+# Security Process
+
+If you find a vulnerability in our software, please report it via
+GitHub "Private vulnerability reporting" feature at
+https://github.com/nghttp2/nghttp2/security instead of submitting
+issues on github issue page.  It is a standard practice not to
+disclose vulnerability information publicly until a fixed version is
+released, or mitigation is worked out.
+
+If we identify that the reported issue is really a vulnerability, we
+open a new security advisory draft using [GitHub security
+feature](https://github.com/nghttp2/nghttp2/security) and discuss the
+mitigation and bug fixes there.  The fixes are committed to the
+private repository.
+
+We write the security advisory and get CVE number from GitHub
+privately.  We also discuss the disclosure date to the public.
+
+We make a new release with the fix at the same time when the
+vulnerability is disclosed to public.
+
+At least 7 days before the public disclosure date, we open a new issue
+on [nghttp2 issue tracker](https://github.com/nghttp2/nghttp2/issues)
+which notifies that the upcoming release will have a security fix.
+The `SECURITY` label is attached to this kind of issue.  The issue is
+not opened if a vulnerability is already disclosed, and it is publicly
+known that nghttp2 is affected by that.
+
+Before few hours of new release, we merge the fixes to the master
+branch (and/or a release branch if necessary) and make a new release.
+Security advisory is disclosed on GitHub.

-Security Process
-================
-
-If you find a vulnerability in our software, please send the email to
-"tatsuhiro.t at gmail dot com" about its details instead of submitting
-issues on github issue page.  It is a standard practice not to
-disclose vulnerability information publicly until a fixed version is
-released, or mitigation is worked out.  In the future, we may setup a
-dedicated mail address for this purpose.
-
-If we identify that the reported issue is really a vulnerability, we
-open a new security advisory draft using `GitHub security feature
-<https://github.com/nghttp2/nghttp2/security>`_ and discuss the
-mitigation and bug fixes there.  The fixes are committed to the
-private repository.
-
-We write the security advisory and get CVE number from GitHub
-privately.  We also discuss the disclosure date to the public.
-
-We make a new release with the fix at the same time when the
-vulnerability is disclosed to public.
-
-At least 7 days before the public disclosure date, we will post
-security advisory (which includes all the details of the vulnerability
-and the possible mitigation strategies) and the patches to fix the
-issue to `distros@openwall

-<https://github.com/nghttp2/nghttp2/issues>`_ which notifies that the
-upcoming release will have a security fix.  The ``SECURITY`` label is
-attached to this kind of issue.

-Before few hours of new release, we merge the fixes to the master
