+is used to create the <filepath>swicertstore.dat</filepath> file that contains
+certificates and their capabilities. SWI uses <filepath>Swicertstore.dat</filepath> file
+to verify the SIS files being installed and do a capability check. </p> </li>

+<section><title>Typical uses</title><p><b> Creating swicertstore.dat file</b></p> <p>The
+swicertstore tool creates the <filepath>swicertstore.dat</filepath> file.
+This file contains certificates and their capabilities which SWI uses to validate
+the SIS files being installed on the device. For more information on creating <filepath>swicertstore.dat</filepath> file,
+see <xref href="GUID-CF0D81FC-B28C-5AB1-BF99-A1247E31ACBF.dita">Creating swicertstore.dat
+file</xref>. </p><p><b>Using console-based SWI</b> </p> <p>Native software
+can be installed on the device using a console-based tool. This tool can be
+used from EShell to install, uninstall or upgrade native software on the device.
+For more information on using this tool, see <xref href="GUID-DA8908E9-28C7-5200-A5B2-EC1ED60ABE90.dita">Using
