# Low-code Development

Frends uses BPMN 2.0 notation to define APIs, integrate systems, and automate processes. Frends provides enhancements to the notation with Handlebars-enabled C# programming, making it possible to create most anything that is visually pleasing, easy for non-programmers to read and understand, and requiring only minimal programming by the developer.

## Process Editor

At the core of Frends is our prized Process Editor, which utilises BPMN 2.0 notation to create the integration flows or Processes. With the drag and drop editor, it is easy to both visualize what is happening and in what order, as well as create the logic to do exactly what you want and need to do. No coding expertise required to understand the Processes.

## Coding features

While most of the logic can be done with only the graphical elements, including the powerful Tasks to perform pre-defined actions, Frends is specifically a low-code platform for integrations. Thus, if you need and want to, you can include C# code in the Processes to fine tune more complex logic.&#x20;

Code can be included as separate shapes to perform actions in task-like manner, or you can include short pieces of code into any text input field using Handlebars-like syntax. Most parameter fields can also be changed to take in C# code instead of text, in case the value is coming from variables instead of predefined text.

And finally, when handling data from the Process flow in other parts of the Process, you can use References such as **#trigger**, **#var** and **#env** to access values from the start condition that triggered the Process, variables defined in the Process, as well as Environment Variables that are centrally defined for each execution Environment, respectively. These work exactly like variables would in standard C# code and are accessible Process-wide after being initialized in the Process.
