```css
+body {
+  background-color: #3498db;
+}
+```
+
+Then, set the `FRONTEND_CSS_URL` environment variable to the URL of your custom CSS file. Once you've done this, our application will load your custom CSS file and apply the styles, changing the background color to the custom color you specified.
