 ## Development Setup
 
-### Cloning the Repository (Private repo only)
-
-1. `git config --global url."git@github.com:".insteadOf "https://github.com/"`
-    - By default, `go get` does not work for private GitHub repos. This will fix that.
-2. `go get github.com/vulcanize/vulcanizedb`
-3. `cd $GOPATH/src/github.com/vulcanize/vulcanizedb`
-4. `dep ensure`

 ### Creating/Using a test node
 
 Syncing the against the public network takes many hours for the initial sync and will download 20+ GB of data.
