+web-sharelatex uses [Grunt](http://gruntjs.com/) to build its front-end related assets.
+
+Image processing tasks are commented out in the gruntfile and the needed packages aren't presently in the project's `package.json`. If the images need to be processed again (minified and sprited), start by fetching the packages (`npm install grunt-contrib-imagemin grunt-sprity`), then *decomment* the tasks in `Gruntfile.coffee`. After this, the tasks can be called (explicitly, via `grunt imagemin` and `grunt sprity`).
