+## Signing-off commits
+
+While not required, it's recommended to use **Signed-off commits** to ensure
+transparency, accountability, and compliance with open-source best practices.
+Signed-off commits follow the [Developer Certificate of Origin (DCO)][15],
+which confirms that contributors have the right to submit their changes under

+messages, verifying that the contributor agrees to the project's licensing
+terms.  To sign off a commit, simply use the -s flag when committing:
+
+```sh
+git commit -s
+```
+
+This ensures that every contribution is properly documented and traceable,
+aligning with industry standards used in projects like the Linux Kernel or
+the git project.  By making Signed-off commits a standard practice, we help
+maintain a legally compliant and well-governed codebase while fostering trust
+within our contributor community.

-			the original string is used and then the first match

-	"list:lastused" When more than one buffer matches, list all matches

+	"list:full"		List all matches and complete first match.
+	"list:longest"		List all matches and complete till the longest

+To configure the tabpanel, use following options: 'tabpanel',
+'showtabpanel', 'tabpanelopt'.
+The 'tabpanel' and 'showtabpanel' options are function similar to the
+'statusline' or 'tabline'.
+
+The "columns:" of 'tabpanelopt' option specifies the width of the tabpanel:
