+# Description LinkML conversion
+
+Generate `description.linkml.yml` from the local RDFS and SHACL Turtle files:
+
+```sh
+python3 scripts/rdfs_shacl_to_linkml.py
+```
+
+By default, the script reads:
+
+- `description/description.rdfs.ttl`
+- `description/description.shacl.ttl`
+
+and writes:
+
+- `scripts/description.linkml.yml`
+
+You can override the paths:
+
+```sh
+python3 scripts/rdfs_shacl_to_linkml.py \
+  --rdfs description/description.rdfs.ttl \
+  --shacl description/description.shacl.ttl \
+  --output scripts/description.linkml.yml
+```
+
+Multiple RDFS or SHACL files can be supplied. They are concatenated in the order given:
+
+```sh
+python3 scripts/rdfs_shacl_to_linkml.py \
+  --rdfs description/description.rdfs.ttl rights/rights.rdfs.ttl \
+  --shacl description/description.shacl.ttl rights/rights.shacl.ttl
+```
+
+The converter is dependency-free and tailored to the Turtle style used in these files. It is not a general-purpose RDF or SHACL parser.
