+This theme uses libsass/gulp to process the sass/*.scss. Never edit any of the .css files manually.
+
+#### Editing the theme
+
+* Install `nvm` (https://github.com/creationix/nvm)
+
+* Run `nvm i` from the directory containing `.nvmrc`
+
+* Run `npm i` from the directory containing `gulpfile.js`. It's the same directory as the one that contains `.nvmrc` in this case.
+
+* Install `gulp` with `npm i -g gulp`
+
+* Edit the sass/*.scss files
+
+* Regenerate the .css files by executing `gulp` from the directory that contains `gulpfile.js`
+
+--
+
+#### Editing the images in the `assets` folder
+
+* Open the `assets.svg` file in inkscape. Each object in the .svg file corresponds to an image in the `assets` folder.
+
+* Find the object you want to edit and make your changes. Important: Don't change the obejct id.
+
+* Save `assets.svg` and delete the images corresponding to the edited .svg objects from the `assets` folder (or just delete everything in the `assets` folder).
+
+* Run `./render-assets.sh` from a terminal.
