Next you'll need to install all your favourite plugins.
If your installation contains any pre-installed plugins then you may want to delete most of those. I mean delete plugins like Akismet or Hello Dolly. If your host has pre-installed plugins that they require for say caching or security, you should keep those. For example I host with GridPane and they automatically install Nginx Helper and Redis Object Cache plugins and I of course keep those caching plugins installed.
You will have your own preferred plugin list. My recommended WordPress plugins are here in case you want to do as I do.
Activate the plugins you need during development and put in all necessary license keys.
