error: could not compile `example_bot` due to previous error
PS C:\Users\Death\Desktop\Botnet\botnet>

You need to build the example bot for the wasm32-unknown-unknown target. Running cargo build inside the example_bot directory should automatically set the correct target, but apparently that does not work when running with --manifest-path. I've updated the readme with new instructions to fix this. Please try it and let me know if you can get it to compile now.

[Evgene-Kopylov]

rustup target add wasm32-unknown-unknown 
cd example_bot
cargo build

compiled.

next is

\botnet> cargo build

or

> cargo build --release --manifest-path=botnet/Cargo.toml

results in

[JMS55]

You need to compile the example bot in release, or change that include_bytes path to /debug/.

[Evgene-Kopylov]

RUST_LOG=botnet is how you set an environment variable for a command in linux. I'm not sure what the powershell equivalent would be, but you should be able to find the info on the internet.
