+# [Data]nymizer demo
+
+## Get started
+
+1. Install `docker` and `docker-compose` to your development environment.
+2. Go to `demo` directory:
+
+``` shell
+cd demo
+```
+and run:
+
+``` shell
+make bootstrap
+```
+
+It starts docker container with Postgresql, download demo database [PostgreSQL Sample Database](https://www.postgresqltutorial.com/postgresql-sample-database/), unpack it and restore to new `dvdrental` database.
+
+3. For dumping this base, run:
+
+``` shell
+make dump
+```
+It makes new `/tmp/fake_dump.sql` file with fake rows in tables from `dvdrental.yml` configuration.
+
+You can change configuration file and try again.
