-#### Notes: 
+#### Notes:
 
 - Omitted actual plastic for printing. Any conventional 3d printing plastic should do (PLA, PETG, ABS),
 but beware of PLA's thermal limits. Higher infill is recommended for all parts.
 - For joining two racks, you will need 8 M3 hex nuts, and 8 M3x10 FHCS (TODO confirm)
-- Main front rails are mounted using M4 hex nuts and screws.
-- Side rails are mounted using M3 screws
+- Main front rails use M4 hex nuts and screws.
+- Side rails are mounted using M3 hex nuts and screws
