 # Concept and installation
 OIBus Agent is a tool used to embed through HTTP some protocol specific queries. For now, [ODBC](./odbc) and
 [OPCHDA](./opchda) are supported.
 
 OIBus can request the agent through its South connectors [ODBC](../south-connectors/odbc) and [OPCHDA](../south-connectors/opc-hda).

+## Setup
+Unzip the archive, from which you will get three files:
+- OIBusAgent.exe: binary used to run the agent
+- install-agent.bat: script used to install the agent as a Windows service
+- uninstall-agent.bat: script used to uninstall the service
+
+### Installation
+By default, running `install-agent.bat` install the agent as a service with the name `OIBusAgent` and will listen to port `2224`:
+```
+install-agent.bat
+```
+
+But it is also possible to specify a name and a port through the command line:
+```
+install-agent.bat -n="My OIBus Agent" -p=2225
+```
+
+### Uninstalling
+If the agent has been set up with default values, running the uninstallation script is enough:
+```
+uninstall-agent.bat
+```
+
+If the agent has been installed with a specific name, you must specify its name:
+```
+uninstall-agent.bat -n="My OIBus Agent"
+```
+
+## Running the agent
+If you just want to run the agent without using the service manager, simply run the following command in a terminal:
+```
+OIBusAgent.exe
+```
 
-<Tabs>
-  <TabItem value="windows" label="Windows" default>
-    <WindowsInstallation/>
-  </TabItem>
-  <TabItem value="linux" label="Linux">
-    <LinuxInstallation/>
-  </TabItem>
-</Tabs>
+That will run the OIBus agent on its default HTTP port 2224. You can specify another port with:
+```
+OIBusAgent.exe -p 2225
+```
