## Overview

Red Pitaya Knowledge Base is a documentation collection, not an application runtime. Its visible subject areas cover active-learning electronics, FPGA tutorials, signal processing, and measurement teaching. The tree supports these as distinct content branches, but the README and sampled sources do not establish navigation or cross-links between them. The sampled configuration identifies `index` as the master document and enables the custom GitHub source-link extension; content-level connections are therefore omitted.

Main entry points: [`conf.py`](https://github.com/redpitaya/redpitaya-knowledgebase/blob/master/conf.py) (Sphinx configuration), [`index.rst`](https://github.com/redpitaya/redpitaya-knowledgebase/blob/master/index.rst) (Knowledge base), [`_extensions/github.py`](https://github.com/redpitaya/redpitaya-knowledgebase/blob/master/_extensions/github.py) (GitHub source links)
