+Then you can specify custom Chromium location as following.
+```javascript
+const test = require("node:test");
+const puppeteer = require("puppeteer-core");
+const chromium = require("@sparticuz/chromium");
+
+test("Check the page title of example.com", async (t) => {

+    executablePath: await chromium.executablePath('/opt/chromium'),

+
+  const page = await browser.newPage();
+  await page.goto("https://example.com");
+  const pageTitle = await page.title();
+  await browser.close();
+
+  assert.strictEqual(pageTitle, "Example Domain");
+});
+```

 Alternatively, you can also download the layer artifact from one of our [CI workflow runs](https://github.com/Sparticuz/chromium/actions/workflows/aws.yml?query=is%3Asuccess+branch%3Amaster). Use the `chromium.zip` INSIDE the artifact as the layer. Also, the artifact will expire from Github after a certain time period.
