+# Steam Workshop and tooling
+
+## Live-Sync references
+
+After a *Data Center* update, run the game once so MelonLoader regenerates interop assemblies, then from the repo root:
+
+```bash
+python tools/refresh_refs.py
+```
+
+Optionally save a baseline for diffs:
+
+```bash
+python tools/diff_assembly_metadata.py --save-snapshot
+```
+
+After future updates:
+
+```bash
+python tools/diff_assembly_metadata.py
+```
+
+Do **not** commit `*.dll` from `lib/references/` (see `.gitignore`).
+
+## Steam Workshop (research)
+
+Official upload and item layout for *Data Center* Workshop content may be undocumented by the developer. Until documented:
+
+- Treat Workshop delivery as **game-defined** (often content under game data / `StreamingAssets`; MelonLoader mods remain **DLLs in `Mods/`**).
+- The **WorkshopUploader** desktop app (see `WorkshopUploader/`) is the supported path for authors to manage Workshop items and DevServer betas once Steamworks is configured.
+
+## Legal
+
+Do not redistribute game binaries or extracted assets. Workshop packages should contain **your** content only.
+
+## CI / agents
+
+- `FrikaMF.csproj` builds on Windows agents that have either a Steam *Data Center* install **or** a populated `lib/references/MelonLoader/` (from `refresh_refs.py`).
+- `WorkshopUploader` targets `net6.0-windows`; build it on Windows (not Linux-hosted runners unless cross-compilation is configured).
