-
-The `exec-script` command is used to execute a user script for an index that has already been imported to Elasticsearch with the `index` command. Note that the documents will not be reset to their default state before each execution as the `index` command does: if you make undesired changes to the documents by accident, you will need to run `index` again to revert to the original state.

 ## User scripts
 
-*This document is under construction, more in-depth guide coming soon*
+User scripts are used to augment your sist2 index with additional metadata, neural network embeddings, tags etc.
+
+
+Since version 3.2.0, user scripts are written in Python, and are ran against the sist2 index file. User scripts do not 
+need a connection to the search backend.
+
+You can create a user script based on a template from the sist2-admin interface:
+
+![sist2-admin-scripts](sist2-admin-scripts.png)
+
+User scripts leverage the [sist2-python](https://github.com/simon987/sist2-python) library to interface with the
+index file*. You can find sist2-python documentation and examples
+here: [sist2-python.readthedocs.io](https://sist2-python.readthedocs.io/).
+
+If you are not using the sist2-admin interface, you can run user scripts manually from the command line:
+
+```
+pip install git+https://github.com/simon987/sist2-python.git
+
+python my_script.py /path/to/my_index.sist2
+```
+
+\* It is possible to manually update the index using raw SQL queries, but the database schema is not stable and
+can change at any time; it is recommended to use the more stable sist2-python wrapper instead.

+<details>
+  <summary>Legacy user scripts (sist2 version < 3.2.0)</summary>
 
 During the `index` step, you can use the `--script-file <script>` option to
 modify documents or add user tags. This option is mainly used to
 implement automatic tagging based on file attributes.
