 All README examples show configurations with remark42 on its own subdomain, i.e. `https://remark42.example.com`. However, it is possible and sometimes desirable to run remark42 without a subdomain, but just under some path, i.e.  `https://example.com/remark42`.
 
-- The nginx.conf would then look something like:
+- The frontend URL looks like this: `s.src = 'https://example.com/remark42/web/embed.js;`
+
+- The backend `REMARK_URL` parameter will be `https://example.com/remark42`
+
+- And you also need to slightly modify the callback URL for the social media login API's:
+  - Facebook Valid OAuth Redirect URIs: `https://example.com/remark42/auth/facebook/callback`
+  - Google Authorized redirect URIs: `https://example.com/remark42/auth/google/callback`
+  - Github Authorised callback URL: `https://example.com/remark42/auth/github/callback`
+
+### docker-compose configuration
+
+Both Nginx and Caddy configuration below relies on remark42 available on hostname `remark42`, which is achieved by having `container_name: remark42` in docker-compose.
+
+Example `docker-compose.yaml`:
+
+```yaml
+version: '2'
+services:
+  remark42:
+    image: umputun/remark42:latest
+    container_name: remark42
+    restart: always

+        - REMARK_URL=https://example.com/remark42/
