-The component used to manage a node as a progress bar, changing the size and scale of the node
+Basic Druid progress bar component. Changes the size or scale of a node to represent progress.
 
+### Setup
+Create progress bar component with druid: `progress = druid:new_progress(node_name, key, init_value)`
+
+### Notes
+- Node should have maximum node size in GUI scene, it's represent the progress bar maximum size
+- Key is value from druid const: "x" or "y"
+- Progress works correctly with 9slice nodes, it tries to set size by _set_size_ first, until minimum size is reached, then it sizing via _set_scale_
+- Progress bar can fill only by vertical or horizontal size. For diagonal progress bar, just rotate node in GUI scene
+- If you have glitchy or dark texture bugs with progress bar, try to disable mipmaps in your texture profiles
