+# Git Add
+
+By default, when you create a new file inside your Git project, it is not being tracked by Git. So to tell git that it should start tracking the file, you need to use the `git add` command.
+
+The syntax is the following:
+
+```bash
+git add NAME_OF_FILE
+```
+
+In our case, we have only 1 filed inside our project called `README.md`, so to add this file to Git, we can use the following command:
+
+```bash
+git add README.md
+```
+
+If you then run `git status` again, you will see a different output:
+
+```
+Changes to be committed:
+  (use "git rm --cached <file>..." to unstage)
+        new file:   README.md
+```
+
+Here you would see that there are now some changes staged and ready to be committed. Also, Git tells us that the `README.md` is a new file that was just staged and has not been tracked before.
+
+In case that you have a couple of files, you could list them all divided by space after the `git add` command to stage them all rather than running `git add` multiple times for each individual file:
+
+```bash
+git add file1.html file2.html file3.html
+```
+
+With the above, we will add the 3 files by running `git add` just once, however in some cases, you might have a lot of new files, and adding them one by one could be highly time-consuming. 
+
+So there is a way to stage absolutely all files in your current project, and this is by specifying a dot after the `git add` command as follows:
+
+```bash
+git add .
+```
+
+> Note: You need to be careful with this as in some cases, there might be some files that you don't want to add to Git.
+
+With that, we are ready to move on and learn about the `git commit` command.
