+## RSS ingestion workflow
+
+Run `db/migrations/004_n8n_ingestion.sql` in DBeaver first. It creates the
+idempotent database ingestion function and adds a verified starter set of RSS
+sources. It is safe to run the whole file again.
+
+Then import `workflows/02-fetch-news-to-web.json` into n8n and select the same
+PostgreSQL credential on both PostgreSQL nodes. Keep the workflow inactive for
+the first test and click **Execute workflow**. The workflow:
+
+- loads every enabled row from `news_sources`;
+- reads RSS feeds and keeps entries from the last 14 days;
+- classifies entries with local keyword rules, without an AI API;
+- upserts articles and publishes today's web report;
+- does not send email.
+
+After the manual test succeeds and the web page shows today's report, activate
+the workflow. Its schedule is 07:30 in `Asia/Shanghai`.
+
+New RSS sources can be added later with an `INSERT` into `news_sources`; the
+workflow reads that table on every run, so the workflow itself does not need to
+be edited. Set `enabled = FALSE` to pause a source without deleting it.
