TWO LICENCES, AND WHICH ONE COVERS WHAT
---------------------------------------

1. THE SOFTWARE — Apache License, Version 2.0.
   Everything that is code: app/, components/, lib/, cf/, scripts/, tests/, the
   build and the migrations. The full text is in LICENSE, and at
   https://www.apache.org/licenses/LICENSE-2.0
   You may run it, change it, and run your own version of it. Keep this notice.

2. THE DATA — CC0 1.0 Universal (public domain dedication).
   Everything that is a figure or a description of one: data/prices.json,
   data/state-prices.json, data/conditions.json, data/synonyms.json,
   data/unpriceable.json, everything published under /data/, every CSV and JSON
   the API exports, and the register's own aggregate counts.
   https://creativecommons.org/publicdomain/zero/1.0/

   The federal figures themselves are U.S. Government works and are already in
   the public domain. Our part — the plain-language labels, the synonyms, the
   coverage statements, the combination rules, the locality derivation and the
   arrangement of all of it — is dedicated to the public domain as well.
   Attribution is welcome and is not required.

   How to cite, if you want to: each published file carries its own how_to_cite
   line. /data.json is the DCAT-US v1.1 catalog that describes all of them.

THIRD-PARTY SOURCES
-------------------

The dollar figures are read from published U.S. federal files (CMS, AHRQ and
others named row by row). Every row in data/prices.json carries the file it came
from, its year, its basis and the population it describes, and
data/verify_price_table.py re-derives each one from that file and exits non-zero
if it does not reproduce. Cite the federal source for the figure; cite this
project for the arrangement.

Third-party npm dependencies keep their own licences; see package.json and the
licence files under node_modules/ after an install.

NO ENDORSEMENT
--------------

Nothing here is published by, endorsed by, or on behalf of any federal agency.
