 ## Notes
 
 1.  This script will not point major upgrades (i.e. from v25 to v26) to your old library. You should **first perform a library backup**, install the new major version, and then restore the library backup in the new version.
-2.  It is recommended to run `installJRMC` as your normal system user (i.e. don't run it with `sudo`). Services are installed for the user that executes the script so do not execute as root unless you want to install system-wide services like `createrepo` (see services section below for more information).

-
-1.  Extract:
-```
-unzip ./installJRMC.zip
-```
-2.  You may need to make the script executable:
-```
-chmod +x ./installJRMC
-```
-3.  Run the script using default options (see Options section below):
-```
-./installJRMC
-```
-You will be prompted to enter your sudo password to install dependencies, etc.
 
 ## Options
