+# Git Command Line commands
+
+## Start working on your project

+
+* When you are on your Dashboard, click on the project that you'd like to copy, which you'll find at the right side of your screen

+## Basic commands

+```
+cd NAME-OF-PROJECT-OR-FILE

+```
+cd ../
+```
+
+* Go to the master branch to pull the latest changes from there
+```
+git checkout master
+```
+
+* Download the latest changes in the project, so that you work on an up-to-date copy (this is important to do every time you work on a project)
+```
+git pull
+```
+
+* Create a branch (remember that spaces won't be recognized, you need to use a hyphen or underscore)
+```
+git checkout -b NAME-OF-BRANCH
+```

+```
+git checkout NAME-OF-BRANCH
