```
GET https://xoops.gitbook.io/xoops-installation-guide/appendixes/appendix-5-increase-security-of-your-xoops-installation.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

### Option 2 — Browse the documentation index

### Option 3 — Retrieve the full documentation corpus
