 ## ⌨️ Setup
 
-> Pleas note that Pingvin Share is in early stage and could include some bugs
+> Note: Pingvin Share is in its early stages and may contain bugs.
 
-### Recommended installation
+### Installation with Docker (recommended)
 
 1. Download the `docker-compose.yml` file
 2. Run `docker-compose up -d`
 
 The website is now listening available on `http://localhost:3000`, have fun with Pingvin Share 🐧!
 
+### Stand-alone Installation
+
+Required tools:
+
+- [Node.js](https://nodejs.org/en/download/) >= 14
+- [Git](https://git-scm.com/downloads)
+- [pm2](https://pm2.keymetrics.io/) for running Pingvin Share in the background
+
+```bash
+git clone https://github.com/stonith404/pingvin-share
+cd pingvin-share
+
+# Checkout the latest version
+git fetch --tags && git checkout $(git describe --tags `git rev-list --tags --max-count=1`)
+
+# Start the backend
+cd ../backend
+npm install
+npm run build
+pm2 start --name="pingvin-share-backend" npm -- run prod
+
+# Start the frontend
+cd frontend
+npm install
+npm run build
+pm2 start --name="pingvin-share-frontend" npm -- run start
+```
+
+The website is now listening available on `http://localhost:3000`, have fun with Pingvin Share 🐧!
+
+### Integrations
+
+#### ClamAV (Docker only)
+
+ClamAV is used to scan shares for malicious files and remove them if found.
+
+1. Add the ClamAV container to the Docker Compose stack (see `docker-compose.yml`) and start the container.
+2. Docker will wait for ClamAV to start before starting Pingvin Share. This may take a minute or two.
+3. The Pingvin Share logs should now log "ClamAV is active"
+
+Please note that ClamAV needs a lot of [ressources](https://docs.clamav.net/manual/Installing/Docker.html#memory-ram-requirements).
+
 ### Additional resources
 
 - [Synology NAS installation](https://mariushosting.com/how-to-install-pingvin-share-on-your-synology-nas/)
 
 ### Upgrade to a new version
 
-Run `docker compose pull && docker compose up -d` to update your docker container
+As Pingvin Share is in early stage, see the release notes for breaking changes before upgrading.
+
+#### Docker
+
+```bash
+docker compose pull
+docker compose up -d
+```
+
+#### Stand-alone
+
+Repeat the steps from the [installation guide](#stand-alone-installation) except the `git clone` step.
