 # team-calendar
-Know when everyone in your team is available / busy with a single glance.
+
+***effortlessly know*** when everyone in your team is ***available / busy***.
+
+## Why?
+
+Viewing your team's availability in a single view is
+a time-consuming problem that all organizations face.
+
+There are a few companies that have *attempted* to solve this problem
+in a variety of ways, however there is no "*standard*" or *generally accepted*
+solution to the problem
+
+## What?
+
+Team calendar sharing simplified.
+
+## How?
+
+Using the Google Calendar API, get the availability of all members
+of a team and display them in a single intuitive view.
+
+> **Note**: *Ask* ***lots*** *of questions as issues in this repo
+ so we can evolve the requirements/solution collectively.
