# Steps to create Root Span
* Extract HTTP Headers from request.
* Create SpanContext from HTTP Headers, if available.
* Extract FlowId, if applicable.
* Create SpanBuilder with relevant tags.
* Build Root Span from SpanBuilder and SpanContext (FINALLY!)
* Tag Root Span with relevant info.

# Steps to use a Span
* Execute code using new span as child of root/parent span.
* Execute code using current span.
* Remember to close a span (Important!)
* Log info on current Span.
* Log Error on current Span with special tags and proper formatting.
