+# Haskell client for Yoti
+
+Haskell client https://yoti.com
+
+
+## Integration
+
+### With Elm
+
+### With PureScript
+
+## Testing
+
+### Basic functionality
+
+### Servant Integration
+
+Test folder contains minimalistic servant app that handled all Yoti related methods, as an example of Yoti Haskell SDK integrated into web service.
+
+To run, move to `test/servant`, build app
+
+```
+stack build
+```
+
+and run with
+
+```
+stack exec -- yoti-servant-api -p 3000 -d
+```
+
+open `index.html` and it will handle localhost redirections when you used Yoti mobile application for verification
