+# go-gitea-vendor
+Want to vendor all your Go projects on your personal Gitea instance?
+Don't want to bloat your git history?
+Use `go-gitea-vendor` to maintain a separate repo that is only the latest vendoring!
+
+## Usage
+`echo 'EXAMPLE_API_TOKEN' | go-gitea-vendor https://gitea.example.com`
+
+I recommend setting up a chron job or some form of automation for this.
