# Welcome! > :hammer\_pick: **Work in progress** > > This page is actively updated with contents from labs, courses, work, and research. ## About This GitBook is a personal knowledge base built from hands-on experience and study across platforms like [Hack The Box](https://academy.hackthebox.com/) (HTB) and [SANS GIAC](https://www.sans.org/sg_en). It is a place to consolidate my learning - from walkthroughs and tool usage to theory snippets - gathered during courses, labs, certifications, and real-world engagements. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
