We'll create a new cargo directory and add DarkFi to our Cargo.toml,
like so:
{{#include ../../../../../example/dchat/dchatd/Cargo.toml:darkfi}}
Be sure to replace the path to DarkFi with the correct path for your setup.
Once that's done we can access DarkFi's net methods inside of dchat. We'll need a few more external libraries too, so add these dependencies:
{{#include ../../../../../example/dchat/dchatd/Cargo.toml:dependencies}}
