-# Polyline Algorithm for .NET (.NET Standard 2.1)
+# PolylineAlgorithm.Abstraction
 
-Lightweight .NET Standard 2.1 library implementing Google Encoded Polyline Algorithm.
-It provides types and methods for encoding and decoding polylines.

+Lightweight .NET Standard 2.1 library implementing Google Encoded Polyline Algorithm.
+Package should be primarily used as baseline for libraries that implement polyline encoding/decoding functionality.
 
 More info about the algorithm can be found at [Google Developers](https://developers.google.com/maps/documentation/utilities/polylinealgorithm).
 
 ## Prerequisites
 
-.NET Polyline Algorithm is avalable as a NuGet package targeting .NET Standard 2.1.
+PolylineAlgorithm.Abstraction is available as a NuGet package targeting .NET Standard 2.1.
+
+.NET CLI: `dotnet add package PolylineAlgorithm.Abstraction`
+
+Package Manager Console: `Install-Package PolylineAlgorithm.Abstraction`
 
-.NET CLI: `dotnet add package PolylineAlgorithm`
+## How to use it
 
-Package Manager Console: `Install-Package PolylineAlgorithm`
+In the majority of cases you would like to inherit `AbstractPolylineDecoder<TPolyline, TCoordinate>` and `AbstractPolylineEncoder<TCoordinate, TPolyline>` classes and implement abstract methods that are mainly responsible for extracting data from your coordinate and polyline types and creating new instances of them.
 
-## Hot to use it
+In some cases you may want to implement your own decoder and encoder from scratch.
+In that case you can use `PolylineEncoding` static class that offers static methods for encoding and decoding polylines segments.
