Springer LNCS Proceedings (and Springer Nature Journals)

Verify first (mandatory)

Page limits, anonymization and whether references count are set by the conference, not Springer. Read the CfP.
Springer's author guidelines for proceedings: https://www.springer.com/gp/computer-science/lncs/conference-proceedings-guidelines (templates for LaTeX and Word, plus the author instructions PDF). The class is also on CTAN (https://ctan.org/pkg/llncs).
Springer Nature journals use a different template (sn-jnl). See the journal's submission guidelines.

LaTeX setup (llncs)

Rules from the LNCS guidelines (confirm the current version):

Don't alter the layout, fonts, margins or spacing, and don't add page numbers or custom headers.
Headings are numbered to two levels. Use \subsubsection* or run-in \paragraph below that.
References: splncs04 numbered style. Include DOIs where available. Avoid "et al." in the reference list unless very long.
Figures: vector preferred. Lines and text must be legible at printed size. Colour appears online (print may be grayscale).
Provide ORCIDs via \orcidID{}. Many conferences require them for all authors.

Camera-ready package

Source files (.tex, .bib or .bbl, figures, the llncs class unmodified) and the final PDF.
Signed Consent to Publish / License to Publish form (one per paper, by the corresponding author on behalf of all).
Check that authors, order and affiliations match the conference system exactly.
Supplementary material only if the conference and volume editors allow it.

Double-blind submissions

Remove names, affiliations and ORCIDs. Refer to prior work in the third person, anonymize repository links, and scrub PDF metadata. Some conferences require a specific anonymous paper ID in the header.

Springer Nature journals (sn-jnl)

Use the Springer Nature LaTeX template with the reference style the journal names (numbered, author-year, or discipline-specific). Declarations (funding, competing interests, ethics, consent, data/code availability, author contributions) typically go in a "Declarations" section. Check the journal page.
