Hi Krux02, I have updated the README to provide more explanation of the role of succinct data structures.
Notice that the library is not really about text. Think of strings as long sequences of symbols from a finite (small) alphabet. The prototypical example would be the genome as a string of A, C, T, G. Other examples are time series, when they are restricted to a finite alphabet by rounding to a few values (such as low, medium or high)
