• tester adds a Bug ticket to the Trello to the Bugs column
• I inspect a ticket description and if I need more details I will write about it in comments and will move it to Rejected
• Tester can answer/add details and get it back to Bugs
• if a Bug ticket is fine I will do it and after the completion I will move it to To Test column
• tester retests a ticket and if bug is gone he writes "working" comment and archives it
• if it is not working -- writes "not working" with details and moves back to the Bugs
• if tester founds that a new bug has been introduced but the original bug is fixed he still archives the bug ticket and opens another one on a new bug
