# ValueWriter Example
You are creating a converter for Eclipse NoSQL that will work without a mapping annotation. You can use both ValueWriter and ValueReader.
* **ValueWriter**: This interface represents an instance of Value to write in a database.
* **ValueReader**: This interface represents how the Value will convert to Java application. This interface will use the T get(Class type) and T get(TypeSupplier typeSupplier).
## Steps
* The first step is to create the converter to a custom type database, the ValueWriter.
* ValueWriter created and the Money type will save as String, then the next step is read information to Java application. As can be seen, a ValueReader implementation.
After both implementations have been completed, the last step is to register them into two files:
* `META-INF/services/jakarta.nosql.ValueReader`
* `META-INF/services/jakarta.nosql.ValueWriter`
## Using Docker
1. Install docker: https://www.docker.com/
2. https://store.docker.com/images/mongo
3. Run docker command
4. Run MongoDB: verify MongoDB image name with the command `docker images`, it can be mongodb or mongo, and then execute this command
1. `docker run -d --name mongodb-instance -p 27017:27017 mongo`
## Run the code
With a MongoDB instance running go to the class **App** and have fun.
