+# Verify the `records` program with CrateDB
+
+Records: SQL for Humans™
+
+## About
+
+This folder includes software integration tests for verifying
+that the [Records] Python program works well together with [CrateDB].
+
+Records is a very simple, but powerful, library for making raw SQL
+queries to most relational databases. It uses [SQLAlchemy].
+
+Records is intended for report-style exports of database queries, and
+has not yet been optimized for extremely large data dumps.
+
+## What's Inside
+
+- `example.sh`: A few examples that read CrateDB's `sys.summits` table
+  using the `records` program. A single example that inserts data into
+  a column using CrateDB's `OBJECT` column.
+
+## Install
+
+Set up sandbox and install packages.
+```bash
+pip install uv
+uv venv .venv
+source .venv/bin/activate
+uv pip install -r requirements.txt
+```
+
+## Synopsis
+Install packages.
+```shell
+pip install --upgrade records sqlalchemy-cratedb
+```
+Define database connection URL, suitable for CrateDB on localhost.
+For CrateDB Cloud, use `crate://<username>:<password>@<host>`.
+```shell
+export DATABASE_URL="crate://"
+```
+Invoke query.
+```shell
+records "SELECT * FROM sys.summits WHERE region ILIKE :region" region="ortler%"
+```
+
+## Tests
+
+Run integration tests.
