I'm frustrated already and I haven't even bought a template. The advice to hire a freelancer is a cop out. Charlie4282 asked if he could use Dreamweaver. Unified never answered, saying simply you don't need Dreamweaver, you could use notepad, or hire a freelancer. There are hundreds of comments from people who don't understand how to work with the templates. This is like an echo chamber that is NOT helping Envato expand the marketplace for its otherwise very appealing products. I use Dreamweaver myself because I can produce a website without knowing any coding at all. But I can't figure out what products templates will work in this software or not. I'd suggest that Envato devote some time to developing a Q&A section addressing the unknowns facing the non-technical consumers out here and I'm certain it would be time well spent. How about a glossary of terms? What the heck is parallax? Retina ready and why should we care? Which kinds of templates require what kind of editing software? As is, the burden falls on every author to deal with all the dumb questions from we, the unskilled, who simply want to produce a stylish, functional website.
First off I (charlie4282) use the trademark Unified as my avatar so am the same person.
Second I did clearly answer the question 'You don’t need Dreamweaver only Notepad or one of the countless free HTML editors online. Open HTML files in those – edit the copy. Open image files in image editor change those and either save using the same file name or update the image path in the HTML to anew name and just drop ALL files in the template into your host root directory.'
For what its worth to answer your question 'But I can’t figure out what products templates will work in this software or not ANY 'site template' or "wordpress theme" (i.e. the PHP files and CSS) can be opened in Dreamweaver as it is an editing tool for these mark ups and code.
That said you need to understand code to modify it properly and if it is WordPress for example then you need to obviously use the platform to make it work unlike HTML where you can just edit and upload it directly.
For what its worth there are several experienced authors and other in this community who go out of the way to support and help people form beginners to authors who have been rejected etc.
That said there is a degree of expected knowledge when purchasing a file, and (not mean offensively) envato is not a hand holding tutorial site.
The fact is the idea of a 'glossary' or 'list of software' (which by the way is difficult because there are so many options and alternatives but for reference PHP, CSS, HTML, JS etc can ALL be opened in Dreamweaver, Notepad of any other text editor.) would not solve the problem - ( not aimed at anyone in particular) too much 'support' etc form envato would cloud expectations.
MOST beginners even if told what to do would still struggle and what they really want is someone to help them build the site - and this is too much to ask of envato, authors or anyone else. Hence the freelancer comment. Just like anything else in life if you do not know how to do it you hire help.
