 Returns if `key` exists.
 
-Since Redis 3.0.3 it is possible to specify multiple keys instead of a single
-one. In such a case, it returns the total number of keys existing. Note that
-returning 1 or 0 for a single key is just a special case of the variadic usage,
-so the command is completely backward compatible.
-
-The user should be aware that if the same existing key is mentioned in the
-arguments multiple times, it will be counted multiple times. So if `somekey`
-exists, `EXISTS somekey somekey` will return 2.

-@integer-reply, specifically:
-
-- `1` if the key exists.
-- `0` if the key does not exist.

-Since Redis 3.0.3 the command accepts a variable number of keys and the return
-value is generalized:
-
-- The number of keys existing among the ones specified as arguments. Keys
-  mentioned multiple times and existing are counted multiple times.
+@integer-reply, specifically the number of keys that exist from those specified as arguments.
