+# RAGFlow integration
+
+This repo-side slice adds:
+
+- `tools/ragflow_tool.py`
+  - `ragflow_ingest(document_url, dataset)`
+  - `ragflow_query(query, dataset, limit=5)`
+- `scripts/ragflow_bootstrap.py`
+  - fetches the upstream RAGFlow Docker bundle
+  - runs `docker compose --profile cpu up -d` or `gpu`
+
+## Deployment
+
+Bootstrap the upstream CPU stack locally:
+
+```bash
+python3 scripts/ragflow_bootstrap.py --profile cpu
+```
+
+Dry-run only:
+
+```bash
+python3 scripts/ragflow_bootstrap.py --profile cpu --dry-run
+```
+
+Fetch files without launching Docker:
+
+```bash
+python3 scripts/ragflow_bootstrap.py --no-up
+```
+
+Default bundle target:
+
+- `~/.hermes/services/ragflow`
+
+## Runtime configuration
+
+Optional environment variables:
+
+- `RAGFLOW_API_URL` — defaults to `http://localhost:9380`
+- `RAGFLOW_API_KEY` — Bearer token for authenticated RAGFlow APIs
+
+## Supported document types
+
+RAGFlow ingest accepts:
+
+- PDF: `.pdf`
+- Word: `.doc`, `.docx`
+- Presentations: `.ppt`, `.pptx`
+- Images via OCR: `.png`, `.jpg`, `.jpeg`, `.webp`, `.bmp`, `.tif`, `.tiff`, `.gif`
+- Text and codebase documents: `.txt`, `.md`, `.rst`, `.html`, `.json`, `.yaml`, `.yml`, `.toml`, `.ini`, `.py`, `.js`, `.ts`, `.tsx`, `.jsx`, `.java`, `.go`, `.rs`, `.c`, `.cpp`, `.h`, `.hpp`, `.rb`, `.php`, `.sql`, `.sh`
+
+## Example tool usage
+
+```json
+{"document_url":"https://arxiv.org/pdf/1706.03762.pdf","dataset":"research-papers"}
+```
+
+```json
+{"query":"What does the paper say about attention heads?","dataset":"research-papers","limit":5}
+```
+
+## Use cases
+
+- research papers
+- technical documentation
+- OCR-heavy image workflows
+- ingested codebases and architecture docs
