-# DebianConfigs
+# My standard configuration files for Debian and basic services
+
+This is a collection of several configuration files that I use when setting up a
+BASIC bare-bones Debian system.  Quite often, such a system will become
+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.
+
+## Included files
+
+### bash template files
+
+#### bash.rc
+
+Included are *.bashrc* files for both new users (in the */etc/skel/* directory)
+and the root user.  These files are the Debian default files.  They are included
+and copied so that user profiles start out at baseline settings and pull all
+initial customizations from */etc/bash.bashrc*.  Users are free to alter their
+*.bashrc* as they see fit and those settings will override or add to the ones
+I've included in */etc/bash.bashrc*
+
+#### profile
+
+This is the Debian default *profile* and is copied to */etc/profile* to return
+the system to a baseline configuration.  Again, this is done to ensure that only
+*/etc/bash.bashrc* is providing initial customizations to users.
+
+#### bash.bashrc
+
+Of the bash customization files, this is the only one that is NOT in a default
+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
+- changed prompt to include 24-hour clock, username, hostname and current
+  directory display
+  - 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)
+
+The following options have been enabled/set in nano to provide what I feel is an
+easier editing experience especially for people coming from a Windows background
+and new users/admins.
+
+- 'rebind' numeric keypad to fix problems with using keypad with some SSH clients
+- 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
+---|---
+alt-c/alt-C|copy selected text
+alt-x/alt-X|cut selected text
+alt-v/alt-V|paste text on clipboard
+
+### time syncronization settings (timesyncd.conf)
+
+This file configures *systemd-timesyncd.service* and allows for very simple
+NTP-sync setup.  Simply edit the **NTP=* to list your desired timeservers,
+each separated by a single space.  In the event those timeservers are not
+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
+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)
