Installation of linux command should have bouble dash

[AlfCano]

Hi,
Thanks for everything you do.
This is just to note that on the Linux install section:

pip3 install –upgrade pip

in the https://github.com/ccbogel/QualCoder front page, should be:

pip3 install --upgrade pip

for it to work.

Thank you. I have updated that typo now.
