+## Type: Issue only
+The below lays out the `issue-only` tag type. This tag will not be registered as a tag that users can run, and only exists to
+register responses for issues. It follows the rules that `Issue responses` below sets out.

+```markdown
+type: issue-only
+issues: <issue1> || <issue2> || <issue 3> ...
+
+---
+
+Text
+```
+
+## Issue responses
+Issue responses work with `text`, `text-raw` and `issue-only` types. Any issues listed are registered to have the content of the tag as the issue response.
+Different issues are delimited by `||`, allowing differently worded issues to have the same response.
+When a message or log file is shared, it will be scanned to check if it contains any known issues. Responses to the issues found will be sent in a single embed.
+`text` and `text-raw` types with issues listed can still be called with the tag command; they do not lose their functionality.
+```markdown
+type: text
+issues: <issue1> || <issue2> || <issue 3> ...
+

+Old server versions do not support Java 16, which Geyser requires. Paper 1.15.2 and higher can be forced to use Java 16 by adding `-DPaper.IgnoreJavaVersion=true`
+to the JVM startup flags.
+Servers on 1.8.8 can use Java 16 if `use-native-transport` is set to `false` in `server.properties`, although Geyser
+does not support versions below 1.12.2

+If **Geyser** is showing this error, there are are a few likely causes:
+A: You reloaded Geyser or the server, which is unsupported. Please do a full restart instead.
+B: Your Geyser jar is corrupted, and you need to re-download it.
+C: Geyser failed to start for a different reason. Check the start of your server logs for a different error explaining why it failed to start.
