+# Preparation for a hackfest or workshop
+
+## Prepare VMs for OSM and the workstation
+
+```bash
+export OS_CLOUD="..."
+source environment-slices.rc
+export FLAVOR_NAME=osm.sanity
+export INSTANCE_PREFIX="osm-slices-"
+./openstack-create-vms.sh 1 4
+export INSTANCE_PREFIX="slices-workstation-"
+./openstack-create-vms.sh 1 1
+openstack server list
+```
+
+## Create users and projects in Openstack
+
+```bash
+export OS_CLOUD="..."
+source environment-slices.rc
+# If you want to change the env variables:
+# export USERNAME_PREFIX="slices"
+# export PROJECT_PREFIX="slices"
+# export PASSWORD_PREFIX="slices"
+# export PASSWORD_SUFFIX="Feb24!"
+./openstack-create-users-projects.sh 1 40
+```
+
+## Install OSM
+
+Connect to all OSM VMs with `ssh ubuntu@<IP_ADDRESS>` and run:
+
+```bash
+wget https://osm-download.etsi.org/ftp/osm-15.0-fifteen/install_osm.sh
+chmod +x install_osm.sh
+./install_osm.sh -y 2>&1 | tee osm_install_log.txt
+```
+
+## Configure OSM
+
+### Set environment variables
+
+```bash
+export OS_CLOUD="..."
+source environment-slices.rc
+openstack server list |grep -i "${INSTANCE_PREFIX}"
+declare -A -x OSM_VMS
+export OSM_VMS
+OSM_VMS["osm-slices-1"]="172.21.248.69"
+OSM_VMS["osm-slices-2"]="172.21.249.74"
+OSM_VMS["osm-slices-3"]="172.21.248.242"
+OSM_VMS["osm-slices-4"]="172.21.249.60"
+echo ${!OSM_VMS[@]}
+```
+
+### Update admin user and store credentials for admin users in all OSM
+
+These commands need to be run from a machine where osmclient is present.
+
+```bash
+echo ${!OSM_VMS[@]}
+for c in "${!OSM_VMS[@]}"; do
+    # Change admin password
+    ./osm-update-admin-user.sh ${OSM_VMS[$c]}
+    # Create admin credentials
+    ./osm-create-admin-creds.sh ${c} ${OSM_VMS[$c]}
+done
+# Credentials are stored in osm-creds folder
+ls ./osm-creds
+```
+
+### Create users and projects in all OSM and store credentials for users
+
+For instance, if there are 4 OSM instances and we want 10 users and projects on each instance:
+
+```bash
+echo ${!OSM_VMS[@]}
+n_ini=1
+n_osm_projects=10
+for c in $(for x in ${!OSM_VMS[@]}; do echo $x; done | sort); do
+    echo "Creating ${n_osm_projects} users in OSM ${c} (${OSM_VMS[$c]}) starting from ${n_ini}"
+    source ./osm-creds/admin-${c}.rc
+    ./osm-create-users-projects.sh ${n_ini} ${n_osm_projects}
+    ./osm-create-creds.sh ${n_ini} ${n_osm_projects}
+    n_ini=$((n_ini + n_osm_projects))
+done
+```
+
+## Configure workstation
+
+Check that workstation is reachable:
+
+```bash
+export OS_CLOUD="..."
+source environment-slices.rc
+openstack server list | grep -i workstation
+ssh ubuntu@<IP_ADDRESS>
+logout
+```
+
+Copy files to workstation:
+
+```bash
+scp environment-slices.rc workstation* ubuntu@<IP_ADDRESS>:
+```
+
+Add keys from instructors:
+
+```bash
+ssh ubuntu@<IP_ADDRESS>
+ssh-import-id-gh gerardo-garcia
+```
+
+### Install SW
+
+```bash
+ssh ubuntu@<IP_ADDRESS>
+./workstation-install-helm-kubectl.sh
+./workstation-install-osmclient.sh
+```
+
+### Create users
+
+```bash
+ssh ubuntu@<IP_ADDRESS>
+source environment-slices.rc
+./workstation-create-users.sh 1 40
+# This step will also copy the authorized_keys from ubuntu user to all new users
+
+# If needed, you can delete the users
+# ./workstation-delete-users.sh 1 40
+```
+
+### Allow SSH authentication
+
+Update file `/etc/ssh/sshd_config`in the workstation to allow SSH access with user and password.
+
+```bash
+ssh ubuntu@<IP_ADDRESS>
+cat /etc/ssh/sshd_config | grep PasswordAuthentication
+sudo sed -i "s/^PasswordAuthentication no/PasswordAuthentication yes/" /etc/ssh/sshd_config
+cat /etc/ssh/sshd_config | grep PasswordAuthentication
+sudo systemctl restart ssh
+```
+
+### (REMOTE) copy kubeconfig, clouds.yaml and osm.rc files
+
+```bash
+source environment-slices.rc
+./workstation-copy-files-users.sh <IP_ADDRESS> 1 40
+```
+
+## Clean
+
+Clean Openstack projects:
+
+```bash
+export OS_CLOUD="..."
+source environment-slices.rc
+openstack user list
+./openstack-clean-projects.sh 1 40
+./openstack-delete-users-projects.sh 1 40
+```
+
+Delete OSM VMs and workstation:
+
+```bash
+export OS_CLOUD="..."
+source environment-slices.rc
+export INSTANCE_PREFIX="osm-slices-"
+./openstack-delete-vms.sh 1 4
+export INSTANCE_PREFIX="slices-workstation-"
+./openstack-delete-vms.sh 1 1
