Minor suggestions for Git for Collaboration

[sofer]

Could replace:

touch time/newfile.txt
open time/newfile.txt

With:

date > time/newfile.txt

or

echo "first version" > time/newfile.txt 

You say, "Repeat step 2...step 6". It is not immediately obvious which steps you are referring to.

Typos under https://github.com/NataliaLKB/learn-git-basics#when-should-you-commit:
"The first, is that a you..."
*"...depending on the extend of..."
*"...what tasks where completed..."

This is just such a marvellous piece of work. I am very happy with where we are setting the bar for future tutorials.

@sofer since this is still for beginners I thought it was more clear to create the file, open it, and edit it in different steps. However if it isn't more clear, then happy to change it (This isn't a beginners guide to the command line though)
