backdrop-drush-extension | A set of commands and boot class for Drush and Backdrop CMS

This project requires that you use the "8.x" branch of drush (https://github.com/drush-ops/drush/tree/8.x). Neither older versions of drush nor the new 9.x or master branches will work with this extension. There are a number of ways to install the Backdrop drush extension. All of them require the drush 8.x upstream. The main two ways are to install globally or site local installs. The main advantage to the global install is you install the Backdrop Drush Extension once it operates on all your Backdrop sites. The disadvantage is that it can effect how drush operates on Drupal sites (sometimes breaking some commands). We try our best to prevent that, but it has been known to happen. The main advantage to site local installs is that you will not break your Drupal sites or other Backdrop sites. The main disadvantage is you need to isntall drush proper and backdrop drush once per site.
I primarily use [Lando](https://docs.devwithlando.io) to do my development and Lando comes with the Backdrop Drush Extension installed out of the box. I recommend Lando to do local development in general and as a great way to isolate dev dependencies and tooling for Backdrop site development. By default Lando will install the latest stable release of the Backdrop Drush extension, but you can point it at any git tag or commit hash. If you wish to live on the bleeding edge and run the Backdrop Drush extension from source you can use this example [.lando.yml](https://github.com/backdrop-contrib/backdrop-drush-extension/wiki/Contributing-code-to-the-Backdrop-drush-extension.) file.
Download drush proper to your BACKDROP_ROOT (the place where your Backdrop code exists. The directory structure should loook something like this:.
If you are using composer to install drush, you can run the following command to require the 8.x version:. To install the Backdrop integration for Drush, clone or download this project into any location that supports Drush commands. The most common location for custom Drush commands such as this is in your user’s home directory. Now switch to a Backdrop site’s directory and try a command! drush cron works well.
mkdir ~/.drush/commands (This may already exist, if so continue.)
