What you can use Notes & Docs for
By using Notes & Docs, you can create, collaborate on, and share any relevant information that your team is relying on, both in your boards and cards context.
Board Notes
Board notes - like this guide - are tied to the current Trello board. They are great for sharing general work-related information with your team, like meeting notes, guidelines, team objectives, project documentation, and more.
Card Notes
On the other hand, card notes are specific to individual Trello cards and can be used for detailed task descriptions, comments, research materials, client information, etc. They are ideal for documenting any content related to that specific task.
