 Here are some of the advantages of SheenFigure.
 
-* Object based.
-* Designed to be thread safe.
-* Lightweight API for interaction.
-* Clear differentiation of public and private API.
-* Thoroughly tested.

 ## Dependency
-SheenFigure only depends on SheenBidi in order to support UTF-8, UTF-16 and UTF-32 string encodings. Other than that, it only uses standard C library headers ```stddef.h```, ```stdint.h```, ```stdlib.h``` and  ```string.h```.

 ## Configuration

 * ```SF_CONFIG_UNITY``` builds the library as a single module and lets the compiler make decisions to inline functions.
 
 ## Compiling
 SheenFigure can be compiled with any C compiler. The best way for compiling is to add all the files in an IDE and hit build. The only thing to consider however is that if ```SF_CONFIG_UNITY``` is enabled then only ```Source/SheenFigure.c``` should be compiled.

+## Conformance
+Following are the tables implemented by SheenFigure.
