Redmine

Need to add section for 3.x install and upgrade to 3.x where change such text

Run the following command from your new Redmine root directory:

bundle exec rake generate_secret_token

This will generate a file (config/initializers/secret_token.rb) with a random secret used to secure session data.

to something like:
- follow official guide
- or just create secrets.yml file with such content:

production:
  secret_key_base:

- run rake secret and copy/paste output after secret_key_base:
Otherwise you'll get DEPRECATION WARNING: You didn't set config.secret_key_base in your production.log
