+# Upscalers - upscayl-bin Windows 11 — Command-Line Installation Guide
+
+There are two pieces you need: the **binary** (the `upscayl-bin` executable) and the **model** (upscayl models).
+
+---
+
+## Step 1 — Download the Binary
+
+The upscayl-bin binary can be downloaded from the official upscayl repository or from the releases page.
+
+1. Go to: [https://github.com/TNTwise/Universal-NCNN-Upscaler/releases](https://github.com/TNTwise/Universal-NCNN-Upscaler/releases)
+2. Download the latest Windows zip, e.g. `upscayl-bin-YYYYMMDD-windows.zip`
+3. Extract it to a folder, e.g. `C:\tools\upscayl-bin\`
+
+The package includes all binaries required — it is portable, so no CUDA or PyTorch runtime environment is needed.
+
+---
+
+## Step 2 — Add to PATH
+
+To run `upscayl-bin.exe` from any directory (instead of always `cd`-ing into the install folder), add the extraction folder to your system **PATH**:
+
+```text
+C:\tools\upscayl-bin\
+```
+
+Then open a new terminal and verify:
+
+```powershell
+upscayl-bin -h
+```
+
+## Step 3 — Download Models
+
+The models can be downloaded from the links found in the `README.md` file of the upscayl-bin directory.
+
+The default model used by the scripts is the `4xNomos8kSC` model.
+
+1. Go to: [https://github.com/TNTwise/Upscaling-Models-NCNN/releases/tag/Realistic](https://github.com/TNTwise/Upscaling-Models-NCNN/releases/tag/Realistic)
+2. Download the `4xNomo8kSC.zip` file
+3. Extract the 2 files (`4xNomos8kSC.bin` and `4xNomos8kSC.param`) directly to the root of the **models** directory (create it if it doesn't exist) in `upscayl-bin`, e.g. `C:\tools\upscayl-bin\models\`
+
+You can also download other models if you want to use them instead of the default `4xNomos8kSC` model. They should be extracted to the same `models` directory.
+
+---
+
+## Step 4 - Set UPSCAYL_HOME
+
+The scripts that use upscayl-bin (for example `Clone-Image.ps1 -Upscale`) read the environment variable **UPSCAYL_HOME**. Set it to the same folder that is on PATH. The models are read from `%UPSCAYL_HOME%\models`:
+
+```text
+UPSCAYL_HOME=C:\tools\upscayl-bin\
+```
+
+Set the variable as a persistent user or system environment variable, then open a new terminal. The scripts also need `NCNN_GPU_ID`; see [NCNN_GPU_ID](index.md#ncnn_gpu_id).
