First modification and commit

[AndreWeiner]

Hi @MehdiMak96 , let's make the first change on the linear_algebra_basics.ipynb notebook.

1. make sure that you are working on the correct branch (not master): git status; you can change branches using git checkout branch_name (always use the tab-key for autocompletion)
2. open the linear algebra notebook and make a modification

   cd notebooks
   jupyter lab
   # now you are working in the browser
   # open linear_algebra_basics.ipynb ( left side menu; double click)
   # add some markdown or code to one of the cells
   # close the notebook: File -> Shut Down

3. go back to the top-level of the repository and run git status again; there should be exactly one modified file, namely linear_algebra_basics.ipynb
4. stage the modification using

   git add  notebooks/linear_algebra_basics.ipynb

5. check again that the modification is staged git status (the color should have changed from red to orange)
6. commit the change; mention this issue in the commit message using the syntax #issue_number; the number of this issue should be 6

   git commit -m"Make first modification according to issue #6."

7. push the changes on your branch to the central repository

   git push origin name_of_your_branch

   Best, Andre

Hi Mahdi, I guess something went wrong since you haven't pushed anything to the repository. You can try to repeat the steps. Carefully read the Git output to find potential issues. Otherwise, we go through the process together on Monday. Best, Andre

The commit and the new branch have been correctly pushed to the repository, nice! The commit message could have been better, though. Next time, don't forget to mention the issue you are referring to. A potential commit message could have been: Add small change to linear algebra notebook to test git/github workflow; related to issue #6.
