| # To add a new provider: | |
| # 1. Register it as a git submodule in this repo: | |
| # git submodule add https://github.com/SAP/<provider-name>.git docs/<provider-name> | |
| # This updates .gitmodules and creates the submodule directory. | |
| # 2. Add an entry to the list below with: | |
| # - name: the submodule directory name (must match the path in .gitmodules) | |
| # - repo: the GitHub repo in "owner/repo" format | |
| # - submodule_path: relative path to the submodule in this repo (i.e. docs/<name>) | |
| # 3. Wire up the provider's docs in docusaurus.config.js and sidebars.js, | |
| # following the existing crossplane-provider-btp pattern. | |
