Miro is a visual workspace and online whiteboard platform that allows teams to collaborate and work together remotely. To familiarize yourself with Miro, start by exploring the Miro Academy, which offers tutorials and guides on creating boards, using templates, and collaboration tips. You can also explore on your own with basic tools like sticky notes, frames, and diagrams, then gradually experiment with more advanced features like integrations and real-time collaboration.
