Normally, [ and ] are special characters in regular expressions. \ escapes them so that they equate to a [ or ] character, rather than a special character.

\[\[[a-zA-Z]*\]\] is a regular expression.

\[\[ matches "[["
[a-zA-Z]* matches zero or more alpha characters, both upper and lowercase
\]\] matches "]]"

Therefore, the purpose of this regular expression is to remove any instances of [[something]] or [[anything]] or [[]]
