 # pysentistrength
-Python 3 Wrapper for SentiStrength
+Python 3 Wrapper for SentiStrength, reads a single or multiple input with options for binary class or scale output.
+
+Ensure that you have SentiStrength.jar file and SentiStrengthData Language folders, otherwise you can download them from http://sentistrength.wlv.ac.uk/.
+
+## Installation
+
+Pip:
+
+```sh
+pip install pysentistrength
+```
+
+
+## Examples
+
+Example use (single string):
+
+```python
+>>> from sentistrength import PySentiStr
+>>> senti = PySentiStr()
+>>> result = senti.getSentiment('What a lovely day')
+>>> print(result)
+
+... [0.25]
+```
+
+
+Example use (list of strings or pandas Series):
+
+```python
+>>> from sentistrength import PySentiStr
+>>> senti = PySentiStr()
+>>> str_arr = ['What a lovely day', 'What a bad day']
+>>> result = senti.getSentiment(str_arr)
+>>> print(result)
+
+... [0.25,-0.25]
+# OR, if want binary scoring (a score each for positive rating and negativing rating) instead of scale
+>>> result = senti.getSentiment(str_arr, score='binary')
+>>> print(result)
+
+... [(2, -1), (1, -2)]
+```
+
+## Path Setup
+
+Ensure that you have SentiStrength.jar file and SentiStrengthData folder in the same folder, otherwise you can specify the path:
+
+```python
+>>> senti = PySentiStr()
+>>> senti.setSentiStrengthPath = ... # e.g. 'C:\Documents\SentiStrength.jar'
