# Server App Configs

Podman deployment configuration for two homelab servers: Dankserver and Dankclaw.

This repository is the single source of truth for both hosts. It tracks the
container stacks and the LLM inference fleet. Edits flow through this repo,
then deploy to the targets with `scripts/deploy.sh` (one script per target
covers both workloads).

> 2026-08-22: the former `vllmScripts` repository (LLM fleet) is merged
> into this repo with its full git history. Its knowledge base now lives at
> [docs/LLM/index.md](LLM/index.md).
