 ## Client Libraries
 
+This section contains example code for client libraries in several languages. Please remember that when modeling your data in Pilosa, it is best to keep row and column ids sequential. It is not wise to use the output of a hash, or randomly distributed ids with Pilosa.

 Pilosa lays out data first in rows, so queries which get all the set bits in one or many rows, or compute a combining operation on multiple rows such as Intersect or Union are the fastest. Pilosa also has the ability to categorize rows into different "frames" and quickly retrieve the top rows in a frame sorted by the number of bits set in each row.
 
+Please note that Pilosa is most performant when row and column IDs are sequential starting from 0. You can deviate from this to some degree, but if you try to set a bit with column ID 2^63, bad things will start to happen.

+Please note that while user ID 99999 may not be sequential with the other column IDs, it is still a relatively low number. 
+Don't try to use arbitrary 64-bit integers as column or row IDs in Pilosa - this will lead to poor performance, out of memory errors, and more.
