+The Singularity Functions are a special set of Netscript functions that allow the player to control additional aspects of the game such as working for factions/companies, purchasing/installing Augmentations, and creating programs.
 
 The Singularity Functions are **not** immediately available to the player and must be unlocked later in the game.

-The Singularity Functions are unlocked in BitNode-4. If you are in BitNode-4, then you will automatically have access to all of these functions.
-You can use the Singularity Functions in other BitNodes if and only if you have the Source-File for BitNode-4 (aka Source-File 4). Each level of
-Source-File 4 will open up additional Singularity Functions that you can use in other BitNodes. If your Source-File 4 is upgraded all the way to
-level 3, then you will be able to access all of the Singularity Functions.
+The player has access to all of these functions while in BitNode-4. Completing BitNode-4 and gaining its source-file unlocks certain Singularity Functions for use in other BitNodes, with all functions accessible at level 3.
