 `go mod init`
 
-1. Set your base URL prefix via flag or env variable
-2. `gomodinit` will default to the current directory name as the module, otherwise the first command argument
+`gomodinit` walks up the current dir path until it finds something vaguely resembling a URI (i.e. a path part with at least one `.`) 
+and constructs a `go mod init <path>` call from it.
 
 ## This seems like a trivial thing
