+## GeoTextConfiguration
+
+```python
+class GeoTextConfiguration(BaseModel)
+```
+
+GeoText configuration
+
+**Arguments**:
+
+- `use_demo_data` _bool_ - load demo data or not, default True
+- `case_sensitive` _bool_ - case sensitive lookup, default True
+

+
+## GeoText
+
+```python
+class GeoText(LookupDataPool)
+```
+
+Extract LookupData from input text
+
+GeoText inherits from LookupDataPool. It iterates through
+a LookupDataPool and interfaces flashtext.KeywordProcessor
+to extract keywords from an input text. It parses the result of
+flashtext.KeywordProcessor.extract_keywords() by counting the
+occurances of a LookupData point and optionally lists the
+span info.
+
+**Example**:
+
+```python
+    from flashgeotext.geotext import GeoText
+
+    geotext = GeoText()
+
+    input_text = '''Shanghai. The Chinese Ministry of Finance in Shanghai said that China plans
+                    to cut tariffs on $75 billion worth of goods that the country
+                    imports from the US. Washington welcomes the decision.'''
+
+    geotext.extract(input_text=input_text, span_info=True)
+    >> {
+        'cities': {
+            'Shanghai': {

+                },
+            'Washington, D.C.': {
+                'count': 1,

+#### \_\_init\_\_
+
+```python

+
+```python
+def extract(input_text: str, span_info: bool = True) -> dict

+
+**Arguments**:
+
+- `input_text` _str_ - String to extract LookupData from.
+- `span_info` _bool_ - Optionally, return span_info. Defaults to True.
+
+
+**Returns**:
