It will add everything by itself, but you might have to enable obfuscation support manually.
"Support Protocol Obfuscation" and "Use obfuscation for outgoing connections" -> You are in hybrid mode, fully supporting obfuscated and non-obfuscated connections.
"Accept only obfuscated connections" -> You support only obfuscated connections, this will most probably have a negative effect on the number of sources and no positive effects for normal users.
