+upgradeHomeRam() Netscript Function
+===================================
+
+.. js:function:: upgradeHomeCores()
+
+    :RAM cost: 3 GB
+
+    If you are not in BitNode-4, then you must have Level 2 of Source-File 4 in order to use this function.
+
+    This function will upgrade amount of CORES on the player's home computer. The cost is the same as if you were to do it manually.
+
+    This function will return true if the player's home computer RAM is successfully upgraded, and false otherwise.
