+# 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.
+

-## Getting started
+<img src="/docs/assets/docs_live_collaboration_light.gif" width="100%" align="center"/>
 
-### Prerequisite
+## Why use Docs ❓
+Docs is a collaborative text editor designed to address common challenges in knowledge building and sharing.
 
-Make sure you have a recent version of Docker and [Docker
-Compose](https://docs.docker.com/compose/install) installed on your laptop:
+### 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)
 
-```bash
+### 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`
+
+### Self-host
+*   🚀 Easy to install, scalable and secure alternative to Notion, Outline or Confluence
+
+## Getting started 🔧
+### Test it
+Test Docs on your browser by logging in on this [environment](https://impress-preprod.beta.numerique.gouv.fr/docs/0aa856e9-da41-4d59-b73d-a61cb2c1245f/)
+```

+### Run it locally
+**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 version 20.10.2, build 2291f61

-> ⚠️ You may need to run the following commands with `sudo` but this can be
-> avoided by assigning your user to the `docker` group.
-
-### Project bootstrap
+> ⚠️ 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 can access to the project by going to <http://localhost:3000>.
+
 You will be prompted to log in, the default credentials are:
-```bash
+
+```
 username: impress
 password: impress
 ```
 
 📝 Note that if you need to run them afterwards, you can use the eponym Make rule:
 
-```bash
+```shellscript
 $ make run-with-frontend
 ```
 
----
+⚠️ 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
+```shellscript
 $ make frontend-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
+```shellscript
 $ make run
 ```

-### Adding content
-
+**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:
 
-```bash
+```shellscript
 $ make help
 ```

 You can access the Django admin site at
-[http://localhost:8071/admin](http://localhost:8071/admin).

+# Security Policy
+
+## Reporting a Vulnerability
+
+Security is very important to us.
+
+If you have any issue regarding security, please disclose the information responsibly submiting [this form](https://vdp.numerique.gouv.fr/p/Send-a-report?lang=en) and not by creating an issue on the repository. You can also email us at docs@numerique.gouv.fr
+
+We appreciate your effort to make Docs more secure.
+
+## 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.

+# Installation on a k8s cluster
+
+This document is a step-by-step guide that describes how to install Docs on a k8s cluster without AI features. It's a teaching document to learn how it's work. It needs to be adapt for production environment.
+
+
+## Prerequisites
+
+- k8s cluster with an nginx-ingress controller
+- an OIDC provider (if you don't have one, we will provide an example)
+- a PostgreSQL server (if you don't have one, we will provide an example)
+- a Memcached server (if you don't have one, we will provide an example)
+- a S3 bucket (if you don't have one, we will provide an example)
+
+### Test cluster
+
+If you do not have a test cluster, you can install everything on a local kind cluster. In this case, the simplest way is to use our script **bin/start-kind.sh**.
+
+To be able to use the script, you will need to install:
+
+- Docker (https://docs.docker.com/desktop/)
+- Kind (https://kind.sigs.k8s.io/docs/user/quick-start/#installation)
+- Mkcert (https://github.com/FiloSottile/mkcert#installation)
+- Helm (https://helm.sh/docs/intro/quickstart/#install-helm)
+
+```
+./bin/start-kind.sh

+0. Create ca
+The local CA is already installed in the system trust store! 👍
+The local CA is already installed in the Firefox and/or Chrome/Chromium trust store! 👍
+
+
+Created a new certificate valid for the following names 📜
+ - "127.0.0.1.nip.io"
+ - "*.127.0.0.1.nip.io"
+
+Reminder: X.509 wildcards only go one level deep, so this won't match a.b.127.0.0.1.nip.io ℹ️
+
+The certificate is at "./127.0.0.1.nip.io+1.pem" and the key at "./127.0.0.1.nip.io+1-key.pem" ✅
+
+It will expire on 24 March 2027 🗓
+
+1. Create registry container unless it already exists
+2. Create kind cluster with containerd registry config dir enabled
+Creating cluster "suite" ...
+ ✓ Ensuring node image (kindest/node:v1.27.3) 🖼
+ ✓ Preparing nodes 📦  
+ ✓ Writing configuration 📜 
+ ✓ Starting control-plane 🕹️ 
+ ✓ Installing CNI 🔌 
+ ✓ Installing StorageClass 💾 
+Set kubectl context to "kind-suite"
+You can now use your cluster with:
+
+kubectl cluster-info --context kind-suite
+
+Thanks for using kind! 😊
+3. Add the registry config to the nodes
+4. Connect the registry to the cluster network if not already connected
+5. Document the local registry
+configmap/local-registry-hosting created
+Warning: resource configmaps/coredns is missing the kubectl.kubernetes.io/last-applied-configuration annotation which is required by kubectl apply. kubectl apply should only be used on resources created declaratively by either kubectl create --save-config or kubectl apply. The missing annotation will be patched automatically.
+configmap/coredns configured
+deployment.apps/coredns restarted
+6. Install ingress-nginx
+namespace/ingress-nginx created
+serviceaccount/ingress-nginx created

+ingressclass.networking.k8s.io/nginx created
+validatingwebhookconfiguration.admissionregistration.k8s.io/ingress-nginx-admission created
+secret/mkcert created
+deployment.apps/ingress-nginx-controller patched
+7. Setup namespace
+namespace/impress created
+Context "kind-suite" modified.
+secret/mkcert created
+$ kubectl -n ingress-nginx get po
+NAME                                        READY   STATUS      RESTARTS   AGE
+ingress-nginx-admission-create-t55ph        0/1     Completed   0          2m56s
+ingress-nginx-admission-patch-94dvt         0/1     Completed   1          2m56s
+ingress-nginx-controller-57c548c4cd-2rx47   1/1     Running     0          2m56s
+```
+When your k8s cluster is ready (the ingress nginx controller is up), you can start the deployment. This cluster is special because it uses the *.127.0.0.1.nip.io domain and mkcert certificates to have full HTTPS support and easy domain name management.
+
+Please remember that *.127.0.0.1.nip.io will always resolve to 127.0.0.1, except in the k8s cluster where we configure CoreDNS to answer with the ingress-nginx service IP.
+
+## Preparation
+
+### What will you use to authenticate your users ?
+
+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).
+
+```
+$ kubectl create namespace impress
+$ kubectl config set-context --current --namespace=impress
+$ helm install keycloak oci://registry-1.docker.io/bitnamicharts/keycloak -f examples/keycloak.values.yaml
+$ #wait until
+$ kubectl get po
+NAME                    READY   STATUS    RESTARTS   AGE
+keycloak-0              1/1     Running   0          6m48s
+keycloak-postgresql-0   1/1     Running   0          6m48s
+```
+
+From here the important informations you will need are :
+
+```
+OIDC_OP_JWKS_ENDPOINT: https://keycloak.127.0.0.1.nip.io/realms/impress/protocol/openid-connect/certs
+OIDC_OP_AUTHORIZATION_ENDPOINT: https://keycloak.127.0.0.1.nip.io/realms/impress/protocol/openid-connect/auth
+OIDC_OP_TOKEN_ENDPOINT: https://keycloak.127.0.0.1.nip.io/realms/impress/protocol/openid-connect/token
+OIDC_OP_USER_ENDPOINT: https://keycloak.127.0.0.1.nip.io/realms/impress/protocol/openid-connect/userinfo
+OIDC_OP_LOGOUT_ENDPOINT: https://keycloak.127.0.0.1.nip.io/realms/impress/protocol/openid-connect/session/end
+OIDC_RP_CLIENT_ID: impress
+OIDC_RP_CLIENT_SECRET: ThisIsAnExampleKeyForDevPurposeOnly
+OIDC_RP_SIGN_ALGO: RS256
+OIDC_RP_SCOPES: "openid email"
+```
+
+You can find these values in **examples/keycloak.values.yaml**
+
+### Find redis server connexion values
+
+Impress need a redis so we will start by deploying a redis :
+
+```
+$ helm install redis oci://registry-1.docker.io/bitnamicharts/redis -f examples/redis.values.yaml
+$ kubectl get po
+NAME                    READY   STATUS    RESTARTS   AGE
+keycloak-0              1/1     Running   0          26m
+keycloak-postgresql-0   1/1     Running   0          26m
+redis-master-0          1/1     Running   0          35s
+```
+
+### Find postgresql connexion values
+
+Impress uses a postgresql db as backend so if you have a provider, obtain the necessary information to use it. If you do not have, you can install a postgresql testing environment as follow:
+
+```
+$ helm install postgresql oci://registry-1.docker.io/bitnamicharts/postgresql -f examples/postgresql.values.yaml
+$ kubectl get po
+NAME                    READY   STATUS    RESTARTS   AGE
+keycloak-0              1/1     Running   0          28m
+keycloak-postgresql-0   1/1     Running   0          28m
+postgresql-0            1/1     Running   0          14m
+redis-master-0          1/1     Running   0          42s
+```
+
+From here important informations you will need are :
+
+```
+DB_HOST: postgres-postgresql
+DB_NAME: impress
+DB_USER: dinum
+DB_PASSWORD: pass
+DB_PORT: 5432
+POSTGRES_DB: impress
+POSTGRES_USER: dinum
+POSTGRES_PASSWORD: pass
+```
+
+### Find s3 bucket connexion values
+
+Impress uses a s3 bucket to store documents so if you have a provider obtain the necessary information to use it. If you do not have, you can install a local minio testing environment as follow:
+
+```
+$ helm install minio oci://registry-1.docker.io/bitnamicharts/minio -f examples/minio.values.yaml
+$ kubectl get po
+NAME                       READY   STATUS      RESTARTS   AGE
+keycloak-0                 1/1     Running     0          38m
+keycloak-postgresql-0      1/1     Running     0          38m
+minio-84f5c66895-bbhsk     1/1     Running     0          42s
+minio-provisioning-2b5sq   0/1     Completed   0          42s
+postgresql-0               1/1     Running     0          24m
+redis-master-0             1/1     Running     0          10m
+```
+
+## Deployment
+
+Now you are ready to deploy Impress without AI. AI requiered more dependancies (openai API). To deploy impress you need to provide all previous informations to the helm chart.
+
+```
+$ helm repo add impress https://suitenumerique.github.io/docs/
+$ helm repo update
+$ helm install impress impress/docs -f examples/impress.values.yaml
+$ kubectl get po

+```
+
+## Test your deployment
+
+In order to test your deployment you have to login to your instance. If you use exclusively our examples you can do :
+
+```
+$ kubectl get ingress
+NAME                             CLASS    HOSTS                       ADDRESS     PORTS     AGE

+```
+
+You can use impress on https://impress.127.0.0.1.nip.io. The provisionning user in keycloak is impress/impress.
