# Installing XDS client tools
[xds-agent](https://gerrit.automotivelinux.org/gerrit/gitweb?p=src/xds/xds-agent.git) is a client tool that must run
on your machine (user / developer host) to be able to use XDS.
You should establish the following chain:
- XDS Client: (`xds-cli` or XDS Dashboard).
- XDS Agent: (`xds-agent`) running on your machine.
- XDS Server (`xds-server`) running on a remote server and/or in a container.
Exchanges between these 3 tools are done though HTTP and Websocket protocols.
Default url/port mentioned in schema below can be change using config files.

Installation of other XDS client tools, such as `xds-cli` or `xds-gdb` is
optional and depends of what you want to do:
- [xds-cli](https://gerrit.automotivelinux.org/gerrit/gitweb?p=src/xds/xds-cli.git) : command line tool to used to interact with XDS (also used by IDE integration).
- [xds-gdb](https://gerrit.automotivelinux.org/gerrit/gitweb?p=src/xds/xds-gdb.git) : requested for debugging application.

1. Add binary to PATH:
- MacOs: create the .bash_profile `nano .bash_profile` and add `export PATH="/opt/AGL/xds/xds-agent:$PATH`
- Windows: change the system path via control panel or system settings or
`setx path "C:\AGK\xds\xds-agent;%path%"`
- repeat the previous steps to install other tools depending of your needs:
- `xds-cli` : requested for command line and IDE integration. ([released tarball link](https://github.com/iotbzh/xds-cli/releases)).
- `xds-gdb` : requested for debugging application. ([released tarball link](https://github.com/iotbzh/xds-gdb/releases)).
## Start xds-agent
XDS-agent is a client tool that must run on your local / user development
machine when you use XDS.
For **Linux** distro, a user systemd service is provided, `xds-agent.service`.
To start it automatically at boot and you can enable it using following commands:
```bash
# Enable xds-agent service at boot
systemctl --user enable xds-agent.service
```
To start the XDS-agent service:
```bash
# Manually start xds-agent service
systemctl --user start xds-agent.service
# Get status and log of xds-agent service
systemctl --user status xds-agent.service
```
On **MacOS** (or Linux), you can start-it manually using following commands:
```batch
/opt/AGL/bin/xds-agent
```
On **Windows**, you can start-it manually using following commands:
```batch
C:\AGL\xds\xds-agent\xds-agent.exe
