GBrain has published a detailed installation guide for its AI agent knowledge base system, outlining the setup and configuration process. Users are instructed to clone the repository, install the Bun runtime, and configure necessary API keys, including OpenAI and optionally Anthropic. The system, built on PGLite, operates without a server and recommends a MECE directory structure for organization. Key functionalities include signal detectors, Brain-ops, and specifications, with a two-step file import and indexing process. The guide also covers setting up scheduled tasks and system integrations, with the entire installation estimated to take 30 minutes.
