+# Prerequisite Scraping Commands
+
+Run all commands from `backend/`.
+
+## Common command
+
+```bash
+uv run manage.py scrape_prereqs --all-course-codes --semesters 2026C --max-requests 100 --sleep-seconds 0.1 --jitter-seconds 0.1
+```
+
+What it does:
+- `--all-course-codes`: loads one course/CRN pair per course code from the DB.
+- `--semesters 2026C`: limits the DB query to semester `2026C`.
+- `--max-requests 100`: caps total requests after deduplication.
+- `--sleep-seconds 0.1`: fixed delay between requests.
+- `--jitter-seconds 0.1`: adds random delay in `[0, 0.1]` seconds per request.
+
+## Other useful forms
+
+```bash
+uv run manage.py scrape_prereqs --pair "CIS 1210:14309"
+uv run manage.py scrape_prereqs --input-file courses/data/prereq_scrapes/targets.sample.json
+uv run manage.py scrape_prereqs --all-course-codes --semesters all
+```
+
+## Output location
+
+By default, output JSON files are written in this directory:
+
+- `courses/data/prereq_scrapes/`
+
+## Populate structured prereqs into DB
+
+After scraping, use the `populate_prereqs` command to parse the JSON files and write structured prereq links into the DB.
+
+```bash
+# Dry-run first (no DB writes)
+uv run manage.py populate_prereqs --semesters 2026C --dry-run
+
+# Apply writes
+uv run manage.py populate_prereqs --semesters 2026C
+```
+Use `--scrape-file <path>` to target a specific scrape JSON.
+Use `--clear-existing` only if you want to replace existing prereq links for matched courses.
+
+## Notes
+
+- If a semester value fails (for example typo or unavailable code), run with a known semester code, or use `--semesters all`.
+- To see all command options:
+
+```bash
+uv run manage.py scrape_prereqs --help
+```
