# SQLiteDB
This is an example project, generated by AntOS Development Kit
## Howto
Use the Antedit command palette to access to the SDK functionalities:
1. Create new project
2. Init the project from the current folder located in side bar
3. Build and run the project
4. Release the project in zip package
## Set up build target
Open the `build.json` file from the current project tree and add/remove
build target entries and jobs. Save the file
