:four_leaf_clover: `Proposal`: `QuickStart` Optimization Discussion

[iyear]

What Would You Like to Add? Why Is This Needed?

After the discussion in #795, we ended up supporting two ways of exporting templates, curl /examples and dtm show config -t, which has important implications for the rewriting of the quickstart docs. We have the following options:

1. show only the curl xxx/eamples/ usage
2. show only the dtm show -t config usage, writing the existence of the examples dir as tips
3. show both. (but increases the complexity of the docs)

I prefer 2, which avoids as much as possible the download failure due to network reasons.

I prefer 2 too.
