-**Avoid performing an NVRAM commit**: This option prevents any nvram (configuration) modification. Essentially any modified value + save would not be permanent.\\
-**Enable cprintf output to console**:FIXME\\
+**Avoid performing an NVRAM commit**: Checking this stops nvram (configuration) variables from being permanently saved. This makes it possible to safely experiment with settings, since changes reset at reboot.
-**Enable cprintf output to /tmp/cprintf**:FIXME\\
-**Enable DDNS output to /tmp/mdu-***:This option allows the diagnostic of the DDNS client to be fully logged under /tmp/\\
+**Enable cprintf output to console**:FIXME
-**Enable segfault logging**:By default segfault errors are not logged into syslog facility, enabling this option you make this happen.\\
-**Count cache memory and buffers as free memory**:On by default, it has to do with the way Linux handles RAM allocation which is split in Used+cache+buffer. Enabling this option cache and buffer are counted as free.\\
+**Enable cprintf output to /tmp/cprintf**:FIXME
-**Avoid displaying LAN to router connections**:Enabling this option will prevent LAN connections from the CONNTRACK related info e.g. QoS/View Details.\\
+**Enable DDNS output to /tmp/mdu - **This option allows the DDNS diagnostics to be fully logged in the /tmp/ directory.
+**Enable segfault logging**: By default, segfault errors are not logged via the syslog functiony. Enabling this option causes them to be logged. Segfaults are Linux errors caused by a program trying to read from or write to an illegal memory location.
+**Count cache memory and buffers as free memory**: This affects how Linux handles RAM allocation, which is split into Used + cache + buffer. If enabled, this causes cache memory and buffer to be counted as free. (Default: enabled).
+**Avoid displaying LAN to router connections**: Enabling this prevents LAN connections from being displayed in menus that show //conntrack//-related data, such as the //QoS/View Details// menu.\\

+\\ **Kernel printk log level**:FIXME
+**Do not restart the following process if they die**:- crond/dnsmasq/hotplug2/igmprt: Usually FreshTomato restarts dying processes. In some exceptional cases, you may want to prevent this from happening.
+**Set "no-cache" in httpd header - **A very common issue is that is cached browser content can create errors/display issues in the web interface. Usually, refreshing the page, via CTRL+F5, fixes this problem by forcing a cache flush. However, setting this parameter is an alternative solution. This instructs the browser not to perform any caching while on FreshTomato web interface pages. Both methods are particularly useful after firmware upgrades.

-**Kernel printk log level**:FIXME\\
-**Do not restart the following process if they die**: crond/dnsmasq/hotplug2/igmprt: Usually dying processes are automatically restarted in FreshTomato. In some exceptional case you might want to prevent this from happening.\\
-**Set "no-cache" in httpd header**:One of the most common issue especially after upgrading the firmware is cached browser content that creates errors/issues on the GUI. Usually reloading the interface via CTRL+F5 forces a cache-flush but an alternative is to set this parameter and instruct the browser not to perform any caching while on the FT's administration pages.\\
