@@ -21,6 +21,31 @@ Contributions will be distributed with Vim under the Vim license.  Providing a
 change to be included implies that you agree with this and your contribution

+## 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.
+
+When merging PRs into Vim, the current maintainer @chrisbra usually adds missing

-	""		Complete only the first match.

-			the original string is used and then the first match

-			complete till longest common string.
-	"list:lastused" When more than one buffer matches, list all matches
-			and sort buffers by time last used (other than the
-			current buffer).
+	Some useful combinations of colon-separated values:
+	"longest:full"		Start with the longest common string and show
+				'wildmenu' (if enabled).  Does not cycle
+				through full matches.
+	"list:full"		List all matches and complete first match.
+	"list:longest"		List all matches and complete till the longest

+	"list:lastused"		List all matches.  When completing buffers,

+	"noselect:lastused"	Do not preselect the first item in 'wildmenu'
