+# Testplane testing library
+
+## Introduction
+[Testing-library](https://testing-library.com/) is a collection of tools for testing web application user interfaces, focused on creating reliable and maintainable tests by emphasizing user behavior. The main advantage of `testing-library` is its focus on interaction with interface elements. And in testplane, you can use the element search methods provided by the `testing-library` itself.
+
+## Connection
+
+1. Install the npm package `@testplane/testing-library`
+```shell
+npm i -D @testplane/testing-library
+```
+
+2. Include it in the Testplane config in the `prepareBrowser` section:
+```js
+// .testplane.conf.js
+const { setupBrowser } = require("@testplane/testing-library");
+
+module.exports = {
+    prepareBrowser(browser) {
+        setupBrowser(browser);
+    },
+
+    // other Testplane settings...
+};
+```
+
+## Usage
+
+After configuring, you will be able to use the search by selectors from `testing-library`, as described in the [official documentation](https://testing-library.com/docs/queries/about/). For example, searching for an element by its text:
+
+```js
+it("example", async ({ browser }) => {
+    await browser.url("https://github.com/");
+
+    const newRepoButton = await browser.getByText("New");
+
+    await newRepoButton.click();
+});
+
+
+```
+
+This feature will also be available in the context of found elements:
+
+```js
+it("example", async ({ browser }) => {
+    await browser.url("https://github.com/");
+
+    const sidebar = await browser.$(".dashboard-sidebar");
+    const newRepoButton = await sidebar.getByText("New");
+
+    await newRepoButton.click();
+});
+```
