I did the get started doc and found a few typos. Here are fixes for them.

Your sentence misses a word.

Thanks!

Can you have a look at the failing build? You have a very simple problem to fix before this can get merged.

LGTM and by the way, kudos on your commits, they are nice and clean :)

Regarding the subject of your PR, not sure the things you found qualify as typos…

This is not correct, we support Symfony 2.7, too.....

Any idea how to write docs for both versions?

[greg0ire]

I don't think we should bother about that, people that still use sf < 3 are on old projects, and are seasoned sf developers, they know what bin/console means, they can make the translation.

[OskarStark]

symfony itself uses app/console instead of bin/console in docs currently

[greg0ire]

Aren't they planning to move to bin/console ?

yes but we don not fully support symfony 3.0 -> SonataUserBundle

Maybe using the composer notation ? Like symfony-bin-dir/console, symfony-var-dir/cache at al.

// This is how you tell composer where your stuff is in composer.json
{
  "extra": {
    "symfony-app-dir": "app",
    "symfony-web-dir": "web",
    "symfony-var-dir": "var",
    "symfony-bin-dir": "bin",
    "symfony-tests-dir": "tests",
  }
}

You don't have to use 3.0 to be able to use the 3.0 directory structure, and I think will have to switch sometimes anyway

Maybe using the composer notation ?

Again, not sure it's worth the hassle. By using bin/console, you risk less newbies literally typing symfony-app-dir/console. Again, the only people that this is important for are newbies IMO, and there are probably more using 3.0 than older versions, don't you think?

Agree, using the most up-to-date defaults is certainly more than enough.
