-⚠️ For the PDF and Docx export Docs relies on XL packages from BlockNote licenced in AGPL-3.0. Please make sure you fulfill your obligations regarding BlockNote licensing (see https://github.com/TypeCellOS/BlockNote/blob/main/packages/xl-pdf-exporter/LICENSE and https://www.blocknotejs.org/about#partner-with-us).
+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.

 ## 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
+```
+

+* `xl-pdf-exporter`: [AGPL-3.0](https://github.com/TypeCellOS/BlockNote/blob/main/packages/xl-pdf-exporter/LICENSE) 
+
+In `.env.development`, `PUBLISH_AS_MIT` is set to `false`, allowing developers to test Docs with all its features.
+
+⚠️ If you run Docs in production with `PUBLISH_AS_MIT` set to `false` make sure you fulfill your [BlockNote licensing](https://github.com/TypeCellOS/BlockNote/blob/main/packages/xl-pdf-exporter/LICENSE) or [subscription](https://www.blocknotejs.org/about#partner-with-us) obligations.

+# Deploy and Configure Keycloak for Docs
+
+## Installation
+
+> \[!CAUTION\]
+> We provide those instructions as an example, for production environments, you should follow the [official documentation](https://www.keycloak.org/documentation).
+
+### Step 1: Prepare your working environment:
+
+```bash
+mkdir keycloak
+curl -o compose.yaml https://raw.githubusercontent.com/suitenumerique/docs/refs/heads/main/docs/examples/compose/keycloak/compose.yaml
+curl -o env.d/kc_postgresql https://raw.githubusercontent.com/suitenumerique/docs/refs/heads/main/env.d/production.dist/kc_postgresql
+curl -o env.d/keycloak https://raw.githubusercontent.com/suitenumerique/docs/refs/heads/main/env.d/production.dist/keycloak
+```
+
+### Step 2:. Update `env.d/` files
+
+The following variables need to be updated with your own values, others can be left as is:
+
+```env
+POSTGRES_PASSWORD=<generate postgres password>
+KC_HOSTNAME=https://id.yourdomain.tld # Change with your own URL
+KC_BOOTSTRAP_ADMIN_PASSWORD=<generate your password>
+```
+
+### Step 3: Expose keycloak instance on https
+
+> \[!NOTE\]
+> You can skip this section if you already have your own setup.
+
+To access your Keycloak instance on the public network, it needs to be exposed on a domain with SSL termination. You can use our [example with nginx proxy and Let's Encrypt companion](../nginx-proxy/README.md) for automated creation/renewal of certificates using [acme.sh](http://acme.sh).
+
+If following our example, uncomment the environment and network sections in compose file and update it with your values.
+
+```yaml
+version: '3'
+services:
+  keycloak:
+   ...
+    # Uncomment and set your values if using our nginx proxy example
+    # environment:
+    # - VIRTUAL_HOST=id.yourdomain.tld # used by nginx proxy 
+    # - VIRTUAL_PORT=8080 # used by nginx proxy
+    # - LETSENCRYPT_HOST=id.yourdomain.tld # used by lets encrypt to generate TLS certificate
+   ...
+# Uncomment if using our nginx proxy example
+#    networks:
+#    - proxy-tier
+#    - default
+
+# Uncomment if using our nginx proxy example
+#networks:
+#  proxy-tier:
+#    external: true
+```
+
+### Step 4: Start the service
+
+```bash
+`docker compose up -d`
+```
+
+Your keycloak instance is now available on https://doc.yourdomain.tld
+
+## Creating an OIDC Client for Docs Application
+
+### Step 1: Create a New Realm
+
+1. Log in to the Keycloak administration console.
+2. Navigate to the realm tab and click on the "Create realm" button.
+3. Enter the name of the realm  - `docs`.
+4. Click "Create".
+
+#### Step 2: Create a New Client
+
+1. Navigate to the "Clients" tab.
+2. Click on the "Create client" button.
+3. Enter the client ID - e.g. `docs`.
+4. Enable "Client authentication" option.
+6. Set the "Valid redirect URIs" to the URL of your docs application suffixed with `/*` - e.g., "https://docs.example.com/*".
+1. Set the "Web Origins" to the URL of your docs application - e.g. `https://docs.example.com`.
+1. Click "Save".
+
+#### Step 3: Get Client Credentials
+
+1. Go to the "Credentials" tab.
+2. Copy the client ID (`docs` in this example) and the client secret.

+# Deploy and Configure Minio for Docs
+
+## Installation
+
+> \[!CAUTION\]
+> We provide those instructions as an example, it should not be run in production. For production environments, deploy MinIO [in a Multi-Node Multi-Drive (Distributed)](https://min.io/docs/minio/linux/operations/install-deploy-manage/deploy-minio-multi-node-multi-drive.html#minio-mnmd) topology
+
+### Step 1: Prepare your working environment:
+
+```bash
+mkdir minio
+curl -o compose.yaml https://raw.githubusercontent.com/suitenumerique/docs/refs/heads/main/docs/examples/compose/minio/compose.yaml 
+```
+
+### Step 2:. Update compose file with your own values
+
+```yaml
+version: '3'
+services:
+  minio:
+   ...
+    environment:
+    - MINIO_ROOT_USER=<Set minio root username>
+    - MINIO_ROOT_PASSWORD=<Set minio root password>
+```
+
+### Step 3: Expose MinIO instance
+
+#### Option 1: Internal network
+
+You may not need to expose your MinIO instance to the public if only services hosted on the same private network need to access to your MinIO instance.
+
+You should create a docker network that will be shared between those services
+
+```bash
+docker network create storage-tier
+```
+
+#### Option 2: Public network
+
+If you want to expose your MinIO instance to the public, it needs to be exposed on a domain with SSL termination. You can use our [example](../nginx-proxy/README.md) with an nginx proxy and Let's Encrypt companion for automated creation/renewal of Let's Encrypt certificates using [acme.sh](http://acme.sh).
+
+If following our example, uncomment the environment and network sections in compose file and update it with your values.
+
+```yaml
+version: '3'
+services:
+   docs:
+   ...
+  minio:
+   ...
+    environment:
+   ...
+    # - VIRTUAL_HOST=storage.yourdomain.tld # used by nginx proxy 
+    # - VIRTUAL_PORT=9000 # used by nginx proxy
+    # - LETSENCRYPT_HOST=storage.yourdomain.tld # used by lets encrypt to generate TLS certificate
+   ...
+# Uncomment if using our nginx proxy example
+#    networks:
+#    - proxy-tier
+#    - default
+
+# Uncomment if using our nginx proxy example
+#networks:
+#  proxy-tier:
+#    external: true
+```
+
+In this example we are only exposing MinIO API service. Follow the official documentation to configure Minio WebUI.
+
+### Step 4: Start the service
+
+```bash
+`docker compose up -d`
+```
+
+Your minio instance is now available on https://storage.yourdomain.tld

+## Creating a user and bucket for your Docs instance
+
+### Installing mc
+
+Follow the [official documentation](https://min.io/docs/minio/linux/reference/minio-mc.html#install-mc) to install mc
+
+### Step 1: Configure `mc` to connect to your MinIO Server with your root user
+
+```shellscript
+mc alias set minio <MINIO_SERVER_URL> <MINIO_ROOT_USER> <MINIO_ROOT_PASSWORD>
+```
+
+Replace the values with those you have set in the previous steps
+
+### Step 2: Create a new bucket with versioning enabled
+
+```shellscript
+mc mb --with-versioning minio/<your-bucket-name>
+```
+
+Replace `your-bucket-name` with the desired name for your bucket e.g. `docs-media-storage`
+
+### Additional notes:
+
+For increased security you should create a dedicated user with `readwrite` access to the Bucket. In the following example we will use MinIO root user.

+# Nginx proxy with automatic SSL certificates
+
+> \[!CAUTION\]
+> We provide those instructions as an example, for extended development or production environments, you should follow the [official documentation](https://github.com/nginx-proxy/acme-companion/tree/main/docs).
+
+Nginx-proxy sets up a container running nginx and docker-gen. docker-gen generates reverse proxy configs for nginx and reloads nginx when containers are started and stopped.
+
+Acme-companion is a lightweight companion container for nginx-proxy. It handles the automated creation, renewal and use of SSL certificates for proxied Docker containers through the ACME protocol.
+
+## Installation
+
+### Step 1: Prepare your working environment:
+
+```bash
+mkdir nginx-proxy
+curl -o compose.yaml https://raw.githubusercontent.com/suitenumerique/docs/refs/heads/main/docs/examples/compose/nginx-proxy/compose.yaml
+```
+
+### Step 2: Edit `DEFAULT_EMAIL` in the compose file.
+
+Albeit optional, it is recommended to provide a valid default email address through the `DEFAULT_EMAIL` environment variable, so that Let's Encrypt can warn you about expiring certificates and allow you to recover your account.
+
+### Step 3: Create docker network
+
+Containers need share the same network for auto-discovery.
+
+```bash
+docker network create proxy-tier
+```
+
+### Step 4: Start service
+
+```bash
+docker compose up -d
+```
+
+## Usage
+
+Once both nginx-proxy and acme-companion containers are up and running, start any container you want proxied with environment variables `VIRTUAL_HOST` and `LETSENCRYPT_HOST` both set to the domain(s) your proxied container is going to use.

+# Installation with docker compose
+
+We provide a sample configuration for running Docs using Docker Compose. Please note that this configuration is experimental, and the official way to deploy Docs in production is to use [k8s](../installation/k8s.md)
+
+## Requirements
+
+- A modern version of Docker and its Compose plugin.
+- A domain name and DNS configured to your server.
+- An Identity Provider that supports OpenID Connect protocol - we provide [an example to deploy Keycloak](../examples/compose/keycloak/README.md).
+- An Object Storage that implements S3 API - we provide [an example to deploy Minio](../examples/compose/minio/README.md).
+- A Postgresql database - we provide [an example in the compose file](../examples/compose/compose.yaml).
+- A Redis database - we provide [an example in the compose file](../examples/compose/compose.yaml).
+
+## Software Requirements
+
+Ensure you have Docker Compose(v2) installed on your host server. Follow the official guidelines for a reliable setup:
+
+Docker Compose is included with Docker Engine:
+
+- **Docker Engine:** We suggest adhering to the instructions provided by Docker
+  for [installing Docker Engine](https://docs.docker.com/engine/install/).
+
+For older versions of Docker Engine that do not include Docker Compose:
+
+- **Docker Compose:** Install it as per the [official documentation](https://docs.docker.com/compose/install/).
+
+> [!NOTE]
+> `docker-compose` may not be supported. You are advised to use `docker compose` instead.
+
+## Step 1: Prepare your working environment:
+
+```bash
+mkdir -p docs/env.d
+curl -o compose.yaml https://raw.githubusercontent.com/suitenumerique/docs/refs/heads/main/docs/examples/compose/compose.yaml
+curl -o env.d/common https://raw.githubusercontent.com/suitenumerique/docs/refs/heads/main/env.d/production.dist/common
+curl -o env.d/backend https://raw.githubusercontent.com/suitenumerique/docs/refs/heads/main/env.d/production.dist/backend
+curl -o env.d/yprovider https://raw.githubusercontent.com/suitenumerique/docs/refs/heads/main/env.d/production.dist/yprovider
+curl -o env.d/common https://raw.githubusercontent.com/suitenumerique/docs/refs/heads/main/env.d/production.dist/postgresql
+```
+
+## Step 2: Configuration
+
+Docs configuration is achieved through environment variables. We provide a [detailed description of all variables](../env.md).
+
+In this example, we assume the following services:
+
+- OIDC provider on https://id.yourdomain.tld
+- Object Storage on https://storage.yourdomain.tld
+- Docs on https://docs.yourdomain.tld
+- Bucket name is docs-media-storage
+
+**Set your own values in `env.d/common`**
+
+### OIDC
+
+Authentication in Docs is managed through Open ID Connect protocol. A functional Identity Provider implementing this protocol is required.
+
+For guidance, refer to our [Keycloak deployment example](../examples/compose/keycloak/README.md).
+
+If using Keycloak as your Identity Provider, set `OIDC_RP_CLIENT_ID` and `OIDC_RP_CLIENT_SECRET` variables with those of the OIDC client created for Docs. By default we have set `docs` as the realm name, if you have named your realm differently, update the value `REALM_NAME` in `env.d/common`
+
+For others OIDC providers, update the variables in `env.d/backend`.
+
+### Object Storage
+
+Files and media are stored in an Object Store that supports the S3 API.
+
+For guidance, refer to our [Minio deployment example](../examples/compose/minio/README.md).
+
+Set `AWS_S3_ACCESS_KEY_ID` and `AWS_S3_SECRET_ACCESS_KEY` with the credentials of a user with `readwrite` access to the bucket created for Docs.
+
+### Postgresql
+
+Docs uses PostgreSQL as its database. Although an external PostgreSQL can be used, our example provides a deployment method.
+
+If you are using the example provided, you need to generate a secure key for `DB_PASSWORD` and set it in `env.d/postgresql`. 
+
+If you are using an external service or not using our default values, you should update the variables in `env.d/postgresql`
+
+### Redis
+
+Docs uses Redis for caching. While an external Redis can be used, our example provides a deployment method.
+
+If you are using an external service, you need to set `REDIS_URL` environment variable in `env.d/backend`.
+
+### Y Provider
+
+The Y provider service enables collaboration through websockets.
+
+Generates a secure key for `Y_PROVIDER_API_KEY` and `COLLABORATION_SERVER_SECRET` in ``env.d/yprovider``. 
+
+### Docs
+
+The Docs backend is built on the Django Framework.
+
+Generates a secure key for `DJANGO_SECRET_KEY` in `env.d/backend`. 
+
+### Logging
+
+Update the following variables in `env.d/backend` if you want to change the logging levels:
+```env
+LOGGING_LEVEL_HANDLERS_CONSOLE=DEBUG
+LOGGING_LEVEL_LOGGERS_ROOT=DEBUG
+LOGGING_LEVEL_LOGGERS_APP=DEBUG
+```
+
+### Mail
+
+The following environment variables are required in `env.d/backend` for the mail service to send invitations :
+
+```env
+DJANGO_EMAIL_HOST=<smtp host> 
+DJANGO_EMAIL_HOST_USER=<smtp user> 
+DJANGO_EMAIL_HOST_PASSWORD=<smtp password>
+DJANGO_EMAIL_PORT=<smtp port> 
+DJANGO_EMAIL_FROM=<your email address>
+
+#DJANGO_EMAIL_USE_TLS=true # A flag to enable or disable TLS for email sending.
+#DJANGO_EMAIL_USE_SSL=true # A flag to enable or disable SSL for email sending.
+
+
+DJANGO_EMAIL_BRAND_NAME=<brand name used in email templates> # e.g. "La Suite Numérique"
+DJANGO_EMAIL_LOGO_IMG=<logo image to use in email templates.> # e.g. "https://docs.yourdomain.tld/assets/logo-suite-numerique.png" 
+```
+
+### AI
+
+Built-in AI actions let users generate, summarize, translate, and correct content.
+
+AI is disabled by default. To enable it, the following environment variables must be set in in `env.d/backend`:
+
+```env
+AI_FEATURE_ENABLED=true # is false by default
+AI_BASE_URL=https://openaiendpoint.com
+AI_API_KEY=<API key>
+AI_MODEL=<model used> e.g. llama
+```
+
+### Frontend theme
+
+You can [customize your Docs instance](../theming.md) with your own theme and custom css.
+
+The following environment variables must be set in `env.d/backend`:
+
+```env
+FRONTEND_THEME=default # name of your theme built with cuningham
+FRONTEND_CSS_URL=https://storage.yourdomain.tld/themes/custom.css # custom css
+```
+
+## Step 3: Reverse proxy and SSL/TLS
+
+> [!WARNING]
+> In a production environment, configure SSL/TLS termination to run your instance on https.
+
+If you have your own certificates and proxy setup, you can skip this part.
+
+You can follow our [nginx proxy example](../examples/compose/nginx-proxy/README.md) with automatic generation and renewal of certificate with Let's Encrypt. 
+
+You will need to uncomment the environment and network sections in compose file and update it with your values.
+
+```yaml
+  frontend:
+    ...
+    # Uncomment and set your values if using our nginx proxy example
+    #environment:
+    # - VIRTUAL_HOST=${DOCS_HOST} # used by nginx proxy 
+    # - VIRTUAL_PORT=8083 # used by nginx proxy
+    # - LETSENCRYPT_HOST=${DOCS_HOST} # used by lets encrypt to generate TLS certificate
+    ...
+# Uncomment if using our nginx proxy example
+#    networks:
+#    - proxy-tier
+#
+#networks:
+#  proxy-tier:
+#    external: true
+```
+
+## Step 4: Start Docs
+
+You are ready to start your Docs application !
+
+```bash
+docker compose up -d
+```
+> [!NOTE]
+> Version of the images are set to latest, you should pin it to the desired version to avoid unwanted upgrades when pulling latest image.
+
+## Step 5: Run the database migration and create Django admin user
+
+```bash
+docker compose run --rm backend python manage.py migrate
+docker compose run --rm backend python manage.py createsuperuser --email <admin email> --password <admin password>
+```
+
+Replace `<admin email>` with the email of your admin user and generate a secure password. 
+
+Your docs instance is now available on the domain you defined, https://docs.yourdomain.tld.
+
+THe admin interface is available on https://docs.yourdomain.tld/admin with the admin user you just created.
+
+## How to upgrade your Docs application
+
+Before running an upgrade you must check the [Upgrade document](../../UPGRADE.md) for specific procedures that might be needed.
+
+You can also check the [Changelog](../../CHANGELOG.md) for brief summary of the changes.
+
+### Step 1: Edit the images tag with the desired version
+
+### Step 2: Pull the images
+
+```bash
+docker compose pull
+```
+
+### Step 3: Restart your containers
+
+```bash
+docker compose restart
+```
+
+### Step 4: Run the database migration
+Your database schema may need to be updated, run:
+```bash
+docker compose run --rm backend python manage.py migrate
+```

+## 3. Production Environment Memory Requirements
+
+Production deployments differ significantly from development environments. The table below shows typical memory usage for production services:
+
+| Service                  | Typical use                   | Rationale / notes                                                                       |
+| ------------------------ | ----------------------------- | --------------------------------------------------------------------------------------- |
+| PostgreSQL               | **2 – 8 GB**                 | Higher `shared_buffers` and connection pooling for concurrent users                    |
+| OIDC Provider (optional) | **Variable**                  | Any OIDC-compatible provider (Keycloak, Auth0, Azure AD, etc.) - external or self-hosted |
+| Redis                    | **256 MB – 2 GB**             | Session storage and caching; scales with active user sessions                          |
+| Object Storage (optional)| **External or self-hosted**   | Can use AWS S3, Azure Blob, Google Cloud Storage, or self-hosted MinIO               |
+| Django API (+ Celery)    | **1 – 3 GB**                 | Production workloads with background tasks and higher concurrency                      |
+| Static Files (Nginx)     | **< 200 MB**                 | Serves Next.js build output and static assets; no development overhead                |
+| Y-Provider (y-websocket) | **200 MB – 1 GB**             | Scales with concurrent document editing sessions                                        |
+| Nginx (Load Balancer)    | **< 200 MB**                  | Reverse proxy, SSL termination, static file serving                                    |
+
+### Production Architecture Notes
+
+- **Frontend**: Uses pre-built Next.js static assets served by Nginx (no Node.js runtime needed)
+- **Authentication**: Any OIDC-compatible provider can be used instead of self-hosted Keycloak
+- **Object Storage**: External services (S3, Azure Blob) or self-hosted solutions (MinIO) are both viable
+- **Database**: Consider PostgreSQL clustering or managed database services for high availability
+- **Scaling**: Horizontal scaling is recommended for Django API and Y-Provider services

+
+## 6. Sizing Guidelines
+
+**RAM** – start at 8 GB dev / 16 GB staging / 32 GB prod. Postgres and Keycloak are the first to OOM; scale them first.
+
+> **OS considerations:** Windows systems typically require 10-20% more RAM than Linux due to higher OS overhead. Docker Desktop on Windows also uses additional memory compared to native Linux Docker.
+
+**CPU** – budget one vCPU per busy container until Celery or Next.js builds saturate.
+
+**Disk** – SSD; add 10 GB extra for the Docker layer cache.
+
+**MinIO** – for demos, mount a local folder instead of running MinIO to save 2 GB+ of RAM.

+# Troubleshooting Guide
+
+## Line Ending Issues on Windows (LF/CRLF)
+
+### Problem Description
+
+This project uses **LF (Line Feed: `\n`) line endings** exclusively. Windows users may encounter issues because:
+
+- **Windows** defaults to CRLF (Carriage Return + Line Feed: `\r\n`) for line endings
+- **This project** uses LF line endings for consistency across all platforms
+- **Git** may automatically convert line endings, causing conflicts or build failures
+
+### Common Symptoms
+
+- Git shows files as modified even when no changes were made
+- Error messages like "warning: LF will be replaced by CRLF"
+- Build failures or linting errors due to line ending mismatches
+
+### Solutions for Windows Users
+
+#### Configure Git to Preserve LF (Recommended)
+
+Configure Git to NOT convert line endings and preserve LF:
+
+```bash
+git config core.autocrlf false
+git config core.eol lf
+```
+
+This tells Git to:
+- Never convert line endings automatically
+- Always use LF for line endings in working directory
+
+
+#### Fix Existing Repository with Wrong Line Endings
+
+If you already have CRLF line endings in your local repository, the **best approach** is to configure Git properly and clone the project again:
+
+1. **Configure Git first**:
+   ```bash
+   git config --global core.autocrlf false
+   git config --global core.eol lf
+   ```
+
+2. **Clone the project fresh** (recommended):
+   ```bash
+   # Navigate to parent directory
+   cd ..
+   
+   # Remove current repository (backup your changes first!)
+   rm -rf docs
+   
+   # Clone again with correct line endings
+   git clone git@github.com:suitenumerique/docs.git
+   ```
+
+**Alternative**: If you have uncommitted changes and cannot re-clone:
+
+1. **Backup your changes**:
+   ```bash
+   git add .
+   git commit -m "Save changes before fixing line endings"
+   ```
+
+2. **Remove all files from Git's index**:
+   ```bash
+   git rm --cached -r .
+   ```
+
+3. **Reset Git configuration** (if not done globally):
+   ```bash
+   git config core.autocrlf false
+   git config core.eol lf
+   ```
+
+4. **Re-add all files** (Git will use LF line endings):
+   ```bash
+   git add .
+   ```
+
+5. **Commit the changes**:
+   ```bash
+   git commit -m "✏️(project) Fix line endings to LF"
+   ```
+
+## Minio Permission Issues on Windows
+
+### Problem Description
+
+On Windows, you may encounter permission-related errors when running Minio in development mode with Docker Compose. This typically happens because:
+
+- **Windows file permissions** don't map well to Unix-style user IDs used in Docker containers
+- **Docker Desktop** may have issues with user mapping when using the `DOCKER_USER` environment variable
+- **Minio container** fails to start or access volumes due to permission conflicts
+
+### Common Symptoms
+
+- Minio container fails to start with permission denied errors
+- Error messages related to file system permissions in Minio logs
+- Unable to create or access buckets in the development environment
+- Docker Compose showing Minio service as unhealthy or exited
+
+### Solution for Windows Users
+
+If you encounter Minio permission issues on Windows, you can temporarily disable user mapping for the Minio service:
+
+1. **Open the `compose.yml` file**
+
+2. **Comment out the user directive** in the `minio` service section:
+   ```yaml
+   minio:
+     # user: ${DOCKER_USER:-1000}  # Comment this line on Windows if permission issues occur
+     image: minio/minio
+     environment:
+       - MINIO_ROOT_USER=impress
+       - MINIO_ROOT_PASSWORD=password
+     # ... rest of the configuration
+   ```
+
+3. **Restart the services**:
+   ```bash
+   make run
+   ```
+
+### Why This Works
+
+- Commenting out the `user` directive allows the Minio container to run with its default user
+- This bypasses Windows-specific permission mapping issues
+- The container will have the necessary permissions to access and manage the mounted volumes
+
+### Note
+
+This is a **development-only workaround**. In production environments, proper user mapping and security considerations should be maintained according to your deployment requirements.
+
+## Frontend File Watching Issues on Windows
+
+### Problem Description
+
+Windows users may experience issues with file watching in the frontend-development container. This typically happens because:
+
+- **Docker on Windows** has known limitations with file change detection
+- **Node.js file watchers** may not detect changes properly on Windows filesystem
+- **Hot reloading** fails to trigger when files are modified
+
+### Common Symptoms
+
+- Changes to frontend code aren't detected automatically
+- Hot module replacement doesn't work as expected
+- Need to manually restart the frontend container after code changes
+- Console shows no reaction when saving files
+
+### Solution: Enable WATCHPACK_POLLING
+
+Add the `WATCHPACK_POLLING=true` environment variable to the frontend-development service in your local environment:
+
+1. **Modify the `compose.yml` file** by adding the environment variable to the frontend-development service:
+
+   ```yaml
+   frontend-development:
+     user: "${DOCKER_USER:-1000}"
+     build: 
+       context: .
+       dockerfile: ./src/frontend/Dockerfile
+       target: impress-dev
+       args:
+         API_ORIGIN: "http://localhost:8071"
+         PUBLISH_AS_MIT: "false"
+         SW_DEACTIVATED: "true"
+     image: impress:frontend-development
+     environment:
+       - WATCHPACK_POLLING=true  # Add this line for Windows users
+     volumes:
+       - ./src/frontend:/home/frontend
+       - /home/frontend/node_modules
+       - /home/frontend/apps/impress/node_modules
+     ports:
+       - "3000:3000"
+   ```
+
+2. **Restart your containers**:
+   ```bash
+   make run
+   ```
+
+### Why This Works
+
+- `WATCHPACK_POLLING=true` forces the file watcher to use polling instead of filesystem events
+- Polling periodically checks for file changes rather than relying on OS-level file events
+- This is more reliable on Windows but slightly increases CPU usage
+- Changes to your frontend code should now be detected properly, enabling hot reloading
+
+### Note
+
+This setting is primarily needed for Windows users. Linux and macOS users typically don't need this setting as file watching works correctly by default on those platforms.
