Using Less as a CSS pre-processor in your project? No problemo, Font Awesome has a Less version if you'd prefer to import our styling into your workflow.
You'll find everything you need in the fontawesome6 directory of the alpha zip. Below is the list of files made specifically for Less. You can add them all to your project or pick just the ones you need.

Copy the less folder into your project. Then copy the entire webfonts folder into your project where your static files get served.
Open your project's less/variables.less and edit the @fa-font-path variable to point to where you placed the webfonts folder.
@fa-font-path: "../webfonts";
Import Font Awesome by adding @import "less/fontawesome.less" in your main Less file. Also, import one or more styles @import "less/solid.less" in your main Less file.
Compile your code and get to using those new icons in your project!
Make sure the font path and your webfonts directory are relative to where your compiled CSS will be located.
You can use .fa-icon; to get things set up as an icon. Use .fa-solid; to create an icon in the Solid style. Import other styles to use other prefixes. Use variables to include content values a little easier.
@import "./fontawesome/less/fontawesome";
@import "./fontawesome/less/solid";
@import "./fontawesome/less/brands";
.user {
  .fa-icon;
  .fa-solid;
  &:before {
    content: @fa-var-user;
  }
}
.twitter {
  .fa-icon;
  .fa-brands;
  &:before {
    content: @fa-var-twitter;
  }
}
| Utilities | What It Does | 
|---|---|
| .fa-content() | A mixin to make referencing icons via the CSS contentproperty a bit more easyAn icon's variable must be passed in (e.g. fa-content(@fa-var-user);). | 
| .fa-icon() | A mixin that contains all of the base style set up for an icon (minus an icon's style and specific name/unicode) compile | 
| .fa-size() | A mixin that calculates font size and vertical alignment for the relative sizing scale | 
| .fa-sr-only() | A mixin that visually hides an element containing a text-equivalent for an icon while keeping it accessible to assisitive technologies | 
| .fa-sr-only-focusable() | A mixin that is used alongside .fa-sr-only()to show the element again when it’s focused (e.g. by a keyboard-only user) |
