 # Local sequence alignment in JS
-This simple implementation makes an alignment between two strings, and it is the core of the application found here: https://github.com/Gagniuc/Jupiter-Bioinformatics-V2-normal
+
+This JavaScript implementation detects the areas where two DNA/RNA/protein sequences are similar to each other. In fact, this simple implementation makes an alignment between any two strings. All symbols from UTF-8 are accepted by this algorithm. Moreover, the implementation is the core of the application found here: https://github.com/Gagniuc/Jupiter-Bioinformatics-V2-normal
