I worked as a software developer and recently I became the manager of some web development projects for clients. Can you please recommended some useful tutorials for web development project management through Jira Software?
Jira is simply a tool. You probably want to look at Scrum or Kanban for the actual process approaches.
The book "Kanban" by David Anderson is pretty much the go-to source for information on that.
For Scrum, the Scrum Guide is a great starting point.
