+# Nessie CLI Graph Plugin
+
+A CLI plugin for the Nessie ecosystem that provides simple commands for creating, editing, and visualizing graph structures directly from the terminal.
+
+The plugin allows you to manage **nodes**, **edges**, and their **properties** in a graph using concise CLI commands.
+
+---
+
+## Features
+
+- Create nodes with arbitrary properties
+- Create edges between nodes
+- Modify node and edge properties
+- Delete nodes and edges
+- Reset the current graph
+- Clear the console
+
+---
+
+## Concepts
+### Node
+
+A vertex in the graph identified by an **ID**.
+Nodes can contain arbitrary **key-value properties**.
+
+### Edge
+A connection between two nodes.
+
+Edges also have:
+
+- an **ID**
+- optional **properties**
+
+## Commands
+### Create Node
+
+Create a new node with properties.
+```
+create node --id 1 --property name = John --property age = 30
+```
+
+### Create Edge
+
+Create an edge between two nodes.
+
+Arguments:
+- first node id
+- second node id
+- edge id
+- optional properties
+
+```
+create edge 1 2 --id someEdge --property key=value
+```
+
+### Edit Node
+
+Modify node properties.
+
+Options:
+
+- ```--ch_prop``` – change or add a property
+- ```--del_prop``` – remove a property
+
+```
+edit node --id 1 --ch_prop name = Tom --ch_prop address = "Main street" --del_prop age
+```
+
+### Edit Edge
+
+Modify properties of an edge.
+
+```
+edit edge --id someEdge --ch_prop key = other value
+```
+
+### Delete Edge
+
+Remove an edge from the graph.
+
+```
+delete edge --id someEdge
+```
+
+### Delete Node
+
+Remove a node from the graph.
+
+```
+delete node --id 1
+```
+Note: You can't delete a node if there are incident edges
+
+### Drop Graph
+
+Completely remove the current graph.
+
+```
+drop graph
+```
+
+Clear
+
+Reset the CLI state
+
+```
