 It supports/implements:
 - Deslauriers-Dubuc 13/7 and CDF 5/3, wavelets.
-- Configurable quality loss ([examples](#examples) below).
+- Configurable quality loss ([showcase](#showcase) below).
 - 8 bits per component. 4 channels.
 - Reversible YCoCg color transformation.
 - Elias coding + Rle compression. Nonetheless can handle ratios of 1:12 before artifacts became visible.
 - Good performance. There is care on cache and memory usage.
-- Everything is done with integers. Ensure always identical outputs (even in lossy compression) and provides gain in performance.
+- Everything is done with integers, ensuring always identical outputs (even in lossy compression).
 
 And in an experimental state:
 - Lossless compression.
