+
+### Windows
+Head over to the [Releases](https://github.com/cheat/cheat/releases/latest) page and download `cheat-windows-amd64.exe.zip`.
+
+1. **Extract the archive**:  
+   Extract the executable into your local appdata directory:
+   ```powershell
+   Expand-Archive .\cheat-windows-amd64.exe.zip -DestinationPath $env:LOCALAPPDATA\cheat
+   ```
+   **Note**: You can install `cheat` to any other location if preferred, simply substitute your chosen installation path in steps 2 and 3 below.
+
+2. **(Optional) Create a symbolic link**:  
+   To facilitate invoking `cheat` via `cheat.exe`, you can create a symbolic link:
+   ```powershell
+   saps -v runas cmd -args "/c mklink %LOCALAPPDATA%\cheat\cheat.exe %LOCALAPPDATA%\cheat\cheat-windows-amd64.exe"
+   ```
+
+3. **Add `cheat` to your PATH**:  
+   Check if `cheat` is already in your PATH, and if not, append it:
+   ```powershell
+   if (-not (("$env:PATH" -cmatch "\\cheat") -or "$(where.exe cheat.exe 2>$null)")) {
+     $NEWPATH = "$env:PATH;$env:LOCALAPPDATA\cheat";
+     write-host $NEWPATH;
+     saps -v runas cmd -args "setx /M PATH `"$NEWPATH`""
+   } else {
+     write-host 'Cheat is already found on your PATH, skipping...'
+   }
+   ```
+
+4. **Restart your PC or shell**:  
+   To apply the PATH changes, either restart your computer, or close and reopen any terminal/PowerShell sessions.
+
+5. **Install Verification**:  
+   In your __freshly opened__ `powershell` or `CMD` terminal, invoke `cheat`:
+   ```powershell
+   cheat
+   ```
+   If the install was successful, you should see the initial run dialog. This will present you with the option to generate a new config file and download community cheatsheets.
+
+  **Troubleshooting**
+
+  If `cheat` isn’t running after installation:
+
+- **Verify the PATH was applied correctly**:
+  Verify your `cheat` path is present in the system environment variables. If it’s missing, try step 3 again to add it to your PATH.
+
+- **Loosen ExecutionPolicy**:
+  If at any point you run into issues with PowerShell’s script execution policy, you can temporarily relax it:
+  ```powershell
+  Set-ExecutionPolicy -Scope Process -ExecutionPolicy RemoteSigned
+  ```
+  This will let you run scripts for the current shell session without making permanent changes to the system policy.
+
+- **Try another installation method**: If you're still having problems after trying the above, you can try installing `cheat` via `docker` or `go install`.
