+
+Our team will triage your report and keep you informed about the progress.
+We may ask questions or request further guidance on reproduction of the vulnerability in the comments of the advisory, which will be publicized.
+
+Additionally, we may ask you to independently verify our patch, which will be available in the private advisory branch. Please do not publish your vulnerability during the process or before coordinated public disclosure from our side. We try to adhere to common standards of publication within 90-Days of disclosure.
+
+Depending on your decision to accept or deny credit for the vulnerability, you will be publicly attributed to the vulnerability and may be mentioned in our announcements.
 
 At the current time we do not have the financial ability to reward bounties, 
 but in extreme cases will at our discretion consider a reward.
