-- Modify/Add manifest files for test classes (for execution) and for Apex(source) classes (for code coverage computation) in the following location in your project setup: src/main/resources
+- There are two ways in which user can select the list of tests to execute and the lsit of classes to examine the code coverage
+  - regex - identify and provide regex for the test class names that you want to execute for the "-regex.for.selecting.test.classes.to.execute" parameter. Example: if you want to execute the tests: My_Apex_controller_Test, My_Apex_builder_Test and My_Apex_validator_Test, identify the regex as "My_Apex_\*_Test". Pass the parameter "-regex.for.selecting.test.classes.to.execute My_Apex_\*_Test" while executing the mvn command.
+    - Similarly, you can provide regex for the classes for which you want to examine the code coverage by using "-regex.for.selecting.source.classes.for.code.coverage.computation My_Apex_\*_Class" while executing the mvn command.
+  - Manifest files - List of tests can be read from Manifest files. Create a manifest file say ManifestFile_Unit_Tests.txt in "src/main/resources" location of your project. Add test names to execute in the manifest file. Specify this manifest file as "-manifest.files.with.test.class.names.to.execute ManifestFile_Unit_Tests.txt" while executing the mvn command. 
+    - Similarly, add the class names for which you want to exercise code coverage in a manifest file say ClasssManifestFile.txt in "src/main/resources" location of your project and Specify this manifest file as "-manifest.files.with.source.class.names.for.code.coverage.computation ClassManifestFile.txt" while executing the mvn command. 
+  - Note that multiple regexes and manifest files can be specified using comma seperation(without spaces). Example: "-regex.for.selecting.test.classes.to.execute This_Is_Regex1\*,\*Few_Test,Another_\*_regex -manifest.files.with.source.class.names.for.code.coverage.computation ClassManifestFile.txt,MoreClassesManifestFile.txt"
