+Before you create an issue, make sure it has not already been reported.
+
+Then, make sure the following things are included in your issue:
+
+- wufuc version (can be viewed in Add & Remove Programs).
+- Operating system version and Service Pack (including 32- or 64-bit).
+- Short description of the issue.
+- Elaborate steps to reproduce the bug/issue being reported.
+- Attach wufuc's log file (located at `C:\ProgramData\wufuc\wufuc.log`).
+- Any supporting information that could help solve/understand the issue.
+
+Any issues that do not include these, or go more than a week without a
+response from the original poster will be subject to closure at my discretion.
+
+If you have questions, be sure to check here:
+- https://github.com/zeffy/wufuc/blob/master/FAQ.md
+
+It is common for issues to go unanswered for several days or even weeks,
+so please do not take offense at this. 
+
+I read every issue and usually only reply if there is clarification needed,
+or if there is a new release pending that will solve the issue.
