Liquid Hello World read template from file

---

• Templates are usually much biggger than what we had in the first example.
• We usually prefer to keep the templates as an external files.
• Instead of parse we can use parse_file to load the template from an external file.
• This happens at run-time so you will need to supply the templates outside of the binary or the user will need to create the templates.
