+Open Asset Import Library Coding Conventions
+==
+
+If you want to participate as a developer in the **Open Asset Import Library** please read and respect the following coding conventions. This will ensure consistency throughout the codebase and help all the Open Asset Import Library users.
+
+Spacing
+==
+
+* No spaces between parentheses and arguments - i.e. ```foo(bar)```, not ```foo( bar )```
+
+Tabs
+--
+
+The tab width shall be 4 spaces.  Use spaces instead of tabs.
+
+Class/Struct Initialization
+==
+Constructors shall use initializer lists as follows:
+```cpp
+SomeClass()
+    : mExists(false)
+    , mCounter()
+    , mPtr()
+{}
+```
+
+* Initializations are one-per-line
+* Commas go at the beginning of the line rather than the end
+* The order of the list must match the order of declaration in the class
+* Any member with a default value should leave out the optional *NULL* or *0* - e.g. ```foo()```, not ```foo(NULL)```
