When I install drupal console, feel like there is some problems with the way is writing. The instructions only have a comment and the command, so feel like all steps are simple options and you dont need to follow steps. This is my sugestions to improve it:
Work Faster and Smarter.
Steps to follow:
1- Run this in your terminal to get the latest project version:
curl https://drupalconsole.com/installer -L -o drupal.phar
Or if you don't have curl:
php -r "readfile('https://drupalconsole.com/installer');" > drupal.phar
2- Accessing from anywhere on your system (in some systems need sudo):
mv drupal.phar /usr/local/bin/drupal
3- Apply executable permissions on the downloaded file:
chmod +x /usr/local/bin/drupal
4- Copy configuration files to user home directory:
drupal init --override
5- Check and validate system requirements
drupal check
the installation is finished!
Download, install and serve Drupal 8:
drupal chain --file=~/.console/chain/quick-start.yml
Create a new Drupal 8 project:
drupal site:new drupal8.dev
Lists all available commands:
drupal list
Update DrupalConsole to the latest version:
drupal self-update
Im not sure if installations process end in step 5 but if im correct after the last step. give a end message and begin with Options: terminal commands you can use atfer installation but not part of the process.

clear documentation is not a novice specific affair, it is a dev self ensurance in dev<>user communication to make sure that all steps are done like expected before hunting white rabbits by issue reports emerged from unclear use cases...
Instead of adding numbers why not just break in two groups
