You can change Business Central by installing apps that add functionality, change behaviour, or give you access to 3rd party online services.
AL-Go for GitHub is a set of GitHub templates and actions, which can be used to setup and maintain DevOps processes for your Business Central AL projects
I used AL-Go for GitHub to create a Business Central per-tenant extension (PTE) with VS Code.
(Notice that you can upload a Per Tenant Extension (PTE) to Microsoft Dynamics Business Central using the Business Central Extension Management page.)
I used the AL-Go-PTE GitHub template repository https://github.com/microsoft/AL-Go-PTE
Prerequisites: A GitHub account, A Windows machine, VS-Code (with AL and PowerShell extensions installed), and Docker installed locally.
