+# To CGO or to Not CGO
+CGO is required and enabled by default as the package makes use of github.com/mattn/go-sqlite3 but if you require cross-compilation and don't want to bother with  
+CGO you can set the -tags nocgo (alongside CGO_ENABLED=0) and it will switch to using modernc.org/sqlite which does not require CGO.
+
+```
+go build . -tags nocgo
+```
