 - **Low usage teams** (1-5 MB/user/month) - Primarily use text-messages and links to communicate. Examples would include software development teams that heavily use web-based document creation and management tools, and therefore rarely upload files to the server. 
  
-- **Medium usage teams** (5-25 MB/user/month) - Use a mix of text-messages and shared documents and images to communicate. Examples might include business teams that may commonly drag and drop screenshots, PDFs and Microsoft Office documents into Mattermost for sharing and review.
