+## Ackee android test task
+This test task that was written based on the following description: https://github.com/AckeeCZ/android-task-rick-and-morty#readme.
+In this project, I used the Compose toolkit for defining the UI layer and Coroutines for handling asynchronous tasks. It is the first time I have used these libraries in a project.
+Normally, I use default XML layouts and RxJava. You can find an example of my "study" e-shop application with XML/RxJava on https://gitlab.fel.cvut.cz/barysole/pda-sw-e-shop.
+
+The application uses the modern Material Design 3 component library, and because of that, some elements look different from the design. I have decided that it is not a problem for this test task.

+## KNOWING ISSUES
+- Problem: The characters list doesn't save its scrolling position after navigating to the character detail screen and back.
+Analysis: LazyColumn gets the characters list from the ViewModel flow by using the ".collectAsLazyPagingItems()" method, and this method retrieves only part of the characters list after navigation.
