Add the following to your `deps.edn`:

```clj
:aliases {:check {:extra-deps {athos/clj-check {:git/url "https://github.com/athos/clj-check.git"
:sha "0ca84df1357d71429243b99908303f45a934654c"}}
:main-opts ["-m" "clj-check.check"]}}
:aliases
{:check
{:extra-deps
{com.github.athos/clj-check
{:git/url "https://github.com/athos/clj-check.git"
:sha "9e9282a6455f58a2015d267ad503b812ec6cdeb3"}}
:exec-fn clj-check.check/check}
```

If your project has its codebase under some directories other than `src` (say `src/clj` and `src/cljc`), specify them as the command line arguments as follows:

```clj
:aliases {:check {...
:main-opts ["-m" "clj-check.check" "src/clj" "src/cljc"]}}
:aliases
{:check
{...
:exec-args
{:source-paths ["src/clj" "src/cljc"]}}}
```


Then, run `clj-check` via the declared alias:

For clj versions 1.10.1.697 and greater:

```
clj -M:check
clj -X:check
```

For older versions:
OR

Run `clj-check` with CLI overrides
```
clj -A:check
clj -X:check :source-paths "[\"src/clj\"]"
```

Can get rid of this when we switch over to -X and remove support for -M
