 # LCSTorch
 
 Longest Common Subsequence (LCS) extension for PyTorch tensors
+
+## TODOs
+
+* batch methods, i.e. supporting 2D arrays;
+* batch methods with any number of dimensions (nD array) and add a `dim` argument;
+* make it work with an unlimited number of sequences, and set `dim` and `pad_token` as kwargs only;
