+curl-bash-template.sh
+=====================
+
+So you've got a neat project and you want to be able to have others get it up and running quickly, eh?
+
+You'd like them to be able to do something like this and have your service installed, eh?
+
+```bash
+curl -L install.example.io | bash
+```
+
+Well, this is a collection of scripts that you can include in your repo to do just that.
+
+Just modify `get.sh` to point to your repo (you could host this on `install.my-project.io`, for example)
+and modify `local.sh` for your specific project.
+
+Currently supports:
+
+	* macOS's launchd
+	* Linux's systemd
+
+Make Your Project Layout Like This
+----------------------------------

+http_get <url> <filepath>   uses curl or wget to download a file
