# Best practices Code Please refer to the other pages in the [Get started](/xena-developer/development/get-started.md) section of our developer site. Design We provide all developers with our CSS and style guide to help you easily design your app or plugin to match the rest of Xena. Please refer to our [Design Guide](/xena-developer/user-interface/styleguide.md) for a complete overview of how to style different elements. Regarding icons, please use [Font Awesome](https://fontawesome.com/icons?d=gallery\&q=s\&s=solid). Exceptions could be plugins that mimic other existing systems. Workflow Have a clear flow in your app, to help the user accomplish his task. To do this, make wise use of hierarchy, tabs and/or steps. Also, carefully consider where it makes most sense to locate your app. Does it need a menu for itself with its own views? Or just a spot in an existing menu or a tab in a view? Communication Using a simple yet professional language will help the user to understand your message quickly. End users may not need to know every detail, or a full explanation. If a decision can be made with just a few facts, it may be a better solution. Don't: * Don't use humor or jokes in warnings or everyday tasks. * Don't address the user by name, unless there is a good contextual reason. * Don't invent new terms for key features. E.g. don't say "contact" when you mean "partner". Do: * Check your spelling. * Ensure your texts are clear and natural. * Stick to Xena's color scheme, especially regarding alerts and primary buttons. Documentation Provide the help users might need. You can create written documentation, videos or tutorials for your app and paste a link in your app's description in the Xena App Store. Again, keep it in a clear, accurate and natural language. We recommend you provide this documentation in the languages of your primary users. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://dev.xena.biz/xena-developer/the-possibilities/best-practices.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
