+Got stuck?  Worry not!  Chances are other users have encountered
+the exact same problem as you have, brought it up for
+[discussion](http://discuss.gohugo.io/), and have likely found a solution
+through the collective wisdom of our vibrant Hugo community!
+
+Here are some examples:
+
+* [`hugo new` aborts with cryptic EOF error](/troubleshooting/strange-eof-error/) (affects v0.12 and lower)
+* [Categories with accented characters inaccessible](/troubleshooting/categories-with-accented-characters/) (affects Mac OS X users)
+* [My CSS files aren't loaded!](http://discuss.gohugo.io/t/deployment-workflow/90/15)
+* [How do I include an image gallery on my website?](http://discuss.gohugo.io/t/image-gallery/594)
+* ... And a lot more!
+
+Indeed, you may find many questions and solutions
+to problems in our [discussion forum](http://discuss.gohugo.io/),
+and you may find the [support](http://discuss.gohugo.io/category/support)
+and [tips & tricks](http://discuss.gohugo.io/category/tips-tricks)
+categories particularly helpful.
+
+Can't find anything?  Please write on the forum and post your questions
+and comments!  Sometimes, your feedback may lead to the discovery of
+existing bugs in the code or in the documentation, and may even spur
+the interest of adding new features to the next Hugo version, improving
+Hugo for everybody!  (Thank you!)  See you on the forum!
