 - Disable debug mode by default.
+
+# Getting started & FAQ
+
+Use following docker images:
+- `m1k1o/neko:latest` - for Firefox.
+- `m1k1o/neko:chromium` - for Chromium Ungoogled (needs `--cap-add=SYS_ADMIN`).
+- `m1k1o/neko:base` - for custom base.
+
+Networking:
+- If you want to use n.eko in **external** network, you can omit `NEKO_NAT1TO1`. It will automatically get your Public IP.
+- If you want to use n.eko in **internal** network, set `NEKO_NAT1TO1` to your local IP address (e.g. `NEKO_NAT1TO1: 192.168.1.20`)-
+
+Why so many ports?
+- WebRTC needs UDP ports for each channel it creates towards users.
+- Every user will need 2 UDP ports (for getting audio/video and sending mouse positions).
+- You can freely limit number of UDP ports. But you can't map them to diferent ports.
+  - This **WONT** work: `32000-32100:52000-52100/udp`
+- You can change API port (8080).
+  - This **WILL** work: `3000:8080`
+
+Behind reverse proxy?
+- Nginx configuration: https://github.com/nurdism/neko/issues/111#issuecomment-742656957
+- Apache configuration: https://github.com/nurdism/neko/blob/cad98a62a5bd7f1daf2c11980631bb14ba81a1f6/docs/apache-proxypass-config.md#example-apache-config
+- Traefik configuration: https://github.com/m1k1o/neko-vpn/blob/a1b934515dcf597992a515d61d307c2450a11002/docker-compose.yml#L38-L43

+- Check this out: https://github.com/m1k1o/neko-vpn
+
+Accounts:
+- There are no accounts, display name (a.k.a. username) can be freely chosen. Only paword needs to match. Depeding on which password matches, visitor gets its privilege:
+  - Anyone, who enters with `NEKO_PASSWORD` will be **user**.
+  - Anyone, who enters with `NEKO_PASSWORD_ADMIN` will be **admin**.
+
+Screen size
+- Only admins can change screen size.
+- You can set default screen size, but this size **MUST** be one from list, that your server supports.
+- You will get this list in frontend, where you can choose from.
