-phpLDAPadmin
-============
+# phpLDAPadmin
+phpLDAPadmin is a web based LDAP data management tool for system administrators. It is commonly known and referred by many as "PLA".
 
-phpLDAPadmin - Web based LDAP administration tool
+A primary goal of PLA is to be as intuitive as possible - so it is certainly possible for end users to use it as well, for example, to manage their data in an LDAP server.
 
+PLA is designed to be compliant with LDAP RFCs, enabling it to be used with any LDAP server.
+If you come across an LDAP server, where PLA exhibits problems, please open an issue with full details of the problem so that we can have it fixed.
+
+## History
+Initially created in 2002 by David Smith, it was taken over by Deon George (aka leenooks) in 2005.
+
+Since 2003 many things have changed - initial development was done in CVS and the project was hosted on Sourceforge.
+In 2009, CVS was swapped out for GIT, and in around 2011 the project was moved to Github.
+
+The PLA v1.2.x stream was created in July 2009.
+
+Work on PLA v2 has started and some information on that is below. Soon `master` will be updated and `BRANCH-2.0` will be visible in git. Until then, a sneak peak of v2 is available [here](https://phpldapadmin.servio.leenooks.net)
+
+## THANK YOU
+Over the years, many, many, many people have supported PLA with either their time, their coding or with financial donations.
+I have tried to send an email to acknowledge each contribution, and if you havent seen anything personally from me, I am sorry, but please know that I do appreciate all the help I get, in whatever form it is provided.
+
+Again, Thank You.
+
+## Future
+Web development, tools, approaches and technology has come along way since 2009 and some talented folks have created some fantastic tools.
+With that PLA is going under a major revamp in preparation for v2 and will aim to use those existing creations to help speed up the revamp effort.
+
+Some of the creations planned to be used in v2 include:
+* Laravel (https://laravel.com)
+* adldap2/adldap2 (https://github.com/Adldap2/Adldap2)
+* JQuery (https://jquery.com)
+* FancyTree (https://github.com/mar10/fancytree)
+* ArchitectUI (https://architectui.com)
+
+PLA v1.2.x will be archived into [BRANCH-1.2](https://github.com/leenooks/phpLDAPadmin/tree/BRANCH-1.2), and `master` will be changed to reflect the new v2 work and effort.
+
+If you plan to use PLA, and cannot use an installation from your OS package, please use [BRANCH-1.2](https://github.com/leenooks/phpLDAPadmin/tree/BRANCH-1.2) while progress is made in master for v2.
+
+If you like the cutting edge, feel free to try out `master`, but expect problems, bugs and missing functionality.
+If you have extended v2 and would like to contribute your extension, or if you find a way to fix something that is broken or missing please submit a pull request.
+
+Alternatively, you can get take a peek at the work so far by using our docker container, which is built automatically after testing passes.
+The [demo](http://demo.phpldapadmin.org) site, will also be running the same docker container. (See below for details.)
+
+In summary, for the time being, expect `master` to be buggy and broken, and I'll update this readme as enhancements progress.
 
 ## Installation
+The following instructions will be for PLA v2 when its commited to GIT. Checkback regularly, as it will be pushed when its is semi functional.
 
-[INSTALL](INSTALL.md)
+### Installation on your server
+
+#### Prerequisites
+* A HTTP server (eg: Apache, Nginx)
+* PHP (minimum version 7.2) https://www.php.net
+* Composer https://getcomposer.org
+* GIT
+
+#### Installation
+1. Checkout the code from github
+   ```bash
+   git clone https://github.com/leenooks/phpLDAPadmin.git
+   ```
+
+1. Install composer dependencies.
+   ```bash
+   composer install
+   ```
+
+1. Edit your `.env` file as appropriate
+
+   copy `.env.example` to `.env` as a start.
+
+1. Configure your webserver to have PLA's root in the `public` directory
+
+### Using Docker
+Instructions to come.
+
+## Getting Help
+The best place to get help with PLA (new and old) is on Stack Overflow (https://stackoverflow.com/tags/phpldapadmin/info)
+
+## Found a bug?
+If you have found a bug, and can provide detailed instructions so that it can be reproduced, please open an [issue](https://github.com/leenooks/phpLDAPadmin/issues) and provide those details.
+
+Before opening a ticket, please check to see if it hasnt already been reported, and if it has, please provide any additional information that will help it be fixed.
+
+*TIP*: Issues opened with reproducible details accompanied with a patch (or a pull request) to fix the problem will be looked at first.
