 ### Geting started
 
+- Create .env base on .env.example
+
 - Install Miniconda first
     - `conda create --name vec_engine python=3.6`
     - `conda activate vec_engine`
     - `conda install faiss-gpu cuda90 -c pytorch # For CUDA9.0`
     - `conda install flask`
-    - `pip install flask-restful flask_sqlalchemy`
+    - `pip install flask-restful flask_sqlalchemy flask_script`
+    - `pip install pymysql environs`
