 ## Bitmap
 
-### BSETBIT key offset value
 
-Sets or clear the bit at `offset` in the binary data sotred at `key`.
-The bit is either set or cleared depending on `value`, which can be either `0` or `1`.
-The *offset* argument is required to be qual to 0, and smaller than
-2^23 (this means bitmap limits to 8MB).
+### BGET key
+
+Returns the whole binary data stored at `key`.
 
 **Return value**
 
-int64 : the original bit value stored at offset.
+bulk: the raw value of key, or nil when key does not exist.
 
 **Examples**
 
 ```
