description: Drive the CodeKit app from the command line — compile files, build, preview in a browser, change project settings, set a project up. Use whenever CodeKit is mentioned, a folder is described as a CodeKit project, or a CodeKit project is to be created, compiled, built or previewed.

# CodeKit

CodeKit is a macOS app that compiles and optimises the assets of a web project — Sass, Less, Stylus,
Javascript, Typescript, CoffeeScript, Kit, Pug, Haml, Markdown, images — and serves the result to a browser
that reloads itself. A folder CodeKit has open is a "CodeKit project".

It can be driven from the command line. Use that whenever the person mentions CodeKit, says a folder is a
CodeKit project, or asks for one to be set up, compiled, built or previewed.

```
codekit --help
```

If `codekit` is not on the PATH, it is here:

```
~/Library/Application Support/com.incident57.CodeKit3/bin/codekit
```

**Read `--help` before doing anything else.** It is the whole interface — every command, every option, the
exit codes, and the handful of rules that will otherwise have you reporting success while getting a wrong
result. Do not guess at commands.
