 #### Installing Key Libraries & Additional Apps
 - Next we need to install a bunch of important libraries, applications, and tools needed to Azerothcore. Run the following command:

+#### Installing CMake
+- Let's make sure that the no version of CMake exists by removing any previous installations of CMake. `sudo apt remove --purge --auto-remove cmake`
+- Next, we'll begin the process to install CMake. Copy this entire block and paste it into your terminal. If you wish to install a different version of CMake, you can update the version and build number to a different CMake version, which can be found on https://cmake.org/download/
+```
+version=3.16
+build=2
+mkdir ~/temp
+cd ~/temp
+wget https://cmake.org/files/v$version/cmake-$version.$build.tar.gz
+tar -xzvf cmake-$version.$build.tar.gz
+cd cmake-$version.$build/
+```
+- After a bunch of text, hit 'Return' or 'Enter' once on your keyboard.
+- Now let's install CMake. Copy this entire block and paste it into your terminal.
+```
+./bootstrap
+make -j$(nproc)
+sudo make install
+```
+- After the building is complete (and you get the command line back), hit 'Return' or 'Enter' once on your keyboard to install CMake
+- Let's verify that you're running the correct version of CMake by using the `cmake --version` command. Note: If CMake Version doesn't work, close your terminal, reconnect, and try the version command again.
+- Navigate back to your primary directory by typing `cd`.
+- Let's clean up the install of CMake with `rm -rf temp`. Now let's take a look at configuring the database.

+- As the `azcore` user, let's navigate back to the home directory `cd`
 - Now we need to go to the compile server folder `cd azeroth-server`
+- We need to make a folder for our data files and navigate to it `mkdir data;cd data`
 - Let's download the data files required. `curl https://wow.heyaapl.com/data.zip --output data.zip`
 - Let's unzip the main data directory `unzip data.zip`
-- We need to navigate to the data folder to continue unzipping the child folders `cd data`
-- No we will unzip all child zip files `unzip '*.zip'`

 #### Set up the server config files
 - Using SFTP, navigate to `/home/azcore/azeroth-server/etc` and download the authserver.conf.dist and worldserver.conf.dist to your local machine.
