 ### Bits and bytes
 
-- Add a space between the bits/bytes abbreviation and the number, e.g. `100 MB`, `1 Gbps`
+- Add a space between the bits/bytes abbreviation and the number, e.g. `100 MB`, `1 Gbps`.
 - Use the following abbreviations:

+GB vs GiB is an SI vs binary distinction:
+- GB = 10⁹ bytes = 1,000,000,000 bytes 
+- GiB = 2³⁰ bytes = 1,073,741,824 bytes
+<br/><br/>
+Use GiB/MiB in contexts where technical precision and binary vs decimal distinction is critical, particularly for memory.
