     * Install the git version of minetest (or otherwise install 0.4.13 or other version compatible with the map generators used by chunkymap)
     such as:
 ```
-	#if you have a version before 2016-03-23:
-	if [ -f rename-deprecated.sh ]; then
-      rm rename-deprecated.sh
-	fi

-    wget https://github.com/expertmm/minetest-chunkymap/raw/master/install-chunkymap-on-ubuntu-from-web.sh
-    chmod +x install-chunkymap-on-ubuntu-from-web.sh
-    ./install-chunkymap-on-ubuntu-from-web.sh

-	#then (shutdown minetest first then) create singleimage map:
-    sudo python chunkymap/singleimage.py
-	#then start generator which will update player entries on your website (can be made anonymous--see viewchunkymap.php):
-    sudo python chunkymap/generator.py

     OPTION 2: IF you are using Ubuntu go to a terminal, cd to this directory,  
     then switch user to the one that will run minetestserver
     (since install-chunkymap-on-ubuntu.sh DOES replace "/home/owner" with current user's home [replace-with-current-user.py, which is automatically called by install, will change /home/owner to current user's directory in each script that install copies to $HOME/chunkymap])  
     then go to Terminal and run:
 ```
-    minetestserver
+minetestserver
 ```
     then when it is finished loading, press Ctrl C then run:
 ```
-    chmod +x install-chunkymap-on-ubuntu.sh && ./install-chunkymap-on-ubuntu.sh
+chmod +x install-chunkymap-on-ubuntu.sh && ./install-chunkymap-on-ubuntu.sh
 ```
     Installing as cron job is OPTIONAL (and NOT recommended):
     * IF you are using a distro such as Ubuntu 14.04 where first line of /etc/crontab is "m h dom mon dow user command" then if you want regular refresh of map then run:
