A Minor Mistake in Documentation About Setting Environments for CentOS 7

[SaltedFishLZ]

Describe the bug Hi, the document tells us to install some additional packages to set the environment. However, some packages like octave and qt-creator are not included in the default CentOS/RHEL repos. We need to add the EPEL repo first.

To Reproduce Steps to reproduce the behavior:

1. sudo yum install -y git octave octave-io jq

Expected behavior yum will tells you that octave, octave-io and jq cannot be found.

Desktop (please complete the following information):

• OS: CentOS 7.9 (20-09) Clean Installation

Additional context

Please add a note to tell new users to add the EPEL repos.

or maybe add the following line

sudo yum -y install epel-release
