+General Overview
+-
+
+The UC serves as the main logistic station for all the client/CEO applications which are used
+inside the corporation. This UC stores
+- credentials for the users and ceo;
+- registered departments, as well security levels and the encrypting/decrypting keys for the files;
+- backup schemes for each user, as well as the IP, as well as the IPs where each computer is located;
+
+The main endpoints of the application are:
+
+- Users:
+
+ - Can register/login in the system;
+ - Update the information (username, email, password);
+ - Change the working department (the client app will prompt the CEO password request to proceed);
+ - Retrieve the full list of departments for the sign-up / 'change department' procedure;
+ - Retrieve the full list of users and their IPs for sharing a file
+
+
+- CEO:
+
+ - Can log in the system;
+ - Can change the email (the password can only be retrieved by the admin);
+ - Delete users from the system;
+ - Create / Delete departments, as well as managing the security levels of each department;
+ - Retrieve the full list of users and their IPs for sharing a file
+
+
+- Admin:
+
+ - Reset the server to default state;
+ - Retrieve the CEO login information, as well as a list of all users in the system;
+
+
+- Backup Schemes:
+
+ - At a request, will get the ID of a user, their IP and the backup directory structure to place it in the scheme,
+ as well as the data size of the backup
+
+
+Other Features
+-
+The UC will also create a separate process which at a set interval of time will retrieve from the admin config, as
+well as from the CEO config, the ID so that it will be used to authenticate the users at their endpoints.

+General overview
+-
+
For the use of the admin console, start with 'npm run start' the UI frontend.
To see/modify the initial login credentials check the /config/config.json file.
-WITHOUT SETTING THE CONFIG FILE FOR THE SERVER (API KEY) THE SERVER WILL NOT START!
\ No newline at end of file
+WITHOUT SETTING THE CONFIG FILE, THE SERVER WILL NOT WORK AS INTENDED!
+(click on the 'Reset UC' when first configuring the server to bring the
+UC at the initial state)
+
+Because the client and CEO apps are dependent on the Central Unit (UC), we strongly
+suggest you to make backup at a regular interval in case of hardware failing you will
+only have to deploy the server with the configurations already existing.
+
+Important aspects:
+-
+
+- The starting/stopping of the UC is handled by this 'Admin Console'. The server will not
+work if the server which servers as the 'Admin Console' is not running.
+- The main server will run at the port 5000, so make sure to configure your routers to
+enable routing to the server;
+- The client and CEO backup system of their applications will need access at ports 5001 and 5002,
+so also make sure to open those ports as well;
+- If the CEO wants to change the email address linked to the account, his password will be changed
+to a low-risk password, so make sure after any release to specify the account information;
+
+Closing thoughts
+-
+
+We really hope that you will enjoy our application and for any issues, feel free to contact us at
+'username@ourdomain.com' for troubleshooting and other problems.
