+
+- :code:`./gulpfile.js` with Gulp tasks defined;
+- :code:`./{{ cookiecutter.project_slug }}/static/build/` (build directory) with static assets built via Gulp.
+
+Let us take a closer look at :code:`./gulpfile.js`:
+
+- paths to static assets are provided by :code:`pathsConfig()`;
+- for clarity, related tasks are grouped by :code:`region`:
+    - :code:`images`:
+        - :code:`images`: run image-related tasks in parallel, namely:
+            - :code:`favicons-images`: process favicon images only;
+            - :code:`nonfavicons-images`: process all images except for favicons.
+    - :code:`scripts`:
+        - :code:`scripts`: run script-related tasks in sequence, namely:
+            - :code:`js-scripts`: process js scripts.
+    - :code:`styles`:
+        - :code:`styles`: run script-related tasks in sequence, namely:
+            - :code:`sass-styles`: process SCSS styles;
+            - :code:`css-styles`: process CSS styles.
+    - :code:`build`:
+        - :code:`build`: run :code:`images`, :code:`scripts`, and :code:`styles` in parallel;
+        - :code:`clean-build`: clean up build directory:
+- the :code:`default` task runs the following ones in sequence:
+    - :code:`build`;
+    - :code:`init-browserSync`: initialize `BrowserSync`_;
+    - :code:`watch`: watch static asset files/directories changes, running BrowserSync on any changes.
+
+.. _`BrowserSync`: https://www.browsersync.io/

+Workflow
+--------
+
+#. [*skip if done*] :ref:`devlocdocker-build-the-stack`;
+#. :ref:`devlocdocker-boot-the-system`.
+
+By default, :code:`gulp` command gets executed immediately after :code:`node`
+container startup (see :code:`./dev.yml` for details) which in turn invokes
+the :code:`default` task, so generally one would not need to run any
+of the aforementioned tasks manually. However, should the need arise,
+oftentimes just a few of the tasks listed above will be used to, for instance,
+straightforwardly :code:`build` all assets
+

+
+or build :code:`scripts` selectively
