+#### Read the [FAQ](https://github.com/hrfee/jfa-go/wiki/FAQ) first!
+
+**Describe the bug**
+
+Describe the problem, and what you would expect if it isn't clear already.
+
+**To Reproduce**
+
+What to do to reproduce the problem.
+
+**Logs**
+
+When you notice the problem, check the output of `jfa-go`. If the problem is not obvious (e.g a panic (red text) or 'ERROR' log), re-run jfa-go with the `-debug` argument and reproduce the problem. You should then take a screenshot of the output, or paste it here, preferably between \`\`\` tags (e.g \`\`\``Log here`\`\`\`). Remember to censor any personal information.
+
+If nothing catches your eye in the log, access the admin page via your browser, go into the console (Right click > Inspect Element > Console), refresh, reproduce the problem then paste the output here in the same way as above.
+
+**Configuration**
+
+If you see it as necessary, include relevant sections of your `config.ini`, for example, include `[email]` and `[smtp]|[mailgun]` if you have an email issue.
+
+**Platform/Version**
+
+Include the platform jfa-go is running on (e.g Windows, Linux, Docker), the version (first line of output by `jfa-go` or Settings>About in web UI), and if necessary the browser version and platform.
