Feedback - Getting started - Hello world

• Where to add dependencies
  It's a tiny feedback but I think it would be nice to add in which file to add the dependencies:
  Something like:

Next, add the necessary dependencies in Cargo.toml:

[dependencies]
tokio = "0.1"

• Add a section at the end to run the example:

1. Start a tcp server: nc -p 6142
2. Run: cargo run
3. What to expect

About to create the stream and write to it...
created stream
wrote to stream; success=true
Stream has been created and written to.

Looks good to me!

cc @rylev I think this would be applied to your section.

Running the following command per current docs gives me Connection refused error
nc -l 6142
I needed to run the following for the example to succeed
nc -l -p 6142

I would be happy to update once someone confirms that current docs are innacurate

PR in for requested change above: tokio-rs/website#283

[mziter]

Closed PR. Looks like my issue was with the version of netcat I was using. What are people's thoughts on adding an info or warning section about possible version issues. I originally discovered this because I got an error about the connection being refused, which might put off users.

[carllerche]

Right, we probably should move away from using netcat here given how there are differences across platforms.

Does anyone have ideas on an alternative?
