The new link target ../docs/deployment.md will likely still be broken when this snippet is included into docs/index.md / docs/installation.md via pymdownx.snippets, because MkDocs resolves relative links relative to the including page (in docs/), not the snippets/ directory. From docs/index.md, ../docs/deployment.md points outside the docs root. Consider linking to deployment.md instead (same directory as the including pages).
