+.. class:: infomark
+
+**What it does**
+
+Packmol creates initial MD configurations from input molecules. For example, create a water and urea mixture.
+
+.. class:: infomark
+
+**How it works**
+
+- Select a molecule file type e.g. pdb,xyz
+- Select single molecule from your history (can select multiple)
+- For each molecule:
+   - choose how many molecules to create (number variable)
+   - optionally choose:
+       - molecular radius
+       - how to number the molecules (resnumber variable)
+   - choose one or more placement constraint(s). Each constraint has different parameters:
+       - for example, specify placement inside a cube of size 40 Angstroms placed at the origin
+       - all units are in Angstroms for distances and degrees for angles
+
+.. class:: infomark
+
+**Outputs created**
+
+- A pdb file, view this in Galaxy by clicking on visualise and choosing a viewer. The NGLViewer works well for small molecules.
+- A packmol input script (for debugging and repeatability)
+
+.. class:: infomark
+
+**User guide and documentation**
+
+- Packmol `userguide`_
+- Calculating the number of molecules using the `volume guesser`_
+
+.. class:: infomark
+
+**Known issues**
+
+- fixed constraint only allows 1 atom but this is not set for the user. user has to set this. Job may fail.
