+# Lineage View 
+
+The **Lineage View** panel is a feature of the Datacoves VSCode extension that provides a visual representation of the lineage of your project. This tool helps you quickly understand how data flows between models, sources, and downstream dependencies within your dbt project.
+
+## What is the Lineage View?
+
+The Lineage View displays a graph of your dbt model's relationships, showing both upstream and downstream dependencies. This visualization makes it easy to:
+
+- See which sources and models feed into your current model
+- Identify all models and reports that depend on your current model
+- Understand the impact of changes to a model across your project
+
+## Usage
+
+The basic usage of Lineage View consists of the following steps:
+
+1. **Open a dbt model or yml file** in your VSCode workspace.
+2. Locate the **Lineage View** panel, typically found in the lower panel (alongside Terminal, Output, Datacoves)
+3. The panel will automatically display the lineage graph for the currently sql or yml file.
+
+### Additional features
+
+In addition to seeing your model(s) lineage, you can also:
+
+- **Single-click** on a node to open the SQL file.
+- **Double-click** on a node to open the YML file.
+- **Right click** a node and perform a dbt action(run, test, compile, open files, etc)
+
+You can also look up other dbt models and change the parent and child nodes displayed using one of the following:
+  -  `{n}+my_model`
+  -  `my_model+{n}`
+  -  `{n}+my_model+{n}`
+

+
+## Configuration
+
+Lineage Panel has 3 configurable settings. As with any VSCode setting, these can be [overridden](/how-tos/vscode/override) in the `settings.json` file located in `workspace/.vscode/settings.json`:
+
+- Default Expansion (`dbt.lineage.defaultExpansion`: number): How many nodes should expand by default for the currently-opened model.
