 # flask-swagger
 A Swagger 2.0 spec extractor for Flask
 
+You can now specify base path for yml files:
+```
+app = Flask(__name__)
+
+@app.route("/spec")
+def spec():
+    base_path = os.path.join(app.root_path, 'docs')
+    return jsonify(swagger(app), from_file_keyword="swagger_from_file", base_path=base_path)
+```
+and use relative paths:
+```
+@app.route('/test', methods=['POST'])
+def login():
+    """
+    swagger_from_file: test.yml
+    """
+```
