+NetCDF (with file extensions `*.nc`) is a self-describing, machine-independent data format of array-oriented scientific data.
 
 - **Self-describing** means that the `*.nc` files include not only the data itself, but also a *header* with `metadata` that describes the layout of the data.
 - **Machine-independent** means that the  `*.nc` files can be accessed by computers with different ways of storing integers, characters, and floating-point numbers.

 ### 1.1 NetCDF metadata
 
-Metadata enables users of data from different sources to decide which quantities are comparable, and facilitates building applications with powerful extraction, regridding, and display capabilities.
+Metadata is typically described as *information about the data* and enables users of data from different sources to decide which quantities are comparable. This facilitates building applications with powerful extraction, regridding, and display capabilities.
 
 To facilitate this process, there are conventions for CF (Climate and Forecast) metadata. These are designed to promote the processing and sharing of files created with NetCDF. The conventions define metadata that provide a definitive description of what the data in each variable represents, and the spatial and temporal properties of the data. Learn more about the CF metadata conventions <a href="http://cfconventions.org" target="_blank">here</a>.
