Answer
The LABEL instruction adds metadata to an image. A LABEL is a key-value pair. To include spaces within a LABEL value, use quotes and backslashes as you would in command-line parsing.
A few usage examples:
LABEL "com.example.vendor"="My Company"
LABEL com.example.label-with-value="foo"
LABEL version="1.0"
LABEL description="Label with multiple-line text \
is supported as well."
