We need to start somewhere, and what better place than an editor. After all, we can't produce anything if we don't have something that we can use to write it! Editing Less files is very easy—they are plain text files, which can be edited in almost any editor.
The downside is that there are dozens of editors available, either free or at a cost. However, there are some editors that have support for Less either included by default or available as an add-on package, which includes the following:
