-Now, I say almost-as-marvelous because if you use `git clone` you may run into issues about your $GOPATH. It happens. Since I haven't figured out how to consistently `go get` all the dependencies I need for a given Go project from esoteric locations outside my $GOPATH (in part because I have so many esoteric locations and don't want to haggle with forever adjusting/amending my $GOPATH extensioners), I usually just wind up running `go run main.go` or `go build -o gogs` and `go get`ting the dependencies it complains about one-by-one.

+## Config.
+Once you've got the project, you'll need to configure your own `GOGS_TOKEN` and `GOGS_URL` variables. 
+<br>
+You can use
+```bash
+$ go install # From inside the base of the project.
+```
+which'll create a file called `.go-gogs-cli.yaml` that likes to live at `$HOME/.go-gogs-cli.yaml`. It handles configuring your __Gogs url__ and __token__, like such:
+```yaml
+GOGS_TOKEN: 0e6709o05da4753dddf5f592374fdc263f02n801
+GOGS_URL: http://my.goggers.me
+```
+Fill that in for your own self. 
+<br>
+<br>
+__Or__, if you'd rather use environment variables, that'll work fine too. 
+```bash
+export GOGS_TOKEN=asdlfj239r029fzsfasf923r23f
+export GOGS_URL=http://my.goggers.me
