+# Plan for accessibility and sustainable development
+
+## Accessibility
+
+We aim to develop the application with a focus on WCAG and accessibility. The goal is to make the website usable with a keyboard, screen reader, and across different screen sizes.
+
+Accessibility measures we will follow during development:
+
+- Use semantic HTML elements where appropriate, such as `search`, `article`, headings, and lists.
+- Provide clear `label` elements for form inputs.
+- Provide descriptive alternative text for images.
+- Use sufficient color contrast and avoid using color alone to communicate important information.
+- Maintain a logical heading structure.
+- Create a responsive interface that works on both small and large screens.
+- Check accessibility throughout development and test that the application can be navigated and used with a keyboard.
+
+The current implementation already uses semantic search with an associated label, alternative text for flag images, and a semantic list for displaying countries.
+
+## Sustainable Development
+
+We aim to reduce unnecessary resource usage without negatively affecting the user experience.
+
+Sustainable development measures we will follow:
+
+- Keep the application simple and avoid unnecessary dependencies.
+- Limit the amount of data loaded and processed to what is actually needed.
+- Avoid unnecessary API calls and network traffic.
+- Use lazy loading for images so they are loaded only when needed.
+- Reuse components and keep the codebase clean and maintainable.
+- Use Vite to optimize the production build.
+- Consider image size and format to reduce unnecessary data usage.
+
+We also consider maintainability an important part of sustainable development. A simple component structure, TypeScript, and consistent formatting and linting make the application easier to maintain and extend without unnecessary rewriting.
