+# Readme #
+This a repository example to practice the Git basic commands.
+
+# First commit #
+The first commit is the creation of the =file-a.md= file and some lines of code.
+
+Then the repository will be enable by 
+
+``` shell
+$ git init
+```
+
+after that our first file has been created and will be filled with the next lines of code using the =echo= command or =Vim= editor:
+
+``` shell
+vi file-a.md
+```
+
+its contents is:
+
+``` shell
+Line 1
+Line 2 
+Line 3
+```
+
+to quit =Vim= editor use =:wq!= in command mode (pressing first the ESC key)
+
+Then, we have to add the file we want to track by =git add <file(s)>= command:
+
+``` shell
+$ git add file-a.md
+```
+
+To finalize the process, we have to use the =git commit= command:
+
+``` shell
+$ git commit -m "first commit"
+[master (root-commit) b441ef4] first commit
+ 1 file changed, 3 insertions(+)
+ create mode 100644 file-a.md
+```
+
+the output from shell should be similar to code section above. Otherwise, you must provide your credentials as a new Git[^1] user with
+
+``` shell
+$ git config --global user.name "Mona Lisa"
+$ git config --global user.email "my_email@domain.com"
+```
+
+# Second commit #
+After the first commit, we can make some modifications to =file-a.md= file:
+
+``` shell
+Line 0
+Line 1
+Line 2
+```
+
+then, following the same procedure create and stage your second commit:
+
+``` shell
+$ git status
+On branch master
+Changes not staged for commit:
+  (use "git add <file>..." to update what will be committed)
+  (use "git restore <file>..." to discard changes in working directory)
+	modified:   file-a.md
+	
+$ git add file-a.md
+$ git commit -m "second commit"
+[master 5fdc115] second commit
+ 1 file changed, 1 insertion(+), 1 deletion(-)
+```
+
+# Difftool #
+To compare to commits, in this case our only commits, we will use the =difftool= command
+
+``` shell
+$ git difftool b441ef4
+```
+here the number =b441ef4= is the commit code number.
+
+A more simple way to observe what modifications on the repository is by using =git show= command
+
+``` shell
+$ git show
+```
+
+You can observe the log by using:
+
+``` shell
+$ git log --graph --pretty
+```
