 <img src="/docs/assets/docs_live_collaboration_light.gif" width="100%" align="center"/>
 
 ## Why use Docs ❓
 Docs is a collaborative text editor designed to address common challenges in knowledge building and sharing.
 
-### Write
-*   😌 Simple collaborative editing without the formatting complexity of markdown
-*   🔌 Offline? No problem, keep writing, your edits will get synced when back online
-*   💅 Create clean documents with limited but beautiful formatting options and focus on content
-*   🧱 Built for productivity (markdown support, many block types, slash commands, keyboard shortcuts).
-*   ✨ Save time thanks to our AI actions (generate, sum up, correct, translate)
+It offers a scalable and secure alternative to tools such as Google Docs, Notion (without the dbs), Outline, or Confluence.
 
-### Collaborate
-*   🤝 Collaborate in realtime with your team mates
-*   🔒 Granular access control to keep your information secure and shared with the right people
-*   📑 Professional document exports in multiple formats (.odt, .doc, .pdf) with customizable templates
-*   📚 Built-in wiki functionality to transform your team's collaborative work into organized knowledge `ETA 02/2025`
+### Write
+* 😌 Get simple, accessible online editing for your team.
+* 💅 Create clean documents with beautiful formatting options.
+* 🖌️ Focus on your content using either the in-line editor, or [the Markdown syntax](https://www.markdownguide.org/basic-syntax/).
+* 🧱 Quickly design your page thanks to the many block types, accessible from the `/` slash commands, as well as keyboard shortcuts.
+* 🔌 Write offline! Your edits will be synced once you're back online.
+* ✨ Save time thanks to our AI actions, such as rephrasing, summarizing, fixing typos, translating, etc. You can even turn your selected text into a prompt!
+
+### Work together
+* 🤝 Enjoy live editing! See your team collaborate in real time.
+* 🔒 Keep your information secure thanks to granular access control. Only share with the right people.
+* 📑 Export your content in multiple formats (`.odt`, `.docx`, `.pdf`) with customizable templates.
+* 📚 Turn your team's collaborative work into organized knowledge with Subpages.
 
 ### Self-host
-*   🚀 Easy to install, scalable and secure alternative to Notion, Outline or Confluence
+🚀 Docs is easy to install on your own servers
+
+Available methods: Helm chart, Nix package
+
+In the works: Docker Compose, YunoHost
+
+⚠️ For some advanced features (ex: Export as PDF) Docs relies on XL packages from BlockNote. These are licenced under AGPL-3.0 and are not MIT compatible. You can perfectly use Docs without these packages by setting the environment variable `PUBLISH_AS_MIT` to true. That way you'll build an image of the application without the features that are not MIT compatible. Read the [environment variables documentation](/docs/env.md) for more information.

 ## [Unreleased]
+
+## [3.3.0] - 2025-05-22
+
+⚠️ For some advanced features (ex: Export as PDF) Docs relies on XL packages from BlockNote. These are licenced under AGPL-3.0 and are not MIT compatible. You can perfectly use Docs without these packages by setting the environment variable `PUBLISH_AS_MIT` to true. That way you'll build an image of the application without the features that are not MIT compatible. Read the [environment variables documentation](/docs/docs/env.md) for more information.
+
+The footer is now configurable from a customization file. To override the default one, you can
+use the `THEME_CUSTOMIZATION_FILE_PATH` environment variable to point to your customization file.
+The customization file must be a JSON file and must follow the rules described in the
+[theming documentation](docs/theming.md).
+
+## [3.0.0] - 2025-03-28
+
+We are not using the nginx auth request anymore to access the collaboration server (`yProvider`)
+The authentication is now managed directly from the yProvider server. 
+You must remove the annotation `nginx.ingress.kubernetes.io/auth-url` from the `ingressCollaborationWS`.
+
+This means as well that the yProvider server must be able to access the Django server.
+To do so, you must set the `COLLABORATION_BACKEND_BASE_URL` environment variable to the `yProvider`
+service.
+
+## [2.2.0] - 2025-02-10
+
+- AI features are now limited to users who are authenticated. Before this release, even anonymous
+  users who gained editor access on a document with link reach used to get AI feature.
+  IF you want anonymous users to keep access on AI features, you must now define the
+  `AI_ALLOW_REACH_FROM` setting to "public".

+## 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 |

+## impress-frontend image
+
+These are the environment variables you can set to build the `impress-frontend` image.
+
+Depending on how you are building the front-end application, this variable is used in different ways.
+
+If you want to build the Docker image, this variable is used as an argument in the build command.
+
+Example:
+
+```
+docker build -f src/frontend/Dockerfile --target frontend-production --build-arg PUBLISH_AS_MIT=false docs-frontend:latest
+``` 
+
+If you want to build the front-end application using the yarn build command, you can edit the file `src/frontend/apps/impress/.env` with the `NODE_ENV=production` environment variable and modify it. Alternatively, you can use the listed environment variables with the prefix `NEXT_PUBLIC_` (for example, `NEXT_PUBLIC_PUBLISH_AS_MIT=false`).
+
+Example:
+
+```
+cd src/frontend/apps/impress
+NODE_ENV=production NEXT_PUBLIC_PUBLISH_AS_MIT=false yarn build
+```

+# 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.
+
+----
+
+# **Footer Configuration** 📝
+
+The footer is configurable from the theme customization file.
+
+### Settings 🔧
+
+```shellscript
+THEME_CUSTOMIZATION_FILE_PATH=<path>
+```
+
+### Example of JSON
+
+The json must follow some rules: https://github.com/suitenumerique/docs/blob/main/src/helm/env.d/dev/configuration/theme/demo.json
+
+`footer.default` is the fallback if the language is not supported.
+
