getting started documentation has flaws, corrections suggested (http://mesos.apache.org/gettingstarted/)

Getting started documentation, while having great virtues, has room for improvement:

1) Documentation is illogical and wrong for this part:
" $ wget http://www.apache.org/dist/mesos/0.25.0/mesos-0.25.0.tar.gz
$ tar -zxf mesos-0.25.0.tar.gz" ...then, later:
" # Install a few utility tools
$ sudo yum install -y tar wget
..obviously using tar and wget is not possible before installing them.

2) Although vi is fine for many, utility tools having:
sudo yum install -y tar wget nano
might make editing e.g. the WANDISCO -repo file way easier for newbies.

3) Advice to launch Mesos with localhost option ( " ./bin/mesos-master.sh --ip=127.0.0.1 --work_dir=/var/lib/mesos " ) will lead into a state where Mesos UI can not be reached in port :5050 in a production environment e.g. in AWS EC2. Mentioning this would help, not hinder deployment.
