A Meetup is being hosted at the Austin Office on September 24th, 2024. Those interested in attending or speaking should express their interest. In Coder, templates help maintain consistency across developers' workspaces. Updating an existing template can be done locally and then pushed to the Coder server using various methods such as the Coder CLI, CI/CD, or third-party actions like Update Coder Template from GitHub marketplace. These updates ensure that all users have access to the latest version of templates.
