+
+## Supported Versions
+
+The latest release of *dufs* is supported. The fixes for any security issues found will be included
+in the next release.
+
+
+## Reporting a Vulnerability
+
+Please [use *dufs*'s security advisory reporting tool provided by
+GitHub](https://github.com/sigoden/dufs/security/advisories/new) to report security issues.
+
+We strive to fix security issues as quickly as possible. Across the industry, often the developers'
+slowness in developing and releasing a fix is the biggest delay in the process; we take pride in
+minimizing this delay as much as we practically can. We encourage you to also minimize the delay
+between when you find an issue and when you contact us. You do not need to convince us to take your
+report seriously. You don't need to create a PoC or a patch if that would slow down your reporting.
+You don't need an elaborate write-up. A short, informal note about the issue is good. We can always
+communicate later to fill in any details we need after that first note is shared with us.
