+*  Compile this project (`mvn clean install` or `mvn clean install -DskipTests` if you want to skip the tests)
 *  You can set properties for extraction in the config file (e.g., number of loglines produced per file). Examples of config and template files are available on the `src/test/resources` folder (e.g., `auth-config.yaml`for auth log data). 
 *  Transform the CSVs into OTTR format using the config file. By default, the following script should work on the example file. (```java -jar target/slogert-<SLOGERT-VERSION>-jar-with-dependencies.jar -c src/test/resources/auth-config.yaml```)
 *  The result would be produced in the `output/` folder
