+## Development
+
+First iteration was written in vanilla Javascript as a proof of concept.
+It was then refactored to use [React](https://reactjs.org/) (because I wanted
+to learn it and play around) with [`create-react-app`](https://github.com/facebook/create-react-app).
+
+Local development is straightforward:
+
+```
+git clone https://github.com/gobbledygook88/knowing-lu.git
+cd knowing-lu
+npm install
+npm start
+```
+
+The online version is hosted on Github Pages and deployed with [`gh-pages`](https://github.com/tschaub/gh-pages).
+
+### Testing
+
+Testing is currently in its infancy; they will be written soon.
+
+## Roadmap
+
+Here are a list of features which are nice to have:
+
+* Current progress for each line and zone
+* Acheivement badges, e.g. one for each line and zone
+* Panning to last correct station (this is in the works, but not yet working correctly)
+* Storage of state to some cloud service for cross-device use
+* Statistics - local and global
