 # Installation
 ## Prerequisites
-* A websever running PHP 7.4 or better with the mysqli native client library
+* A websever running PHP 8.0 or better with the mysqli native client library
+This code should work with earlier versions of PHP but is not supported.
 * A database running MariaDB 10.0+ (or MySQL 5.6+)
 * ImageMagick 6.x or better with the ImageMagick PHP library (imagick) installed
 * Basic ability to use an xxMP stack (e.g. LAMP, WAMP, etc.)

 ## Basic Coniderations
 The application is designed to have simple, user-friendly URLs. For example,
-putting the base files in a subdirectory /qsl resultes in the URL
-https://example.com/qsl for the main application and https://example.com/qsl/load
+putting the base files in a subdirectory `/qsl` resultes in the URL
+`https://example.com/qsl` for the main application and `https://example.com/qsl/load`
 for the ADIF loader. All references to includes, configs, images, etc. are 
 all relative pathed so the application should be installable virtually anywhere.
 
 In order to make this as platform agnostic as possible, all temporary information
 is stored in the MySQL database. In order to accomodate large ADIF imports,
 the staging column type for the pre-commit data is a MySQL LONGTEXT field. This
 will create a tremendous amount of empty-but-used space in MySQL when using

 # Using Smooth QSL
-For hams, all the hams need is the "load key" set in qslconf.php. Smooth QSL
+For hams, all the hams need is the "load key" set in `qslconf.php`. SmoothQSL
 operates on a semi-trust basis in that hams are relied upon to use their
 legitimate call signs as is expected throughout amateur radio. Set a strong
 "load key" as that is the only protection against mischef such as loading
 bogus QSOs or malicious actors attempting to DoS the database by filling it up
 or overworking the system.
 
 The load process uses the following workflow:
-1. Navigate to https://example.com/qsl/load
+1. Navigate to `https://example.com/qsl/load`
 2. Enter the callsign of the station operator, the load key, and select
 the ADIF file. Upload the ADIF file.
 3. Review the ADIF checkload on the next screen. Click Commit
-4. A "receipt" page will apepr.
+4. A "receipt" page will appear.
 
 The QSL retrieval process is straight forward:
-1. A ham navigates to https://example.com/qsl
+1. A ham navigates to `https://example.com/qsl`
 2. Enters their callsign
 3. Selects the QSO(s) they want to print on the card or certificate
 4. Requests the print
-5. Saves the PDF to their computer (or prints it directly)
+5. QSL card is displayed. Save or print as desired.
 
 # Printing QSOs on the template
 Smooth QSO uses ImageMagick to "draw" text on top of the QSL template

 with installation-related questions insofar as they deal with unclear
 directions or bugs on particular platforms but I will not help with
 general installation and configuration of a webserver, PHP, MySQL, etc.
