This is the second part of a very popular post, Helm from basics to advanced. In the previous post (we highly suggest you read it, if you haven’t done so already) we covered Helm’s basics, and finished with an examination of design principles. In this post, we’d like to continue our discussion of Helm by exploring best practices and taking a look at some common mistakes. Before we start, if you really want to get deep down into the nitty gritty of Helm, I suggest you to read the official guide to creating templates.
