Install docs for both 3.3 and 4.0 provide elgg 4.0

Please compare:

  1.  http://learn.elgg.org/en/3.3/intro/install.html
  2. http://learn.elgg.org/en/4.0/intro/install.html

and note (line 2 below) that both have the user installing "dev-master"

composer self-update
composer create-project elgg/starter-project:dev-master ./path/to/project/root
cd ./path/to/project/root
composer install
composer install # 2nd call is currently required
vendor/bin/elgg-cli install # follow the questions to provide installation details

 

My intention was to install 3.3, but I wound up with 4.0.6 (dev-master) .. is it possible to downgrade or do I need to nuke everything and start again?
