|
||||
just a few small guidelines you need to follow.
|
||||
|
||||
## Contributor License Agreement
|
||||
|

||||
go get -u -d github.com/GoogleCloudPlatform/govanityurls
|
||||
cd $(go env GOPATH)/github.com/GoogleCloudPlatform/govanityurls
|
||||
```
|
||||
|
||||
Edit `app.yaml` with your domain and git repo information.
|
||||
|
||||
```
|
||||
env_variables:
|
||||
DOMAIN: go.grpcutil.org
|
||||
REPO: https://github.com/rakyll/grpcutil
