-# Aline-rs 
+<https://webdocs.cs.ualberta.ca/~kondrak/>
+Copyright 2002 by Grzegorz Kondrak.
 
-This is a Aline implementation based on the python nltk implementation.
+ALINE is an algorithm for aligning phonetic sequences, described in \[1\].
+This module is a port of Kondrak's (2002) ALINE. It provides functions for
+phonetic sequence alignment and similarity analysis. These are useful in
+historical linguistics, sociolinguistics and synchronic phonology.
 
+ALINE has parameters that can be tuned for desired output. These parameters are:
+- C_skip, C_sub, C_exp, C_vwl
+- Salience weights
+- Segmental features
+
+In this implementation, some parameters have been changed from their default
+values as described in \[1\], in order to replicate published results. All changes
+are noted in comments.
+
+## Get optimal alignment of two phonetic sequences
+
+```
+use aline::align;
+
+let alignment = align("θin", "tenwis", 0.0);
+
+assert_eq!(
+    alignment,
+    vec![
+        vec![
+            ("θ", "t"),
+            ("i", "e"),
+            ("n", "n")
+        ].iter()
+        .map(|(a, b)| (a.to_string(), b.to_string()))
+        .collect::<Vec<(String, String)>>()
+    ]
+);
+```
