1. It is advisable to create and activate a virtualenv before starting the project. However it is not a requirement to run the project.
2. The application can be started by running a single bash script run.sh inside src folder.
3. Make sure that you current directory is src and then run bash run.sh host_name <number_of_peers>
4. Hostname is a mandatory parameter and needs to be passed as a command line argument for the program to start.
5. Number of peers is optional paramter if passed the network will generate a network with equivalent number of peers otherwise it will default to six peer network based on the default config provided in config_file.
6. A sample run command might look like bash run.sh localhost 10 or bash run.sh localhost
7. In first case a 10 peer network will be created whereas in the second a network of 6 peers will be created.
8. The output of the program after running the network for a few minutes is present in src/tmp/output/output.txt

We have used matplotlib to show a graphical representation of the network. Plotting of graph might not work iff a GUI backend is not present. This issue can be resolved in two ways.

1. pass show_bazar argument as false when calling create_bazar function from main. This will prevent graph_generator to be invoked and hence resolving the error. However in this way the graphical representation of the network won't pe drawn.
2. Another way is to install a GUI-backend for matplotlib python sudo apt-get install python3-tk
