Include information of default dialect and dialect configuration

[concur1]

Added information on the dialect and dialect configuration to the readme.

You also need to update the README.MD file located at editors/code.

cp README.md editors/code/README.md

For the update

I think we should inform users that they need to use 'sqruff' as the config name and for the config key names.

I think we should inform users that they need to use 'sqruff' as the config name and for the config key names.

So change:

[sqlfluff]
dialect = SQLite

to

[sqruff]
dialect = SQLite

?

[gvozdvmozgu]

Yes, and also the file name. We have case-sensitive matching for the dialect name, so SQLite won't work. It should be sqlite.

[concur1]

Is Sqruff compatible with all Sqlfluff config files? Should I add a note around being able to copy over a config file from Sqlfluff?

[gvozdvmozgu]

We strive for backward compatibility with SQLFluff; some things might not work, but overall, yes.
