hi,

the procedure may depend on the information you have, but please start checking this tutorial [HADDOCK 2.4 CASP-CAPRI T70 ab-initio docking tutorial – Bonvin Lab](https://www.bonvinlab.org/education/HADDOCK24/HADDOCK24-CASP-CAPRI-T70/) which explains how to perform _ab-initio_ (i.e. with no prior information) docking of symmetrical homo-multimers. If you have some information on the interface consider adding it to the docking by means of ambiguous interaction restraints (check other tutorials such as [HADDOCK2.4 basic protein-protein docking tutorial – Bonvin Lab](https://www.bonvinlab.org/education/HADDOCK24/HADDOCK24-protein-protein-basic/))

In case you prefer to use HADDOCK3 (command line-only), have a look at this tutorial (for a symmetric homotrimer): [haddock3/examples/docking-protein-homotrimer/docking-protein-homotrimer-test.cfg at main · haddocking/haddock3 · GitHub](https://github.com/haddocking/haddock3/blob/main/examples/docking-protein-homotrimer/docking-protein-homotrimer-test.cfg)

Hope it helps.  
Marco
