+
+## Install requirement
+
+1 - Update and Install packages :
+
+```sh
+apt-get update -y -qq
+apt-get install lxc lxcfs lxc-templates qemu qemu-utils qemu-kvm virtinst bridge-utils virt-manager libvirt-daemon libvirt-daemon-system virt-viewer libvirt-clients libosinfo-bin websockify sqlite3 novnc
+apt-get install python3 python3-flask python3-flask-login python3-flask-sqlalchemy python3-requests python3-lxc python3-libvirt python3-psutil python3-werkzeug python3-websockify python3-novnc
+```
+
+2 - Configure Libvirst to start on boot
+
+```sh
+systemctl --quiet enable --now libvirtd
+systemctl --quiet  start libvirtd
+```
+
+3 - Create a bridge nework
+
+```sh
+cp ./bridged.xml /usr/share/libvirt/networks/
+virsh net-define bridged.xml
+virsh net-start bridged
+virsh net-autostart bridged
+```
+
+## Create Database for user
+
+```sh
+sqlite3 db.db
+
+CREATE TABLE user (id INTEGER PRIMARY KEY AUTOINCREMENT, username NVARCHAR(200) NULL, email NVARCHAR(200) NULL, password NVARCHAR(200) NULL;
+
+```
+
+## Create first user
+
+1 - Generate encrypted password :
+
+```sh
+python3
+import app
+app.encrypt('Password')
+
+```
+2 - Fill Database with user info :
+
+```sh
+sqlite3 db.db
+
+INSERT INTO user (id,username,email,password) VALUES (1,'<you_username>','<your_email>','<your_previous_encrypted_password');
+```
+
+## Configure Reverse Proxy to get access to Consoles
+
+```sh
+ProxyPass /websockify ws://<server_ip>:6080/websockify retry=3
+ProxyPassReverse /websockify ws://<server_ip>:6080/websockify retry=3
+
+ProxyPass /socket.io ws://<server_ip>:5008/socket.io retry=3
+ProxyPassReverse /socket.io ws://<server_ip>:5008/socket.io retry=3
+```
+
+## Run and use
+```sh
+python3 app
+
+and go to https://<server_ip>:5007 with your credentials (mail and normal password)
+
+```
+
+## Systemd
+
+You can manage hype using Systemd management:
+
+```sh
+[Unit]
+Description= Hype2 service
+After=multi-user.target
+[Service]
+Type=simple
+Restart=always
+ExecStart=/usr/bin/python3 <path_to_change>/app.py
+[Install]
+WantedBy=multi-user.target
+
+```
+
+put this file in /etc/systemd/system/ and you can then enable it for autostart on boot and/or start/stop the app.
+
+## Configuration
+
+You can also change some configuration in the file *configuration.py* such as flask port, storage location...use it at your own risk.
