+## Images installation
+
+### Arista cEOS
+
+To download and install the arista cEOS image, you need to be registered to [arista.com](https://www.arista.com/en/support/software-download).  
+Once you created an account, please logged in and down the cEOS docker images.  
+
+To add this new image to docker, please use the docker CLI command :
+```bash
+docker import cEOS-lab-4.30.3M.tar ceos:4.30.3M
+```
+
+### Cisco N9Kv
+
+Cisco’s N9Kv is also available for free (again, locked behind an account registration).  
+Please, download the qcow2 image and move it to the vrnetlab/n9kv folder :
+
+```bash
+➜  n9kv git:(master) pwd
+/opt/vrnetlab/n9kv
+➜  n9kv git:(master) ls -l
+total 1931856
+drwxr-xr-x 2 root root       4096  8 oct.  13:44 docker
+-rw-r--r-- 1 root root        508  8 oct.  13:44 Makefile
+-rwxr--r-- 1 root root 1978204160 14 mai    2022 nxosv.10.2.3.qcow2
+-rw-r--r-- 1 root root        585  8 oct.  13:44 README.md
+```
+
+Be sure to use the "n9kv" folder and not the "nxos" folder - the "nxos" folder is for the older titanium images. Once the image is copied here, trigger "make" to build the docker image for this
+
+```bash
+➜  n9kv git:(master) sudo make                                
+for IMAGE in nxosv.10.2.3.qcow2; do \
+        echo "Making $IMAGE"; \
+        make IMAGE=$IMAGE docker-build; \
+done
+Making nxosv.10.2.3.qcow2
+make[1] : on entre dans le répertoire « /opt/vrnetlab/n9kv »
+rm -f docker/*.qcow2* docker/*.tgz* docker/*.vmdk* docker/*.iso

+make IMAGE=$IMAGE docker-build-image-copy
+make[2] : on entre dans le répertoire « /opt/vrnetlab/n9kv »
+cp nxosv.10.2.3.qcow2* docker/
+make[2] : on quitte le répertoire « /opt/vrnetlab/n9kv »
+(cd docker; docker build --build-arg http_proxy= --build-arg https_proxy= --build-arg IMAGE=nxosv.10.2.3.qcow2 -t vrnetlab/vr-n9kv:10.2.3 .)

+make[1] : on quitte le répertoire « /opt/vrnetlab/n9kv »

+
+Now you should see images available to use :
+```bash
+➜  n9kv git:(master) sudo docker images 
+REPOSITORY         TAG       IMAGE ID       CREATED         SIZE
