 ## Development
 
-tbd
+Requirements:
+
+- Docker Engine: `~1.12`
+- Docker Compose: `~1.8`
+
+Application is prepared for run in container, you can start development same way:
+
+1. Clone this repository: `git clone git@github.com:keboola/dynamodb-extractor.git`
+2. Change directory: `cd dynamodb-extractor`
+3. Build services: `docker-compose build`
+4. Run tests `docker-compose run --rm app-tests` (runs `./tests.sh` script)
+
+After seeing all tests green, continue:
+
+1. Run service: `docker-compose run --rm app` (starts container with `bash`)
+2. Load sample data: `php loadSampleData.php`
+3. Write tests and code
+4. Run tests: `./tests.sh`
+
+To simulate real run:
+
+1. Create data dir: `mkdir -p data`
+2. Follow configuration sample and create `config.json` file and place it to your data directory (`data/config.json`)
+3. Simulate real run (with entrypoint command): `php ./src/app.php run ./data`
+
+### Tests
+
+- all in one: `./tests.sh`
+- or separately, just check `tests.sh` file contents
