 ## Adding a new target format
-Adding a new target format requires a developer implement [ConversionTarget](./api/src/main/java/org/apache/xtable/spi/sync/ConversionTarget.java). Once you have implemented that interface, you can integrate it into the [ConversionController](./core/src/main/java/org/apache/xtable/conversion/ConversionController.java). If you think others may find that target useful, please raise a Pull Request to add it to the project.
