 # guac-install
 
 Script for installing Guacamole 1.1.0 on Ubuntu 16.04 or newer (with MySQL, or remote MySQL). It should also work on pure [Debian](https://www.debian.org/), [Raspbian](https://www.raspberrypi.org/downloads/raspbian/) or [Kali Linux](https://www.kali.org/). I have tested this with Debian 10.3.0 (Buster). **If other versions don't work please open an issue.** It is likely due to a required library having a different name.
 
 Run script, enter MySQL Root Password and Guacamole User password. Guacamole User is used to connect to the Guacamole Database.
 
-The script attempts to install tomcat9 by default. It will fall back on tomcat8 **if the available version is 8.5.x or newer**, otherwise it will fall back to tomcat7. If you want to manually specify a tomcat version there's a commented out line you can modify. Have at it.
+The script attempts to install `tomcat9` by default (it will fall back on `tomcat8` **if the available version is 8.5.x or newer**, otherwise it will fall back to `tomcat7`). If you want to manually specify a tomcat version there's a commented out line you can modify. Have at it.
 
 If you're looking to also have NGINX / Let's Encrypt / HTTPS click [HERE](https://github.com/bigredthelogger/guacamole)
 
 ## MFA/2FA
 
-By default the script will not install MFA support (QR code for Google/Microsoft Authenticator, Duo Mobile, etc. or Duo Push), if you do want MFA support you need to specify the `-t` or `--totp` or for Duo `-d` or `--duo` flags on the command line. Or modify the script variables `installTOTP=true` or `installDuo=true`. **Do not install both**
