Removed the line `SHELL:=/usr/bin/env bash'. Most BSDs don't ship bash in the
base system by default and the build doesn't need it anyway.

Also added some more version statements to define useXDG for the other BSDs.

 D-Scanner is a tool for analyzing D source code
 
 ### Building and installing
-First make sure that you have all the source code. Run ```git submodule update --init --recursive```
+
+First, make sure that you have fetched the upstream: git@github.com:dlang-community/D-Scanner.git
+
+```
+git remote add upstream git@github.com:dlang-community/D-Scanner.git
+git fetch upstream
+```
+
+Secondly, make sure that you have all the source code. Run ```git submodule update --init --recursive```
 after cloning the project.
 
 To build D-Scanner, run ```make``` (or the build.bat file on Windows).

+Remove the check regarding structs with no arguments constructors.
+
+The check is implemented in constructors.d and it warns against the usage
+of both constructors with all parameters with default values and constructors
+without any arguments, as this might be confusing. This scenario, for structs,
+is no longer D valid code and that's why it is being deprecated.
+
+Let's consider the following code:
+
+---
+struct Dog
+{
+	this() {}
+	this(string name = "doggie") {} // [warn]: This struct constructor can never be called with its default argument.
+}
+---
+
+D-Scanner would throw and error for this particular struct, but this code
+does not compile anymore hence this check is not needed anymore/
