-# Install Beszel Agent As Service Under Windows
+# BeszelWin
 
-The Windows *cmd* file `install-beszel-service.cmd` installs the [Beszel](https://beszel.dev) agent as a service under Microsoft Windows.
+Build and install the [Beszel](https://beszel.dev) agent under Microsoft Windows.
 
-## Prerequisites
+## (1) Building the executable
 
-- Microsoft Windows 10 or later (32 or 64 bit)
-- Git installed
+### Prerequisites
 
-If you don´t have Git installed, either
+- Microsoft Windows 10 or later **Client** OS (64 bit)
 
-- install Git with Winget: `winget install git.git` or
-- download and extract the ZIP file from [Releases](https://gitea.elpatron.me/elpatron/Install-Beszel-Agent/releases/).
+*Building under Windows Server OS should be working, but you have to install Go and Git manually as Winget is not available for Windows server operating systems.*
 
-## Usage
+### Compiling
+
+Download and extract [install-beszel-service.zip](https://gitea.elpatron.me/elpatron/Install-Beszel-Agent/releases/download/1.0/install-beszel-service.zip).
+
+Open a `cmd.exe` shell and start the build-script:
+
+```
+.\build_agent.cmd
+```
+
+The script will install *Git* and *Go* (if not yet installed) with *Winget*, clone the *Beszel* repository and build a Windows 64 bit `agent.exe` binary.
+
+## (2) Installing the service
+
+### Prerequisites
+
+- Microsoft Windows 10 or later (32 or 64 bit) - *Server OS should work, too*
+
+### Installation
+
+Download and extract [install-beszel-service.zip](https://gitea.elpatron.me/elpatron/Install-Beszel-Agent/releases/download/1.0/install-beszel-service.zip) if you haven´t done this in *(1) Building the executable*.
 
 Open a `cmd.exe` shell with **administrative rights** .
 
+If you have built the agent by yourself: Copy your `agent.exe` binary to the directory where you extracted the scripts. Overwrite `agent.exe` from the archive.
+
+Example:
+
+```
+copy /y .\beszel\beszel\cmd\agent\agent.exe .
+```
+
+Start the installation script provided with your Beszel Ssh key:
+
 ````
-git clone https://gitea.elpatron.me/elpatron/Install-Beszel-Agent
-cd Install-Beszel-Agent
 .\install-beszel-service.cmd <your Beszel ssh key>
 ````
 
-## Explanation
-
 The script copies `agent.exe` into the directory `%ProgramFiles%\BeszelAgent` and takes usage of *[NSSM - the Non-Sucking Service Manager](https://nssm.cc/)* to install the service. If *NSSM* is not yet installed on your system, it will be downloaded and installed to the Beszel agent directory.
 
-The provided `agent.exe` was compiled on January, 17th 2025 by me and should be exchanged by a self compiled or official executable.
