+Python 3.6+ required. Create `mergin/deps` folder where [geodiff](https://github.com/lutraconsulting/geodiff) lib is supposed to be and install dependencies:
+    
+    mkdir -p mergin/deps
     pipenv install --dev --three
+    pipenv run pip install -r <(pipenv lock -r | grep pygeodiff) --target mergin/deps
 
 For using mergin client with its dependencies packaged locally run:
 
     pip install wheel
     python3 setup.py sdist bdist_wheel
     mkdir -p mergin/deps
     pip wheel -r mergin_client.egg-info/requires.txt -w mergin/deps
-
+    unzip mergin/deps/pygeodiff-*.whl -d mergin/deps
