The application development documents provide reference for you to develop applications using the APIs provided by OpenHarmony. They walk you through how to use JavaScript APIs to develop applications on the standard system.
The documents are carefully organized as follows:
### Getting Started
[Here](quick-start/Readme-EN.md) you can learn how to better prepare yourself for application development.
Browse the documents on how to use DevEco Studio and how to quickly build your first application.
Don't forget to check out the package structure of OpenHarmony applications and resource file categories.
### Development
To facilitate your application development, we provide development guidelines for key features.
First thing first, familiarize yourself with the two cornerstone frameworks in OpenHarmony applications:
DevEco Studio is a high-performance integrated development environment (IDE) recommended for developing OpenHarmony applications.
[Here](https://developer.harmonyos.com/en/docs/documentation/doc-guides/ohos-deveco-studio-overview-0000001263280421) you can learn everything about DevEco Studio, including how to use this tool to create a project and sign, debug, and run an application.
### Hands-On Tutorials
To make you better understand how functions work together and jumpstart your application development projects, we provide stripped-down, real-world [samples](https://gitee.com/openharmony/app_samples/blob/master/README.md).
### API References
API references encompass all components and APIs available in OpenHarmony, helping you use and integrate APIs more effectively.
They are organized as follows:
-[Component Reference (JavaScript-based Web-like Development Paradigm)](reference/arkui-js/Readme-EN.md)
-[Component Reference (TypeScript-based Declarative Development Paradigm)](reference/arkui-ts/Readme-EN.md)
-[API Reference](reference/apis/Readme-EN.md)
### Readme
