 University of Delaware administrative cost benchmarking using public data (IRS 990, IPEDS, BLS CPI-U). Ingests data into a local DuckDB database and serves an interactive Dash dashboard for analysis.
 
+## Scope
+
+This project is currently scoped to the **University of Delaware** as a single institution. It tracks:
+
+- **Executive compensation** from IRS 990 Schedule J filings by the University of Delaware (EIN 516000297) and UD Research Foundation (EIN 516017306)
+- **Administrative cost ratios** from IPEDS finance surveys (expenses by function, staffing levels, enrollment)
+- **Endowment performance** and **philanthropic giving** from IPEDS F2 (FASB) financial data
+- **Administrative headcount** via web scraping, currently focused on the **College of Engineering line management** (COE Central, department offices) and the Provost's Office
+
+### Changing the target institution
+
+The institution scope is controlled by constants in `src/admin_analytics/config.py`:
+
+- `UD_UNITID = 130943` -- IPEDS institution identifier. Change this to target a different institution. Look up UNITIDs at the [IPEDS Data Center](https://nces.ed.gov/ipeds/use-the-data).
+- `UD_EINS = [516000297, 516017306]` -- IRS Employer Identification Numbers for 990 filings. Update these to the EINs of the target institution's nonprofit entities.
+
+All IPEDS loaders accept a `unitid_filter` parameter. The scraper URLs in `src/admin_analytics/scraper/directory.py` are UD-specific and would need to be updated for a different institution.
+
+Multi-institution comparisons (AAU peers, Carnegie peers) are planned for a future phase.
