Subject: ||= in an expression

Hello,

I new to Ruby and curious about this language I do use (yeet).

I was browsing through some libraries/modules and I found a line looking 
like

a[:i] ||= "a string"

I could not find this syntax in any manual online (and googling "||=" is 
not of much help :-( )

Can anyone tell me what it means

TiA
