+## ⭐ Getting started
+
+Import the `isDocker` function and use it:
+
 ```ts
 import { isDocker } from "https://deno.land/x/is_docker/mod.ts";
 
-const checkDocker = async () => {
-  if (await isDocker()) {
-  console.log('You are inside docker environment!');
-  } else {
-    console.log('You are not in docker environment!');
-  }
-}
+const inDockerContainer = await isDocker(); // boolean
+```
+
+### CLI with [DPX](https://github.com/denorg/dpx)
 
-checkDocker();
+After [installing DPX](https://github.com/denorg/dpx), you can directly use the CLI using the `dpx` command:
+
+```bash
+dpx is_docker --allow-read
+# You are not in a Docker environment
 ```
 
-Alternatively, you can use it directly from the CLI by using deno run:
+### CLI
+
+Alternatively, you can use it directly from the CLI by using `deno run`:
 
 ```bash
-deno run --allow-read https://deno.land/x/is_docker/cli.ts
+deno run --allow-read https://deno.land/x/is_docker/cli.ts <arguments>
 ```
 
 You can also install it globally using the following:
 
 ```bash
-deno install --allow-read -n is-docker https://deno.land/x/is_docker/cli.ts
+deno install --allow-read -n is_docker https://deno.land/x/is_docker/cli.ts
 ```
 
 Then, the package is available to run:
 
 ```bash
 is_docker
+# You are in a Docker environment
 ```
