+1. Install dependencies:
+   ```
+   sudo yum -y install python-virtualenv python-devel libvirt-devel glibc gcc nginx supervisor libxml2 libxml2-devel git
+   ```
+
+2. Create working directory and repo into it:
+   ```
+   sudo mkdir /srv && cd /srv
+   sudo git clone https://github.com/retspen/webvirtcloud && cd webvirtcloud
+   ```
+
+3. Edit 'conf/requirements.txt':
+   - change libvirt-python to version, installed in your system (yum info libvirt-python, for now it's 3.2.0);
+   - uncomment libxml2-python from retspen repo / comment gnome version.
+
+4. Install webvirtcloud:
+   ```
+   sudo virtualenv venv
+   sudo source venv/bin/activate
+   sudo venv/bin/pip install --upgrade pip
+   sudo venv/bin/pip install -r conf/requirements.txt
+   sudo cp conf/nginx/webvirtcloud.conf /etc/nginx/conf.d/
+   sudo venv/bin/python manage.py migrate
+   ```
+
+5. Edit '/etc/supervisord.conf':
+   Add the following after the [include] line (after **files = ... ** actually):
+   ```
+   [program:webvirtcloud]
+   command=/srv/webvirtcloud/venv/bin/gunicorn webvirtcloud.wsgi:application -c /srv/webvirtcloud/gunicorn.conf.py
+   directory=/srv/webvirtcloud
+   user=nginx`<br />
+   autostart=true`<br />
+   autorestart=true`<br />
+   redirect_stderr=true`<br />
+
+   [program:novncd]
+   command=/srv/webvirtcloud/venv/bin/python /srv/webvirtcloud/console/novncd
+   directory=/srv/webvirtcloud
+   user=nginx
+   autostart=true
+   autorestart=true
+   redirect_stderr=true
+   ```
+
+6. Edit the '/etc/nginx/nginx.conf':
+   Comment out 'server' section:
+   ```
+   #    server {
+   #        listen       80 default_server;
+   #        listen       [::]:80 default_server;
+   #        server_name  _;
+   #        root         /usr/share/nginx/html;
+   #
+   #        # Load configuration files for the default server block.
+   #        include /etc/nginx/default.d/*.conf;
+   #
+   #        location / {
+   #        }
+   #
+   #        error_page 404 /404.html;
+   #            location = /40x.html {
+   #        }
+   #
+   #        error_page 500 502 503 504 /50x.html;
+   #            location = /50x.html {
+   #        }
+   #    }
+   ```
+7. Change owner for working directory:
+   ```
+   sudo chown -R nginx:nginx /srv/webvirtcloud
+   ```
+
+8. Enable end start services:
+   ```
+   sudo systemctl enable nginx
+   sudo systemctl enable supervisord
+   sudo systemctl start nginx
+   sudo systemctl start supervisord
+
+9. SELinux.
+   You can disable / switch to permissive mode or check 'denied' messaget in '/var/log/audit/audit.log' and create custom selinux modules:
+   - check last message with 
+     ```
+     cat /var/log/audit/audit.log | grep denied | tail -1
+     ```
+   - create and install module:
+     ```
+     cat /var/log/audit/audit.log | grep denied | tail -1 | audit2allow -M <MODULE_NAME> && semodule -i <MODULE_NAME>.pp
+     ```
+
