+To test zooid locally without having to set up SSL, follow these simple instructions:
+
+Create a `compose.yml` file with the following content:
+
+```yml
+services:
+  zooid:
+    image: ghcr.io/coracle-social/zooid
+    restart: unless-stopped
+    container_name: zooid
+    volumes:
+      - ./zooid/config:/app/config:z
+      - ./zooid/media:/app/media:z
+      - ./zooid/data:/app/data:z
+    networks:
+      - nginx
+
+  nginx:
+    image: nginx
+    restart: unless-stopped
+    container_name: nginx
+    volumes:
+      - ./zooid/nginx.conf:/etc/nginx/conf.d/nginx.conf
+      - /dev/null:/etc/nginx/conf.d/default.conf:ro # avoids conflicts with default config
+    ports:
+      - "3334:80"
+    networks:
+      - nginx
+
+networks:
+  nginx:
+    driver: bridge
+```
+
+Make a `zooid` folder with the following structure:
+```
+zooid/
+├── config/
+│   └── relay.toml
+├── data/
+├── media/
+└── nginx.conf
+```
+
+Your `nginx.conf` should have the following content:
+
+```json
+server {  
+    listen 80;
+    listen [::]:80;
+    server_name localhost;
+
+    location / {
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection "upgrade";

+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+
+        proxy_pass http://zooid:3334;
+        proxy_read_timeout 86400;
+    }

+To run, just run either `podman compose up` OR `docker compose up`
