+### Protein Data Bank Integrations
+
+- The [pdbe-molstar](https://github.com/molstar/pdbe-molstar) library is the Mol* implementation used by EMBL-EBI data resources such as [PDBe](https://pdbe.org/), [PDBe-KB](https://pdbe-kb.org/) and [AlphaFold DB](https://alphafold.ebi.ac.uk/). This implementation can be used as a JS plugin and a Web component and supports property/attribute-based easy customisation. It provides helper methods to facilitate programmatic interactions between the web application and the 3D viewer. It also provides a superposition view for overlaying all the observed ligand molecules on representative protein conformations.
+
+- [rcsb-molstar](https://github.com/molstar/rcsb-molstar) is the Mol* plugin used by [RCSB PDB](https://www.rcsb.org). The project provides additional presets for the visualization of structure alignments and structure motifs such as ligand binding sites. Furthermore, [rcsb-molstar](https://github.com/molstar/rcsb-molstar) allows to interactively add or hide of (parts of) chains, as seen in the [3D Protein Feature View](https://www.rcsb.org/3d-sequence/4hhb).

+Wipes the `build` and `lib` directories and `.tsbuildinfo` files.
