 You can use the official image from [docker hub](https://hub.docker.com/r/srcd/gitbase/tags/) to quickly run gitbase:
 ```
-$ docker run --rm --name gitbase -p 3306:3306 -v /my/git/repos:/opt/repos srcd/gitbase:latest
+docker run --rm --name gitbase -p 3306:3306 -v /my/git/repos:/opt/repos srcd/gitbase:latest
 ```
 
 If you want to speedup gitbase using indexes you must run a pilosa container:
 ```
-$ docker run -it --rm --name pilosa -p 10101:10101 pilosa/pilosa:v0.9.0
+docker run -it --rm --name pilosa -p 10101:10101 pilosa/pilosa:v0.9.0
 ```
 
 Then link the gitbase container to the pilosa one:
 ```
-$ docker run --rm --name gitbase -p 3306:3306 --link pilosa:pilosa -e PILOSA_ENDPOINT="http://pilosa:10101" -v /my/git/repos:/opt/repos srcd/gitbase:latest

 ```

 ### Download and use the binary
 
 Check the [Releases](https://github.com/src-d/gitbase/releases) page to download the gitbase binary.

 Because gitbase uses [bblfsh's client-go](https://github.com/bblfsh/client-go), which uses cgo, you need to install some dependencies by hand instead of just using `go get`. Use this instead:
 
 ```
-$ go get -d github.com/src-d/gitbase
-$ cd $GOPATH/src/github.com/src-d/gitbase
-$ make dependencies
+go get -d github.com/src-d/gitbase
