-### 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, markdown support, keyboard shortcuts) (page in french sorry 😅).
+*   ✨ 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/)
+```
+email: test.docs@yopmail.com
+password: I'd<3ToTestDocs
+```
+### 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
+  Docker version 27.4.1, build b9d17ea
 
-$ docker compose -v
-  docker compose version 1.27.4, build 40524192
+$ docker compose version
+  Docker Compose version v2.32.1
 ```
 
-> ⚠️ 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 assigning 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'
 ```
 
-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

+You can access to the project by going to <http://localhost:3000>.
 
-```bash

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

+

 ```
 
-### Adding content
+📝 Note that if you need to run them afterwards, you can use the eponym Make rule:
 
+```shellscript
+$ make run-with-frontend
+```
+
+⚠️ 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:
+
+```shellscript
+$ make frontend-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
+```
+
+**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
 ```
 
-### 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:
 
-```bash
+```shellscript
 $ make superuser
 ```

+# Installation with docker compose
+
+We provide a configuration for running Docs in production using docker compose. This configuration is experimental, the official way to deploy Docs in production is to use [k8s](docs/installation/k8s.md)
+
+## Requirements
+
+- A modern version of Docker and its Compose plugin.
+- SSL certificates for Docs domain and Keycloak.
+- Two domain name. One for the Docs application and an other one for Keycloak. Both can be a subdomain of a common domain. (example: docs.domain.tld and keycloak.domain.tld)
+
+## Installation
+
+- Clone this repository: `git clone https://github.com/suitenumerique/docs.git`
+- Then in the clone directory you can run the following command: `make bootsrap-production`
+
+## Configure your ssl certificates
+
+You have to provide the ssl certificates. The easiest way is to use [certbot](https://certbot.eff.org/), generate the certificates with it (both for Docs and Keycloak) and then mount them in ingress and keycloak containers. Two environment variables can be used for that: 
+- `DOCS_PROD_NGINX_CERT_FOLDER` path to the folder containing the certificates for Docs. This folder will be mounted in `/etc/nginx/ssl` in the container. You have to adapt the certificates name in the file `docker/files/production/etc/nginx/conf.d/default.conf` accordingly with the certificates name you have (see `ssl_certificate` and `ssl_certificate_key` directives).
+- `DOCS_PROD_KEYCLOAK_CERT_FOLDER` path to the folder containing the certificates for Keycloak. This folder will be mounted in `/etc/ssl/certs` in the container. You have to adapt the certificates name in the configuration file in `env.d/production/keycloak` to add the correct path for environment variables `KC_HTTPS_CERTIFICATE_FILE` and `KC_HTTPS_CERTIFICATE_KEY_FILE`.
+
+### Configuration
+
+All the configuration files are in the directory `env.d/production`. You have to edit all the files to complete them. For the OIDC information you will have them once Keycloak will be running and you have configured your own realm on it.
+
+#### env.d/production/minio
+
+All the settings related to Minio. You have to set a username and a password to manage the minio cluster. You will need them later in the `env.d/production/backend` file.
+
+#### env.d/production/postgresql
+
+All the settings related to the Postgresql database used by the Django application.
+
+#### env.d/production/yprovider
+
+All the settings related to the collaboration server. All the secret and api key must be generated.
+
+#### env.d/production/kc_postgresql
+
+All the settings related to the Postgresql database used by keycloak.
+
+#### env.d/production/keycloak
+
+All the settings related to the Keycloak application.
+
+#### env.d/production/backend
+
+All the settings related to the Django application. Only the settings you don't have for now are all the one related to OIDC. You will have them once the compose started and you can access to Keycloak.
+
+## Run the compose configuration
+
+The compose configuration can be run with the following command: `make run-production`. The first start can be a little bit long, lots of things are created. Once started you can check that everything is running with the following command: `COMPOSE_FILE=compose.production.yaml ./bin/compose ps`
+
+## Configure keycloak
+
+You have to create a new realm in your Keycloak and once created you have to create a new OIDC client in it. You will use this client to configure the OIDC part in `env.d/production/backend`. This is the last missing part to complete the Django application configuration.
+Once the client information set in `env.d/production/backend` you have to start the containers again by running the commande `make run-production`. The command will recreate the containers with the good configuration.
+
+### Helpers
+
+there is a helper script to control the `docker compose` command. You can export the variable `COMPOSE_FILE` with the compose filename (`export COMPOSE_FILE=compose.production.yaml`). After you can run `./bin/compose` to run the docker compose command line.
+
+Makefile commands available:
+- `make bootstrap-production`: create the configuration files in `env.d/production`, create the directories : `data/production`. Both directories must be backup, if you loose them you loose all the data related to the application.
+- `make run-production`: up the ingress containers. Will start all the containers needed in cascade.
+- `make stop-production`: stop all the containers.

+# 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)

+
+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

+```
+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 :
+
+```

+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/

+```
+
+## 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

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