+* Apply Iranian Docker registry mirrors (ArvanCloud, Haiocloud, Iranserver, etc.)
+* DNS auto-backup before changes
+* Support for Debian/Ubuntu systems
+
+## Usage
+
+```bash
+git clone https://github.com/Linuxmaster14/iran-docker.git
+cd iran-docker
+chmod +x iran-docker.sh
+sudo ./iran-docker.sh
+```
+
+## Menu Options
+
+1) Set DNS
+2) Install Docker
+3) Update Docker
+4) Set Docker Proxy
+5) Exit
+
+## Supported DNS Providers
+
+* Shecan
+* Radar
+* Electro
+* Begzar
+* DNS Pro
+* 403
+* Google
+* Cloudflare
+
+## Supported Docker Proxies
+
+* https://docker.iranserver.com
+* https://docker.haiocloud.com
+* https://registry.docker.ir
+* https://docker.arvancloud.ir
+* https://focker.ir
