Yes, you’re correct. You can also separate the instruction to field-based so it will have something like the instruction (using the standard content editor), growth time (text/number field), type of soil (text/select field), etc. That way, it will be more organized.
The post object field documentation has an example on how you add it in your template file. But you need to add it to the right files. If you want to show it on your post page, you need to add the code in the single.php file. This page should give you more idea about it: https://codex.wordpress.org/Templates.
I hope this helps 🙂
