A THREAD FOR NEWCOMERS!

Basically, everything is clear except how to choose a template, where they are located, and how to understand if this template is suitable for me, and how to decipher a template? For example, 2SM4d?

GoedenDag provided a specific address - you can find each template with a detailed description by following the links. Below the description, there are attachments (a text file of the template). There is also general information about concepts and conventions in templates. Study all of this, and you will be happy. As for whether it suits you or not, that's a matter of personal taste (like choosing a girlfriend).
