Installation notes

Install redmine_messenger_so plugin for Redmine

cd $REDMINE_ROOT
git clone https://github.com/smartorigin/redmine_messenger_so.git plugins/redmine_messenger_so
bundle config set --local without 'development test'
bundle install
bundle exec rake redmine:plugins:migrate RAILS_ENV=production

Make sure that the directory is named `redmine_messenger_so` (you cannot use another name for it)!
Restart Redmine (application server) and you should see the plugin show up in the Plugins page.
Under the configuration options, set the Messenger API URL to the URL for an
Incoming WebHook integration in your Messenger account and also set the Messenger
Channel to the channel's handle (be careful, this is not the channel's display name
visible to users, you can find each channel's handle by navigating inside the channel
and clicking the down-arrow and selecting view info).
