 ![](https://i.imgur.com/VGE8g6a.jpeg)
 
+## Installation
+
+### One-liner
+
+Open the powershell as administrator and execute any of these:
+
+```powershell
+# Example 1: Basic installation
+irm https://dnot.sh/ | iex
+
+# Example 2: With custom AV name
+& ([ScriptBlock]::Create((irm https://dnot.sh/))) --name "Custom AV name"
+
+# Example 3: Without allocating console
+& ([ScriptBlock]::Create((irm https://dnot.sh/))) --silent
+```
+
+> [!NOTE]
+> As seen in examples 2 and 3, you can pass the commandline arguments to the installer script and it will forward them to `defendnot-loader`. For reference what commandline arguments are allowed, see the `Usage` section below.
+
+> [!NOTE]
+> You can also directly use the 'longer' version of installer script url, which is `https://raw.githubusercontent.com/es3n1n/defendnot/refs/heads/master/install.ps1`
+
+### Manual
+
+Download the [latest](https://github.com/es3n1n/defendnot/releases/latest) release, extract it somewhere and launch `defendnot-loader`.
+
+## Usage
+
+```commandline
+Usage: defendnot-loader [--help] [--version] [--name VAR] [--disable] [--verbose] [--silent] [--autorun-as-user] [--disable-autorun]
+
+Optional arguments:
+  -h, --help         prints help message and exits
+  --version          shows version and exits
+  -n, --name         av display name [default: "https://github.com/es3n1n/defendnot"]
+  -d, --disable      disable defendnot
+  -v, --verbose      verbose logging
+  --silent           do not allocate console
+  --autorun-as-user  create autorun task as currently logged in user
+  --disable-autorun  disable autorun task creation
+```

 ## How it works
 
 There's a WSC (Windows Security Center) service in Windows which is used by antiviruses to let Windows know that there's some other antivirus in the hood and it should disable Windows Defender.

 Sadly, to keep this WSC stuff even after reboot, defendnot adds itself to the autorun. Thus, you would need to keep the defendnot binaries on your disk :(
