-The monomer database is a curated, openly-licensed database of 2,488 peptide monomers; canonical and non-canonical amino-acid backbones (α/β/γ/δ/ε), N-/C-terminal caps, and side-chain modifications with physicochemical properties (MW, cLogP, tPSA), usage/availability signals, and structure identifiers (SMILES, InChIKey), for peptide and macrocycle design.
+The Monomer Database is a curated, openly licensed resource for peptide and macrocycle design. 2,488 chemically standardized canonical and non-canonical monomers spanning α/β/γ/δ/ε backbones plus N- and C-terminal caps, with SMILES, InChIKeys, systematic IUPAC names, natural-analogue mapping, computed physicochemical properties (MW, cLogP, tPSA), and commercial-availability signals. Each entry carries a ProteinQure-derived HELM-style monomer shorthand.
 
-This repository contains versioned output formats for the monomer database. The files are generated from the authoritative [`monomer-database-source`](https://github.com/ProteinQure/monomer-database-source) repository and are available for download and archival through [Zenodo]((https://doi.org/10.5281/zenodo.21684533)). [ProteinQure](https://proteinqure.com) is identified as the organizational creator; see [ZENODO.md](ZENODO.md).

+## Interactive Monomer Explorer UI
+
+The Monomer Database can be interactively browsed, explored and searched via the free [Monomer Explorer](https://monomers.proteinqure.com/) hosted by [ProteinQure](https://proteinqure.com). Search the database by name, SMILES, or even a partially remembered name, and retrieve the nearest neighbours of any monomer ranked by Tanimoto similarity. The Chemical Exploration view maps the space around a selected monomer across four regions; close analogues, potential activity cliffs, putative scaffold hops, and the far edge of the space.
