On I was thinking of: when developing websites there’s all sort of data regarding hosting, domains, databases, FTP / email accounts, control panel accounts, etc. (usernames, passwords, urls, ports, protocols, etc).
It would be great if one had a markdown template like, for example:
#Website %websitename%
Dear %clientname%
You can access the control panel of your website by visiting %cpaneladdress% and login with the credentials %cpanelusername% / %cpanelpassword%.
Those placeholders could be stored and edited as custom metadata of the current database (Custom metadata per database) and one would just need to edit those and export the markdown to PDF (with custom stylesheet) and get a good-looking and practical user manual.
