@@ -6,85 +6,72 @@ something else like a webserver, git-server, cloud platform, programming
 workstation, etc.  Therefore, only a few core files applicable to nearly every
 conceivable installation are included here.
 
+This archive and included script are meant to supplement my article on setting
+up a Debian base-system found at https://mytechiethoughts.com/<post_address>
+
 ## Included files
 
-### bash template files
+Please refer to the readme.md in each subdirectory for a list and description of
+each included file.
 
-#### bash.rc
+## The script file (customize.sh)
 
-Included are *.bashrc* files for both new users (in the */etc/skel/* directory)
+The included script file copies all the files in this archive to the proper
-and the root user.  These files are the Debian default files.  They are included
+locations on a default Debian system.  It makes backups of your existing files
-and copied so that user profiles start out at baseline settings and pull all
+in-place with the extension *.original*.  This simply saves you time and
-initial customizations from */etc/bash.bashrc*.  Users are free to alter their
+possible errors copying the files manually.  The structure of this archive
-*.bashrc* as they see fit and those settings will override or add to the ones
+exactly mirrors a default Debian installation, so you can use that as a guide if
-I've included in */etc/bash.bashrc*
+you choose not to use the script.
 
-#### profile
+### Running the script
 
-This is the Debian default *profile* and is copied to */etc/profile* to return
+Please note you must either make the script executable or call it explicitly via
-the system to a baseline configuration.  Again, this is done to ensure that only
+BASH.  In the latter case, you'd run the script as follows:
-*/etc/bash.bashrc* is providing initial customizations to users.
 
-#### bash.bashrc
+```bash
+/bin/bash ./customize.sh
+```
 
-Of the bash customization files, this is the only one that is NOT in a default
+If you want to make the script executable:
-configuration. I have added the following customizations I find useful
-especially for new users and system admins:
 
-- colourized directory listings with built-in automatic colour settings
+```bash
-- changed prompt to include 24-hour clock, username, hostname and current
+chmod +x customize.sh
-  directory display
+./customize.sh
-  - username changes to RED when working as ROOT (uid=0)
+```
-- added the following command aliases
-  
-  alias|full command|explanation
-  ---|---|---
-  ll|ls -l|default 'ls' output
-  l|ls -lAsh --group-directories-first|far more useful and robust file display including sizes, permissions and owners
-  rm|rm -i|confirmation prompt when deleting file
-  mv|mv -i|confirmation prompt when moving file would result in overwriting existing file
-  cp|cp -i|confirmation prompt when copying file would result in overwriting existing file
 
-### nano defaults (nanorc)
+Due to location of the files being replaced, **you MUST run this script as ROOT**
+(the script will exit if you run as a different user) or run it via sudo like
+this (assuming you made it executable):
 
-The following options have been enabled/set in nano to provide what I feel is an
+```bash
-easier editing experience especially for people coming from a Windows background
+sudo ./customize.sh
-and new users/admins.
+```
 
-- 'rebind' numeric keypad to fix problems with using keypad with some SSH clients
+### Passing a custom path to the script
-- set 'smart home' some home key is useful
-- allow opening multiple files at once
-- always display line numbers
-- constantly display cursor position at the bottom of the screen
-- set vim lock-files
-- autoindent ON, tab-size of 4 spaces
-- convert tabs to spaces
-- turn off hard line wrapping
-- turn ON soft line wrapping for ease of readability
-- closing 'brackets' (for alignment purposes) set as: "')>]}
-- cut to end of line by default
-- set proper bracket matching (ie. "<" matches ">", etc.)
-- turned on default colours so nano doesn't look so drab
-- added the following key-bindings
 
-binding|fuction
+If you want to test out the script before having it update your actual system
----|---
+configuration, you can supply an alternate destination path.  This is referred
-alt-c/alt-C|copy selected text
+to as a 'Base Path' by the script and it will show a warning if this option is
-alt-x/alt-X|cut selected text
+used.  Please note, your 'Base Path' MUST have the same directory structure as
-alt-v/alt-V|paste text on clipboard
+an actual system, so the expected directories must already exist or the script
+will just throw errors and not actually copy files.
 
-### time syncronization settings (timesyncd.conf)
+Let's assume you wanted to test the script and copy files to */testdir*.  You
+would do the following prepare the directory with the expected structure:
 
-This file configures *systemd-timesyncd.service* and allows for very simple
+```bash
-NTP-sync setup.  Simply edit the **NTP=* to list your desired timeservers,
+mkdir -p /testdir/root
-each separated by a single space.  In the event those timeservers are not
+mkdir -p /testdir/etc/{skel,ssh,systemd}
-available, you can configure back servers by listing them on the
+```
-**FallbackNTP=** line, again space delimited.
 
-I've set the default in this file to be the worldwide NTP.org servers.  This
+Then you could invoke the script as follows:
-should work for pretty much anyone that uses this file, but you really should
-customize the list to use geographically closer timeservers or the timeserver on
-your LAN, etc.
 
-### SSH server configuration (sshd_config)
+```bash
+customize.sh /testdir
+```
 
+The script would then copy all files into */testdir* while mirroring the
+structure of a live system beneath that.  Again, this is useful only for testing
+and will NOT update your actual system!
