+============
+
+## Building
+
+See `README.md` for instructions on how to build. Build is done with
+`webpack`.
+
+
+## Useful scripts
+
+A few `npm` scripts are provided:
+* `npm run build` to trigger a dev build.
+* `npm run watch` to trigger a dev build and rebuild on changes.
+* `npm run prod` to trigger a production build.
+* `npm run clean` to clean the `app/dist` folder.
+* `npm run extractTranslations` to generate a translation file (see below).
+
+
+## Translating
+
+Translations are handled by [react-intl](https://github.com/yahoo/react-intl/).
+
+`npm run extractTranslations` output a file containing all the english
+translations, in the expected form. It is a mapping of ids and strings to
+translate, with an extra description provided as a comment at the end of the
+line, for some translation context.
+
+Typically, if you want to translate to another `$LOCALE` (say `fr-FR`), create
+a folder `./app/locales/$LOCALE`, put inside the generated file from `npm run
+extractTranslations`, called `index.js`. Copy the lines in
+`./app/locales/index.js` to include your new translation and translate all the
+strings in the `./app/locales/$LOCALE/index.js` file you have just created.

 before comitting, as commit should always contain an up to date production
 build.
 
+Compilation cache is stored in `.cache` at the root of this repo. Remember to
