+## Using `pmt-static` via ADB
+
+This guide will show you how to use the **static** version of Partition Manager Tool (`pmt-static`) on your Android device through **ADB**.  
+It’s written for beginners — no advanced knowledge needed.
+
+---
+
+## 📦 Why Static Version?
+The **static** build of PMT contains everything it needs inside one single file.  
+This means you can run it directly on your Android device **without** installing extra libraries.  
+Perfect for quick tasks via ADB.
+
+---
+
+## 📋 Requirements
+- **ADB installed** on your computer  
+  (Part of the Android SDK Platform Tools — [Download here](https://developer.android.com/studio/releases/platform-tools))
+- **USB Debugging enabled** on your phone  
+  (Settings → Developer options → Enable USB debugging)
+- Your **phone connected via USB** and recognized by ADB
+
+---
+
+## 🚀 Step-by-Step Usage
+
+### 1️⃣ Get the Correct Binary
+Download the **`pmt-static`** file that matches your device’s architecture:
+- **`pmt-static-arm64-v8a`** → For 64-bit devices
+- **`pmt-static-armeabi-v7a`** → For 32-bit devices
+
+Unzip the downloaded `.zip` file — you should now have a `pmt` binary.
+
+---
+
+### 2️⃣ Push the Binary to Your Device
+Use ADB to copy the `pmt` file to your phone’s temporary folder:
+```bash
+adb push pmt /data/local/tmp/pmt
+```
+
+### 3️⃣ Open an ADB Shell
+Access your device shell:
+```bash
+adb shell
+```
+
+### 4️⃣ Change to the Directory
+Move into the temporary directory where pmt is stored:
+```bash
+cd /data/local/tmp
+```
+
+### 5️⃣ Give Execute Permission
+Allow the binary to be executed:
+```bash
+chmod 755 pmt_static
+
+# Rename for more easily
+mv pmt_static pmt
+```
+
+### 6️⃣ Run PMT
+You can now run PMT directly from this directory:
+
+```bash
+./pmt --help
+```
+Example — Back up the boot partition:
+
+```bash
+./pmt backup boot
+```
+
+### 💡 Tips
+Commands must be run from /data/local/tmp unless you move pmt elsewhere.\
+The /data/local/tmp folder is cleared when you reboot your device.\
+Static builds are completely standalone — no missing library issues.
