+that we are currently developing to assist 
+compliant to our model. This interface was
 initially thought as a means for the specification of prompts for SPIRES.
 However, the interface can be exploited independently of that for generating
-LinkML schemas. For the realization of SchemaLink, we decided to start from the
-web app Arrows. Arrows is a very flexible and easy-to-use web tool for drawing
-property graphs. With Arrows, users can specify nodes and edges, assigning them
+LinkML schemas.
+-->
+
+SchemaLink builds upon the functionality of Neo4j's [Arrows](https://arrows.app/), a web tool for drawing and editing property graphs. SchemaLink extends its capabilities to focus on LinkML schemas.
+<!---SchemaLink converts Arrows to a UML-like tool for drawing LinkML schemas from scratch and importing and editing existing
+LinkML schemas specified in ``yaml``. Nodes correspond to classes and edges
+represent relationships between them.
+SchemaLink allows to create and edit classes, relationships, slots and attributes, ontology annotations, descriptions, examples, and customize the graphical style of the schema.
+-->
+Nodes represent classes in the schema, edges define relationships between classes.
+Users can easily add, remove, or update schema items and adjust their properties through an intuitive interface.

+### Features
+
+- **Interactive Schema Creation and Editing**
+  - Define classes, relationships, slots and attributes, and ontology annotations
+  - Add descriptions, examples, and customize graphical styles
+- **Flexible Import and Export**
+  - Import existing LinkML schemas specified in YAML
+  - Export schemas in LinkML, PNG, SVG, JSON
+- **Applications**
+  - Graphically representing relationships between bio-entities grounded in OBO ontologies
+  - Performing named entity recognition (NER) and relation extraction (RE) tasks using the [OntoGPT](https://github.com/monarch-initiative/ontogpt) package

+With Arrows, users can specify nodes and edges, assigning them
 names, types, and additional properties. Moreover, it offers facilities for
 loading graphs (locally or from cloud infrastructures), exporting in different
 forms (PNG, SVG, JSON, Cypher), easily adding/removing/updating nodes, edges,
 subgraphs, and their properties, and trivially changing the visual aspects of
-the generated graph. In our case, Arrows is used as a UML-like tool for
-conceptual schema design where nodes correspond to classes, while edges

+Even if the “visual quality” of the generated diagram
 is worse than the one obtained by widely adopted UML-like tools, its simplicity
 of use makes Arrows a very promising tool for sketching conceptual schemas.
-Several are the features that have been integrated into SchemaLink for importing
-LinkML yaml file, drawing schemas, and exporting them.
