There are steps to get the software programm started:

For IPC:

To start IPC you need to install libcjson-dev by using command:
```
 $sudo apt-get install libcjson-dev
```

Then compile file server.c with command:

 $gcc -o server server.c -pthread -libcjson

Create .env file in Backend directory:

 DATABASE_URL=mysql://username:password@host/dbname
 ADMIN_PASSWORD=password

And run the file call_controller.py:

 python3 call_controller.py <ip address> <port number>

To start Frontend you need to install npm by entering following command:
```
 $sudo apt install npm
 $sudo npm install -g n
 $sudo n latest
```
You need to instal libfuse2 and fuse libraries:
```
 $sudo apt-get install fuse libfuse2
```
You need to run command to install node modules by entering following command in side Frontend directory:
```
 $npm install 
```
As well you have to define the IP address and port number in .env file by using the following:
```
 IP_IPC=<ip address of ipc>
 PORT_IPC=<port number>
```
Sometimes it is needed to change owner of the directory, it would be easy to change ownership of all subdirectories recursively:
```
 sudo chown -R user:group Frontend
```
If you want to start application you have to run following command in Frontend directory:
```
 $npm start
```
To build application for frontend you should run following command, your builded app will be in Frontend/release/build directory with the name 'ElectronReact-X.X.X.AppImage':
```
 $npm run package
```
And add the same .env file into the build directory before starting it
And run the 'ElectronReact-X.X.X.AppImage' file in terminal:
```
 ./ElectronReact-X.X.X.AppImage
```
