+Profile based segregation
+====================
+
+We are using maven build profiles to segregate the huge list of individual projects we have in our repository.
+
+The projects are broadly divided into 3 list: first, second and heavy. 
+
+Next, they are segregated further on the basis of tests that we want to execute.
+
+Therefore, we have a total of 6 profiles:
+
+| Profile                 | Includes                    | Type of test enabled |
+| ----------------------- | --------------------------- | -------------------- |
+| default-first           | First set of projects       | *UnitTest            |
+| integration-lite-first  | First set of projects       | *IntegrationTest     |
+| default-second          | Second set of projects      | *UnitTest            |
+| integration-lite-second | Second set of projects      | *IntegrationTest     |
+| default-heavy           | Heavy/long running projects | *UnitTest            |
+| integration-heavy       | Heavy/long running projects | *IntegrationTest     |
 
 Building the project
 ====================
-To do the full build, do: `mvn clean install`
+
+Though it should not be needed often to build the entire repository at once because we are usually concerned with a specific module.
+
+But if we want to, we can invoke the below command from the root of the repository if we want to build the entire repository with only Unit Tests enabled:
+
+`mvn clean install -Pdefault-first,default-second,default-heavy`
+
+or if we want to build the entire repository with Integration Tests enabled, we can do:
+
+`mvn clean install -Pintegration-lite-first,integration-lite-second,integration-heavy`

 Running Tests
 =============
-The command `mvn clean install` will run the unit tests in a module.
-To run the integration tests, use the command `mvn clean install -Pintegration-lite-first`
+The command `mvn clean install` from within a module will run the unit tests in that module.
+For Spring modules this will also run the `SpringContextTest` if present.
+
+To run the integration tests, use the command:
+
+`mvn clean install -Pintegration-lite-first` or 
+
+`mvn clean install -Pintegration-lite-second` or 
+
+`mvn clean install -Pintegration-heavy`

+We've all heard the scare stories about North Korea: the homemade nuclear arsenal built while their people starve and then aimed imprecisely at the rest of the world, a 
+leader so deluded he makes L Ron Hubbard look like a man excessively overburdened with self-doubt and their deep-seated belief that foreign capitalists will invade at any 
+moment and steal all their bauxite.
+The popular portrayal of this Marxist nation is something like one of the more harrowing episodes of M*A*S*H, only with the cast of wacky characters replaced by twitchy, 
+heavily armed Stalinist meth addicts
+Cracked would like to take a moment to celebrate the good things about North Korea though, the things that the country's enemies prefer to suppress as part of their politically 
+motivated jealousy. Like how no different to you and me, there's nothing every North Korean likes more after an 18 hour shift at the phosphorus plant than a nice beer to go with 
+his dried fish ration. Ever attentive to its people's needs and in the twinkling of a decade, North Korea's leadership bought, disassembled, transported and rebuilt a British 
+brewery in order to discover and reproduce the secrets of beer and then brew the sweet nectar for its hardworking people, up to 18 bottles at a time. And with minimal fatalities. 
+When was the last time YOUR leader got a beer for YOU, American? (NB do not answer this question if you are Henry Louis Gates).
+Or how about the fried chicken restaurant that downtown Pyongyang boasts? Yes real chicken, fried and then delivered to your sleeping cube, with optional beer if you like! You 
+don't even have to remove the feathers or pull out the gizzard yourself. Mostly. Americans must eat their fried chicken from a bucket, like swine, sold by a company so secretive 
+that even the very blend of seasoning used is intentionally kept from them. And they call North Korea paranoid?
+And how many nations would entertain the syphilitic, bourgeois ramblings of Bill Clinton let alone permit him anywhere near their proud womenfolk? Only wise Kim Jong Il could see 
+past Bill's many, many imperfections and treat him with the pity and kindness he deserves, accepting his feeble pleas to pardon the American spies rightly convicted of photographing 
+the nation's sensitive beetroot fields.

-CAS Overlay Template
-============================
-
-Generic CAS WAR overlay to exercise the latest versions of CAS. This overlay could be freely used as a starting template for local CAS war overlays. The CAS services management overlay is available [here](https://github.com/apereo/cas-services-management-overlay).
-
-# Versions
-
-```xml
-<cas.version>5.3.x</cas.version>
-```
-
-# Requirements
-
-* JDK 1.8+
-
-# Configuration
-
-The `etc` directory contains the configuration files and directories that need to be copied to `/etc/cas/config`.
-
-# Build
-
-To see what commands are available to the build script, run:
-
-```bash
-./build.sh help
-```
-
-To package the final web application, run:
-
-```bash
-./build.sh package
-```
-
-To update `SNAPSHOT` versions run:
-
-```bash
-./build.sh package -U
-```
-
-# Deployment
-
-- Create a keystore file `thekeystore` under `/etc/cas`. Use the password `changeit` for both the keystore and the key/certificate entries.
-- Ensure the keystore is loaded up with keys and certificates of the server.
-
-On a successful deployment via the following methods, CAS will be available at:
-
-* `http://cas.server.name:8080/cas`
-* `https://cas.server.name:8443/cas`
-
-## Executable WAR
-
-Run the CAS web application as an executable WAR.
-
-```bash
-./build.sh run
-```
-
-## Spring Boot
-
-Run the CAS web application as an executable WAR via Spring Boot. This is most useful during development and testing.
-
-```bash
-./build.sh bootrun
-```
-
-### Warning!
-
-Be careful with this method of deployment. `bootRun` is not designed to work with already executable WAR artifacts such that CAS server web application. YMMV. Today, uses of this mode ONLY work when there is **NO OTHER** dependency added to the build script and the `cas-server-webapp` is the only present module. See [this issue](https://github.com/spring-projects/spring-boot/issues/8320) for more info.
-
-
-## Spring Boot App Server Selection
-
-There is an app.server property in the `pom.xml` that can be used to select a spring boot application server.
-It defaults to `-tomcat` but `-jetty` and `-undertow` are supported.
-
-It can also be set to an empty value (nothing) if you want to deploy CAS to an external application server of your choice.
-
-```xml
-<app.server>-tomcat<app.server>
-```
-
-## Windows Build
-
-If you are building on windows, try `build.cmd` instead of `build.sh`. Arguments are similar but for usage, run:
-
-```
-build.cmd help
-```
-
-## External
-
-Deploy resultant `target/cas.war`  to a servlet container of choice.
-
-
-## Command Line Shell
-
-Invokes the CAS Command Line Shell. For a list of commands either use no arguments or use `-h`. To enter the interactive shell use `-sh`.
-
-```bash
-./build.sh cli
-```
