+## Technical Limitations
 
 - Each spritesheet is 4096x4096 maximum, which is a size of 4K Texture. However it is recommended to be smaller or equal to 1024x1024.
 - Glyphs exceeding 15px of width needs to be broken down with 2 or more characters. Wider sheets WILL NOT BE IMPLEMENTED, can't waste much pixels just for few superwide glyphs.
 - Due to how the compiler is coded, actual glyph must have alpha value of 255, the tags must have alpha values LESS THAN 255 (and obviously greater than zero). RGB plane of the TGA image doesn't do anything, keep it as #FFFFFF white.

 On this font, Hangul letters are printed by assemblying two or three letter pieces. There are 10 sets of Hangul letter pieces on the font. Top 6 are initials, middle 2 are medials, and bottom 2 are finals. On the rightmost side, there's eight assembled glyphs to help you with (assuming you have basic knowledge on the writing system). Top 6 tells you how to use 6 initials, and bottom 2 tells you how to use 2 finals.

-#### Little notes
-- To display Bulgarian/Serbian variants, you need special Control Characters. (GameFontBase.charsetOverrideBulgarian -- U+FFFC1; GameFontBase.charsetOverrideSerbian -- U+FFFC2)
-- All Han characters are in Chinese variant, no other variants are to be supported as most Chinese, Japanese and Korean people can understand other's variant and as long as I can, we don't bother anyway.
-- Indian script in general is not perfect: right now this font will never do the proper ligatures (I can't draw all the 1 224 possible combinations). Hopefully it's still be able to understand without them.
+#### Notes and Limitations
+- Displaying Bulgarian/Serbian variants of Cyrillic requires special Control Characters. (`GameFontBase.charsetOverrideBulgarian` -- U+FFFC1; `GameFontBase.charsetOverrideSerbian` -- U+FFFC2)
+- All Han characters are in Mainland Chinese variant. There is no plan to support the other variants unless there is someone willing to do the drawing of the characters
+- Only the Devanagari and Tamil has full (as much as I can) ligature support for Indic scripts -- Bengali script does not have any ligature support
 - Slick2d versions are now unsupported. I couldn't extend myself to work on both versions, but I'm still welcome to merge your pull requests.

 ### How to Use Color Code
 
 Color codes are individual unicode characters. While you can somehow make a raw character and paste in on your code, it's certainly not desirable. Fortunately, we're also providing utility functions for the color codes.

+विकिपीडिया सभी विषयों पर प्रामाणिक और उपयोग, परिवर्तन
+व पुनर्वितरण के लिए स्वतन्त्र ज्ञानकोश बनाने का एक बहुभाषीय
+प्रकल्प है। यह यथासम्भव निष्पक्ष दृष्टिकोण वाली सूचना प्रसारित
+करने के लिए कृतसंकल्प है। सर्वप्रथम अंग्रेज़ी विकिपीडिया
+जनवरी 2001 में आरम्भ किया गया था, और हिन्दी
+विकिपीडिया का शुभारम्भ जुलाई 2003 में हुआ। सहायता पृष्ठ

+किसी लेख को कैसे परिवर्तित कर सकते हैं।
