-# Size for the ram folder, it defines the size the log folder will reserve into the RAM.
-# If it's not enough, log2ram will not be able to use ram. Check you /var/log size folder.
-# The default is 40M and is basically enough for a lot of applications.
+# Size for the ram folder, it defines how much space is reserved in the RAM for the logs.
+# Ensure 'SIZE=' is larger than your /var/log directory.
+#  - (If not enough is reserved, log2ram will fail to start).
+# Ensure logrotate is set to keep your /var/log directory from growing too large.
+#  - (If your /var/log directory grows larger than 'SIZE=', new logs entries can't be written).
+# The default of 128M is adequate for a lot of applications.
 # You will need to increase it if you have a server and a lot of log for example.
