-# python-ooui
-Port of ooui.js to Python
+# Python OOUI
 
-## Testing
+Python OOUI (Open Object User Interface) is a Python port of ooui.js, providing powerful tools for data visualization and processing.
 
-```shell
+## Features
+
+- **Graph Processing**: Create line charts, bar charts, pie charts, and indicators
+- **Tree Views**: Handle structured data with advanced filtering and conditional formatting  
+- **Data Helpers**: Utilities for domain parsing, condition evaluation, and data aggregation
+- **XML Parsing**: Parse XML-based graph and tree definitions
+- **Cross-Platform**: Compatible with Python 2.7+ and Python 3.x
+
+## Quick Start
+
+### Installation
+
+```bash
+pip install ooui
+```
+
+### Basic Usage
+
+```python
+from ooui.graph import parse_graph
+from ooui.tree import parse_tree
+
+# Create a line chart
+graph_xml = '''
+<graph type="line" string="Sales Trend">
+    <field name="date" type="date"/>
+    <field name="amount" type="float" operator="sum"/>
+</graph>
+'''
+graph = parse_graph(graph_xml)
+
+# Create a tree view
+tree_xml = '''
+<tree string="Customer List" editable="top">
+    <field name="name"/>
+    <field name="email"/>
+    <field name="status"/>
+</tree>
+'''
+tree = parse_tree(tree_xml)
+```

+## Key Components
+
+### Graph Processing
+```python
+from ooui.graph import parse_graph
+
+# Support for multiple chart types
+graph = parse_graph(xml_definition)
+result = graph.process(data, fields)
+```
+
+### Tree Views
+```python
+from ooui.tree import parse_tree
+
+# Structured data with conditional formatting
+tree = parse_tree(xml_definition)
+conditional_fields = tree.fields_in_conditions
+```
+
+### Condition Evaluation
+```python
+from ooui.helpers import ConditionParser
+
+parser = ConditionParser("red:amount < 100;green:amount >= 100")
+result = parser.eval({'amount': 150})  # Returns "green"
+```
+
+### Domain Parsing
+```python
+from ooui.helpers import Domain
+
+domain = Domain("[('active', '=', True), ('age', '>', 18)]")
+parsed = domain.parse({'user_id': 42})
+```
+
+## Development
+
+### Setting Up Development Environment
+
+```bash
+# Clone the repository
+git clone https://github.com/gisce/python-ooui.git
+cd python-ooui
+
+# Install in development mode
 pip install -e .
+
+# Install development dependencies
 pip install -r requirements-dev.txt
+```
+
+### Running Tests
+
+```bash
+# Run all tests
 mamba
+
+# Tests use mamba (BDD testing framework)
+# See spec/ directory for test specifications
 ```
