+# Microblog Example: Netlify Background Uploads
+
+This document shows how to generate the canonical microblog example so image uploads run through Netlify Background Functions and Filecoin Onchain Cloud instead of a VPS-hosted upload process.
+
+Relevant files:
+- schema: `apps/example/microblog.schema.json`
+- generated Netlify artifacts: `out/microblog/netlify.toml`, `out/microblog/netlify/functions/`
+
+## 1. Build the microblog app
+
+```bash
+th build apps/example/microblog.schema.json --chain filecoin_calibration --out out/microblog
+```
+
+Because the schema includes:
+
+```json
+{
+  "app": {
+    "deploy": {
+      "netlify": {
+        "uploads": {
+          "provider": "filecoin_onchain_cloud",
+          "runner": "background-function"
+        }
+      }
+    }
+  }
+}
+```
+
+the build emits:
+- `out/microblog/netlify.toml`
+- `out/microblog/netlify/functions/tokenhost-upload-start.mjs`
+- `out/microblog/netlify/functions/tokenhost-upload-status.mjs`
+- `out/microblog/netlify/functions/tokenhost-upload-worker-background.mjs`
+- `out/microblog/NETLIFY-UPLOADS.md`
+
+The generated manifest is also wired so the browser upload client talks to:
+- `POST /__tokenhost/upload`
+- `GET /__tokenhost/upload-status?jobId=...`
+
+## 2. Set Netlify environment variables
+
+Set these in Netlify with **Functions** scope:
+
+- `TH_UPLOAD_FOC_PRIVATE_KEY`
+- `TH_UPLOAD_FOC_CHAIN=314159`
+- `TH_UPLOAD_FOC_COPIES=1`
+
+Optional:
+
+- `TH_UPLOAD_FOC_COMMAND=npx -y foc-cli`
+- `TH_UPLOAD_FOC_WITH_CDN=true`
+- `TH_UPLOAD_FOC_DEBUG=true`
+
+Important:
+- runtime secrets must come from Netlify environment variables
+- do not put the private key in `netlify.toml`
+
+## 3. Deploy to Netlify
+
+Deploy the generated build root so Netlify sees:
+- `ui-site/` as the publish directory
+- `netlify/functions/` as the functions directory
+
+The generated `netlify.toml` already configures those paths and the upload redirects.
+
+## 4. Expected runtime flow
+
+1. Browser uploads file bytes to `POST /__tokenhost/upload`
+2. Start function stores the request in Netlify Blobs and returns `202` with `jobId`
+3. Netlify background worker runs `foc-cli upload`
+4. Worker stores success or failure result in Netlify Blobs
+5. Browser polls `/__tokenhost/upload-status?jobId=...` until complete
+
+## Current status
+
+This generated target is meant to remove the VPS requirement for FOC uploads.
+
+What is implemented in Token Host now:
+- schema/build support for a Netlify upload deployment target
+- generated Netlify functions scaffolding
+- manifest/runtime wiring compatible with the existing async browser upload client
+
+What still needs real-world validation:
+- Netlify runtime compatibility for `foc-cli`
+- final deploy ergonomics and any provider-specific edge cases
