-### Get the container
-
-Load the pre-build AGL SDK docker image including `xds-server`:
-
-```bash
-wget -O - http://iot.bzh/download/public/XDS/docker/docker_agl_worker-xds-latest.tar.xz | docker load
-```
-
-### List container
-
-You should get `docker.automotivelinux.org/agl/worker-xds:X.Y` image
-
-```bash
-# List image that we just built
-docker images | grep worker-xds

### Start xds-server within the container
-Use provided script to create a new docker image and start a new container:
-
-```bash
-# Get script

-#### Manually setup docker user id
-
-<!-- note -->
-**Note:**
-
-If you used `xds-docker-create-container.sh` script to create XDS
-docker container, user uid/gid inside docker has already been changed by this script.
-<!-- endnote -->
-
-If you plan to use **path-mapping sharing type for your projects**, you need to
-have the same user id and group id inside and outside docker.
-
-By default user and group name inside docker is set `devel` (id `1664`).
-
-Use following commands to replace id `1664` with your user/group id:
-
-```bash
-# Set docker container name to use (usually agl-xds-xxx where xxx is USERNAME@MACHINENAME-IDX-NAME)
-export CONTAINER_NAME=agl-xds-seb@laptop-0-seb
-docker ps | grep ${CONTAINER_NAME} || echo "ERROR: No container name \"${CONTAINER_NAME}\" please set a valid CONTAINER_NAME before you continue"
-
-# First kill all processes of devel user (including running xds-server)
-docker exec ${CONTAINER_NAME} bash -c "/bin/loginctl kill-user devel"
-
-# Change user and group id inside docker to match your ids
-docker exec ${CONTAINER_NAME} bash -c "usermod -u $(id -u) devel"
-docker exec ${CONTAINER_NAME} bash -c "groupmod -g $(id -g) devel"
-
-# Update some files ownership
-docker exec ${CONTAINER_NAME} bash -c "chown -R devel:devel /home/devel /tmp/xds*"
-
-# Restart devel autologin service
-docker exec ${CONTAINER_NAME} bash -c "systemctl start autologin"
-
-# Restart xds-server as a service (ssh port 2222 may depend on your container ID)
-ssh -p 2222 devel@localhost -- "systemctl --user start xds-server"
-```
-
-## Check if xds-server is running (open XDS webapp)
-
-**`xds-server` is automatically started** as a service on container startup.
-
-If the container is running on your localhost, you can access to a basic web
-application:
-
-```bash
-xdg-open http://localhost:8000
-```
-
-If needed you can status / stop / start it manually using following commands:
-
-```bash
-# Status XDS server:
-ssh -p 2222 devel@localhost systemctl --user status xds-server.service
-
-# Stop XDS server
-ssh -p 2222 devel@localhost systemctl --user stop xds-server.service
-
-# Start XDS server
-ssh -p 2222 devel@localhost systemctl --user start xds-server.service
-
-# Get XDS server logs
-ssh -p 2222 devel@localhost journalctl --user --unit=xds-server.service --output=cat
