 - `repub.toml`: example runtime config with feed definitions and Scrapy overrides
+- `fixtures/local-feed.rss`: simple local RSS fixture for `file://` feed testing
+
+## Local File Feed
+
+`repub` already accepts absolute `file://` feed URIs. To point it at the demo fixture, generate an absolute URI like this from the repo root:
+
+```shell
+python3 -c 'from pathlib import Path; print(Path("demo/fixtures/local-feed.rss").resolve().as_uri())'
+```
+
+Then use that value in a config entry:
+
+```toml
+[[feeds]]
+name = "local-demo"
+url = "file:///absolute/path/to/demo/fixtures/local-feed.rss"
+```
