+## Deploy your own Larapaper
+
+To self-host larapaper with serverless transforms, you have to use [our fork](https://github.com/spark-hpi/larapaper) of [larapaper](https://github.com/usetrmnl/larapaper). We will once again use [docker compose](../How to Home Server/03 Installing Docker.md) for this.
+
+We are currently working on merging our fork back into the main repo, but this might take a while. Check for updates on this topic.
+
+Begin by creating a `compose.yaml` with the following contents:
+
+```yml
+services:
+  larapaper:
+    container_name: larapaper
+    image: ghcr.io/spark-hpi/larapaper:latest
+    ports:
+      - "4567:8080"
+    environment:
+      - APP_KEY=base64:<TODO>
+      - PHP_OPCACHE_ENABLE=1
+      - TRMNL_PROXY_REFRESH_MINUTES=15
+      - DB_DATABASE=database/storage/database.sqlite
+      - TRANSFORM_RUNNER_URL=transform-runner:3000
+      # - MULTI_USER_MODE=1 # if you are planning to use larapaper with multiple users
+    volumes:
+      - database:/var/www/html/database/storage
+      - storage:/var/www/html/storage/app/public/images/generated
+    restart: unless-stopped
+
+  transform-runner:
+    container_name: transform-runner
+    image: ghcr.io/spark-hpi/larapaper-serverless-runner:latest
+    security_opt: [seccomp=unconfined]
+    environment:
+      - TRANSFORM_TIMEOUT=30 # maximum time a transform may run
+      - TRANSFORM_MEMORY_LIMIT=134217728 # (128MB) the amount of memory a single transform may use, killed if the limit is exceeded
+
+volumes:
+  database:
+  storage:
+```
+
+Replace `<TODO>` inside the `APP_KEY` with the output of the command `openssl rand -hex 16 | base64`.
