Document User Journey

[No9]

As per the general drive to document user journeys in node tooling this issue is to track the creation of an llnode tutorial as part of
nodejs/diagnostics#502

The next step would be to review content that is already available and map out a tutorial structure
This post may be a reasonable starting point.

I'll pick that one ^^ 👋

Update: I didn't start it at the moment.

I'm trying to finish and release this one: nodejs/diagnostics#572

Then I'll jump on it ^^

No worries - I forgot to mention these videos of @watson and @joyeecheung may bring some inspiration too

Hi there 👋

For the delivery of this task, I propose:

1. I'll submit a plan for this user journey documentation.
2. We'll discuss the shape of the content together
3. I'll write down the full article

WDYT?

Hey people 👋

Sorry for the wait. We finished the structure of the post, now I'm trying to play with lldb (then with core dumps) on my machine. But I got very different results from what I saw in previous lectures (IBM or Colin's one). Maybe it's because I'm on M1; I open an issue on SOF. Anyway, I'll borrow the intel mac of my wife too if it fixes the issue.

I'll keep you informed, but the delivery will take longer than I expected.

Update: I tried on an Intel machine, and it seems to work pretty fine 🎉

I'll continue my experiment with my wife's laptop 😅 (and will probably raise an issue on apple's side).

@tony-go was you're wife's laptop preconfigured? I was wondering how valid this PR is
#373

@No9 on my wife's laptop xcode was installed (then with lldb within).

I install llnode with brew and it works fine ^^

I'll be able to continue my exploring phase :) (and will raise an issue to Apple for M1 issue)
