+# Simplest GraphQl Server
+
+Sometimes these things don't really have to be super complicated. 
+Has anyone seen the amount of modules that Apollo brings with it? 
+Yeah... Perhaps great for a gateway but, 
+overkill for something dead simple.
+
+This repo explores making the tiniest GraphQl server possible. 
+Some use cases (maybe):
+
+- Quick Lambda functions
+- Intermediary service/api layer between two rest APIs
+- Building something _FAST_
