+## Troubleshooting
+
+### Installation error: missing biotite module
+
+In some Linux systems, trying to install `Molecular Nodes` through the `Get Extensions` panel in Blender may lead to the following error:
+
+```bash
+Report: Error
+No module named 'biotite.structure.bonds' 
+```
+This is likely due to a mismatch in the Python versions installed in your system and in what Blender expects (see issue [#629](https://github.com/BradyAJohnston/MolecularNodes/issues/629)). 
+
+To avoid this issue, try installing Blender through a self-contained package system such as Flatpack or Snap. These package managers usually need to be installed and/or activated in your system.
+
+For example, after installing Snap in Fedora 40, you can install Blender through Snap with the command which solves the `biotite` dependency error.
+
+```bash
+sudo snap install blender --classic
+```
