 ## Flags
 
+Put flags to the **BINARY**, not an init script. If you are on OpenWRT you should put the flags inside the script: open `/etc/init.d/youtubeUnblock` with any text editor, like vi or nano and put your flags after `procd_set_param command /usr/bin/youtubeUnblock` line.
+
 Available flags:
 
 - `--sni-domains=<comma separated domain list>|all` List of domains you want to be handled by SNI. Use this string if you want to change default domain list. Defaults is `googlevideo.com,ggpht.com,ytimg.com,youtube.com,play.google.com,youtu.be,googleapis.com,googleusercontent.com,gstatic.com,l.google.com`. You can pass **all** if you want for every *ClientHello* to be handled.
