+**UNDER CONSTRUCTION!**
+
+In this lab, we will set up a simple topology with [containerlab](https://containerlab.dev/). We will create and modify gnmi-target-switch0 (server with a gNMI-target, handled as switch) that we manage with the goSDN controller.
+
+**Please note: You need to have the lab-vm or all the software in [Prerequisites](Labs/Prerequisites) installed to run this lab.**
+
+The figure below shows what we want to set up using the goSDN-Controller, goSDN-CLI and gNMI:
+![lab01-network](uploads/ee4893bcc17020b444ba0b11012ea3f5/lab01-network.png)
+
+## Run command to build the docker image for the gNMI target
+First, go to your local gnmi-target repository:
+
+```bash
+cd gnmi-target
+```
+Next, build the image:
+
+```bash
+git checkout develop
+make container
+```
+
+## Run the containerlab
+Go to the directory of gosdn and use following command:
+```bash
+make containerlab-slim-start
+```
+
+## Download the folder below and place it into the artifacts folder of your gosdn folder
+
+[lab01.zip](uploads/e7bbf3f0575a4e471c8ba8862c0b2dde/lab01.zip) or get it with wget if you are using Linux:
+
+```bash
+wget https://code.fbi.h-da.de/danet/gosdn/-/wikis/uploads/e7bbf3f0575a4e471c8ba8862c0b2dde/lab01.zip
+```
+
+## Open a new terminal and start the CLI to talk to the controller (Do not close the previous terminal)
+
+Build command prompt
+
+```bash
+make build
+cd artifacts
+./gosdnc prompt
+```
+
+![CLI_image](uploads/155116353627ae3070a53b3fdaeda421/CLI_image.PNG)
+
+## Login into the controller with the credentials
+
+```bash
+login --controller 172.100.0.5:55055 --u admin --p <password>
+```
+
+## To get the (password) go to the previous terminal and use the following commands
+
+```bash
+docker logs clab-gosdn_csbi_arista_base-gosdn
+```
+
+In the end of the script a 16 character alphanumeric password is generated like this: “Generated admin password: uyslboh15gjp9dne” (not the actual password, just an example)

+
+## Set-up the PND ID
+
+```bash
+pnd use (Choose ID from the displayed menu)
+```

+
+## Set-up the switches
+Switch0:
+```bash
+mne create --address 172.100.0.11:7030 --name switch0 --username admin --password admin --tls --plugin-id d1c269a2-6482-4010-b0d8-679dff73153b
+```
+Switch1:
+```bash
+mne create --address 172.100.0.12:7030 --name switch1 --username admin --password admin --tls --plugin-id d1c269a2-6482-4010-b0d8-679dff73153b
+```
+## Check if the switches were created
+
+```bash
+mne list
+```
+In here, the UUID is also visible which we need for the next step:![Lab00_mne_list](uploads/23ec897ac1b9a307e733786529cf875f/Lab00_mne_list.png)
+
+**Please note that the UUID may vary.**
+
+## Configuration of the switches(the UUID have to be changed according to the output from the devices)
+
+### Switch 1
+
+```bash

+
+### Switch 2

+```
+
+If you've cloned the goSDN repo from [here](https://code.fbi.h-da.de/danet/gosdn) and have all the requirements, then you can start the containerlab topology (which is defined below) using the command `make containerlab-start` from within the root of the repository
+
+## CLI and the controller
+
+### Setup centos devices
+
+Since we do not have access via gNMI on those devices, we have to perform some steps manually, within the container itself.
+
+First we have to get into the centos device via
+`docker exec -it clab-gosdn_csbi_arista_base-centos1 bash`
+and run the following commands:
+
+```text
+[root@centos1 /]# ip address add 10.0.0.100/24 dev eth1
+[root@centos1 /]# ip route del default
+[root@centos1 /]# ip route add default via 10.0.0.1 dev eth1
+[root@centos1 /]# exit
+```
+
+`docker exec -it clab-gosdn_csbi_arista_base-centos2 bash`
+
+```text
+[root@centos2 /]# ip address add 192.168.0.100/24 dev eth1                                                           
+[root@centos2 /]# ip route del default                                                                               
+[root@centos2 /]# ip route add default via 192.168.0.1 dev eth1                                                      
+[root@centos2 /]# exit
+```
+
+## Testing our setup
+
+### Ping the centos devices with their ip's
+
+```bash
+docker exec -ti clab-gosdn_csbi_arista_base-centos1 ping 192.168.0.1
+docker exec -ti clab-gosdn_csbi_arista_base-centos2 ping 10.0.0.1
+```
