+# Contributor Covenant Code of Conduct
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our community a harassment-free experience for everyone, regardless of age, body size, visible or invisible disability, ethnicity, sex characteristics, gender identity and expression, level of experience, education, socio-economic status, nationality, personal appearance, race, caste, color, religion, or sexual identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming, diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our community include:
+
+- Demonstrating empathy and kindness toward other people
+- Being respectful of differing opinions, viewpoints, and experiences
+- Giving and gracefully accepting constructive feedback
+- Accepting responsibility and apologizing to those affected by our mistakes, and learning from the experience
+- Focusing on what is best not just for us as individuals, but for the overall community
+
+Examples of unacceptable behavior include:
+
+- The use of sexualized language or imagery, and sexual attention or advances of any kind
+- Trolling, insulting or derogatory comments, and personal or political attacks
+- Public or private harassment
+- Publishing others' private information, such as a physical or email address, without their explicit permission
+- Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Enforcement Responsibilities
+
+- Community leaders are responsible for clarifying and enforcing our standards of acceptable behavior and will take appropriate and fair corrective action in response to any behavior that they deem inappropriate, threatening, offensive, or harmful.
+- Community leaders have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, and will communicate reasons for moderation decisions when appropriate.
+
+## Scope
+
+- This Code of Conduct applies within all community spaces, and also applies when an individual is officially representing the community in public spaces. Examples of representing our community include using an official e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event.
+
+## Enforcement
+
+- Instances of abusive, harassing, or otherwise unacceptable behavior may be reported to the community leaders responsible for enforcement at docs@numerique.gouv.fr.
+
+- All complaints will be reviewed and investigated promptly and fairly.
+
+- All community leaders are obligated to respect the privacy and security of the reporter of any incident.
+
+## Enforcement Guidelines
+
+- Community leaders will follow these Community Impact Guidelines in determining the consequences for any action they deem in violation of this 
+
+## Code of Conduct:
+
+1. Correction
+
+Community Impact: Use of inappropriate language or other behavior deemed unprofessional or unwelcome in the community.
+
+Consequence: A private, written warning from community leaders, providing clarity around the nature of the violation and an explanation of why the behavior was inappropriate. A public apology may be requested.
+2. Warning
+
+Community Impact: A violation through a single incident or series of actions.
+
+Consequence: A warning with consequences for continued behavior. No interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, for a specified period of time. This includes avoiding interactions in community spaces as well as external channels like social media. Violating these terms may lead to a temporary or permanent ban.
+3. Temporary Ban
+
+Community Impact: A serious violation of community standards, including sustained inappropriate behavior.
+
+Consequence: A temporary ban from any sort of interaction or public communication with the community for a specified period of time. No public or private interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, is allowed during this period. Violating these terms may lead to a permanent ban.
+4. Permanent Ban
+
+Community Impact: Demonstrating a pattern of violation of community standards, including sustained inappropriate behavior, harassment of an individual, or aggression toward or disparagement of classes of individuals.
+
+Consequence: A permanent ban from any sort of public interaction within the community.
+Attribution
+
+This Code of Conduct is adapted from the Contributor Covenant, version 2.1, available at https://www.contributor-covenant.org/version/2/1/code_of_conduct.html.
+
+Community Impact Guidelines were inspired by Mozilla's code of conduct enforcement ladder.
+
+For answers to common questions about this code of conduct, see the FAQ at https://www.contributor-covenant.org/faq. Translations are available at https://www.contributor-covenant.org/translations.

+*   🔌 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)
 
-$ docker compose -v
-  docker compose version 1.27.4, build 40524192
+### Collaborate
+*   🤝 Collaborate with your team in real time
+*   🔒 Granular access control to ensure your information is secure and only shared with the right people
+*   📑 Professional document exports in multiple formats (.odt, .doc, .pdf) with customizable templates
+*   📚 Built-in wiki functionality to turn your team's collaborative work into organized knowledge `ETA 02/2025`
+
+### Self-host
+*   🚀 Easy to install, scalable and secure alternative to Notion, Outline or Confluence

+> ⚠️ Running Docs locally using the methods described below is for testing purposes only.  It is based on building Docs using Minio as the S3 storage solution: if you want to use Minio for production deployment of Docs, you will need to comply with Minio's AGPL-3.0 licence.
+
+**Prerequisite**
+
+Make sure you have a recent version of Docker and [Docker Compose](https://docs.docker.com/compose/install) installed on your laptop:
+
+```shellscript
+$ docker -v
+

+
+Docker Compose version v2.32.4
+```
+
+> ⚠️ You may need to run the following commands with sudo but this can be avoided by adding your user to the `docker` group.
+
+**Project bootstrap**
 
 The easiest way to start working on the project is to use GNU Make:
 
-```bash
+```shellscript
 $ make bootstrap FLUSH_ARGS='--no-input'
 ```
 
-This command builds the `app` container, installs dependencies, performs
-database migrations and compile translations. It's a good idea to use this
-command each time you are pulling code from the project repository to avoid
-dependency-releated or migration-releated issues.

+
 You will be prompted to log in, the default credentials are:

 ```
 
 📝 Note that if you need to run them afterwards, you can use the eponym Make rule:
 
-```bash
-$ make run-with-frontend
+```shellscript
+$ make run
 ```
 
----
+⚠️ For the frontend developer, it is often better to run the frontend in development mode locally.
 
-⚠️ For the frontend developper, it is often better to run the frontend in development mode locally. 
 To do so, install the frontend dependencies with the following command:
 
-```bash
-$ make frontend-install
+```shellscript
+$ make frontend-development-install
 ```
+
 And run the frontend locally in development mode with the following command:
 
-```bash
+```shellscript
 $ make run-frontend-development
 ```
 
 To start all the services, except the frontend container, you can use the following command:
 
-```bash
-$ make run
+```shellscript
+$ make run-backend
 ```

+**Adding content**
 You can create a basic demo site by running:
 
-    $ make demo
+```shellscript
+$ make demo
+```
 
 Finally, you can check all available Make rules using:

+## Vulnerability disclosure policy
+
+Working with security issues in an open source project can be challenging, as we are required to disclose potential problems that could be exploited by attackers. With this in mind, our security fix policy is as follows:
+
+1. The Maintainers team will handle the fix as usual (Pull Request,
+release).
+2. In the release notes, we will include the identification numbers from the
+GitHub Advisory Database (GHSA) and, if applicable, the Common Vulnerabilities
+and Exposures (CVE) identifier for the vulnerability.
+3. Once this grace period has passed, we will publish the vulnerability.
+
+By adhering to this security policy, we aim to address security concerns
+effectively and responsibly in our open source software project.

+        - Ascending: GET /api/v1.0/documents/?ordering=created_at
+        - Desceding: GET /api/v1.0/documents/?ordering=-title
+
+    ### Filtering:
         - `is_creator_me=true`: Returns documents created by the current user.
         - `is_creator_me=false`: Returns documents created by other users.
         - `is_favorite=true`: Returns documents marked as favorite by the current user
         - `is_favorite=false`: Returns documents not marked as favorite by the current user
         - `title=hello`: Returns documents which title contains the "hello" string
 
-    Example Usage:
+        Example:
         - GET /api/v1.0/documents/?is_creator_me=true&is_favorite=true
         - GET /api/v1.0/documents/?is_creator_me=false&title=hello
+
+    ### Annotations:
+    1. **is_favorite**: Indicates whether the document is marked as favorite by the current user.
+    2. **user_roles**: Roles the current user has on the document or its ancestors.
+
+    ### Notes:
+    - Only the highest ancestor in a document hierarchy is shown in list views.
+    - Implements soft delete logic to retain document tree structures.
