-
-## Scope
-

+## Getting started

-## Why use Docs ❓
+### Prerequisite

-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)
-
-### 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
-
-## Getting started 🔧
-
-### Test it
-
-Test Docs on your browser by logging in on this [environment](https://impress-preprod.beta.numerique.gouv.fr/)
-
-```
-email: test.docs@yopmail.com
-password: I'd<3ToTestDocs
-```
-
-### Run it locally
-
-> ⚠️ 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 but you can choose any S3 compatible object storage of your choice.
-
-**Prerequisite**
-
-Make sure you have a recent version of Docker and [Docker Compose](https://docs.docker.com/compose/install) installed on your laptop:
-
-```shellscript
+```bash
 $ docker -v
+  Docker version 20.10.2, build 2291f61

-Docker version 20.10.2, build 2291f61
-
-$ docker compose version
-
-Docker Compose version v2.32.4
+$ docker compose -v
+  docker compose version 1.27.4, build 40524192
 ```

-> ⚠️ 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**
+### Project bootstrap

-The easiest way to start working on the project is to use [GNU Make](https://www.gnu.org/software/make/):
+The easiest way to start working on the project is to use GNU Make:

-```shellscript
+```bash
 $ 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-related or migration-related issues.
-
-Your Docker services should now be up and running 🎉
-
-You can access to the project by going to <http://localhost:3000>.
-
+Then you can access to the project in development mode 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:

+Your Docker services should now be up and running 🎉
+
+Note that if you need to run them afterwards, you can use the eponym Make rule:
+
+```bash
+$ make run-frontend-dev
 ```

-⚠️ For the frontend developer, it is often better to run the frontend in development mode locally.
+### Adding content

-To do so, install the frontend dependencies with the following command:
-
-```shellscript
-$ make frontend-development-install
-```
-
-And run the frontend locally in development mode with the following command:
-
-```shellscript
-$ make run-frontend-development
-```
-
-To start all the services, except the frontend container, you can use the following command:
-
-```shellscript
-$ make run-backend
-```
-
-**Adding content**
 You can create a basic demo site by running:

-```shellscript
-$ make demo
-```
+    $ make demo

 Finally, you can check all available Make rules using:

-```shellscript
+```bash
 $ make help
 ```

-**Django admin**
+### Django admin

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

 You first need to create a superuser account:

-```shellscript
+```bash
 $ make superuser
 ```

-## 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)
-
-```

-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

-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).

-
-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

-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.
