+Let's do something fun!
+
+On our server, we will download a zip file, unzip the contents, make a small change and re-zip everything together. Ready? First, let's understand the zip command.
+
+* Connect to the server
+* Go to folder `myFirstFolder`
+* Zip the two files you created
+
+```bash
+zip myArchive.zip myFile.txt file3.txt
+```
+
+* Check the contents of the zip archive
+
+```bash
+unzip -l myArchive.zip
+```
+
+Couple of notes:
+
+* `-l` is a parameter. You can see what these parameters mean by doing `man unzip`.
+* Google is your friend!
+
+### Let us download a zip from the Internet and extract its contents
+
+Let's go:
+
+```bash
+cd
+wget http://bit.ly/anArchive -O myName.zip
+ls
+```
+
+* First I check the contents to make sure it's what I wanted:
+
+    ```
+    unzip -l myName.zip
+    ```
+
+* If I am satisfied, I can safely extract
+
+    ```
+    unzip myName.zip
+    ```
