+# DNS Performance Test Script
+
+This PowerShell script measures DNS query response times for a list of domains and outputs the results into a CSV file along with basic statistics.
+
+## 📋 Table of Contents
+
+* [Parameters](#-parameters)
+* [Installation](#-installation)
+* [Output](#-output)
+* [Statistics](#-statistics)
+* [Example](#-example)
+* [License](#-license)
+* [Author](#-author)
+
+---
+
+## ✅ Requirements
+
+* PowerShell 5.1 or higher
+* Read access to a text file containing the list of domains (default: `Domains.txt`)
+
+---
+
+## ⚙️ Parameters
+
+| Parameter           | Type     | Default       | Description                        |
+| ------------------- | -------- | ------------- | ---------------------------------- |
+| `$DnsServer`        | `string` | `1.1.1.1`     | DNS server to query                |
+| `$QueriesPerDomain` | `int`    | `3`           | Number of queries per domain       |
+| `$DomainsFile`      | `string` | `Domains.txt` | Path to the text file with domains |
+| `$ResultsFile`      | `string` | `Results.csv` | Path for the output CSV file       |
+
+---
+
+## 📥 Installation
+
+1. Download or copy the script into a `.ps1` file.
+2. Adjust the parameters (especially file paths) if necessary.
+3. Create a `Domains.txt` file in the script directory and list the domains you want to test.
+
+---
+
+## ▶️ Usage
+
+```powershell
+.\v1
+```
+
+---
+
+## 📄 Output
+
+* **CSV file** (`$ResultsFile`) with columns:
+
+    * `domain` — the queried domain name
+    * `query` — the iteration number of the query
+    * `response_ms` — response time in milliseconds, or `ERR` if the query failed
+* **Console output** showing each query result and final statistics.
+
+---
+
+## 📊 Statistics
+
+At the end of the script run, it prints:
+
+* **Average**: average response time (ms)
+* **Shortest**: fastest response time (ms)
+* **Longest**: slowest response time (ms)
+
+---
+
+## 📑 Example
+
+```powershell
+# Content of Domains.txt:
+example.com
+microsoft.com
+
+# Execute the script
+.\v1.ps1
+
+# Sample console output:
+[example.com] Query 1: 23.45 ms
+[example.com] Query 2: 22.87 ms
+[example.com] Query 3: 24.12 ms
+...
+==== Stats ====
+Average: 23.48 ms
+Shortest: 22.87 ms
+Longest: 24.12 ms
+```
