Installation
============
BotSharp strictly follows the modular design principle and adopts a structure in which views and logic are separated. 
So you can choose the front-end Bot design and management interface. 


Building & Run locally

Building docker image
^^^^^^^^^^^^^^^^^^^^^^^^^^^

If you just want to run BotSharp as a backend NLU engine, you can run it standalone in docker.

::
 
    PS D:\> git clone https://github.com/Oceania2018/BotSharp
    PS D:\> cd BotSharp
    
Build docker image:

::

 PS D:\BotSharp\> docker build -f dockerfiles/DIALOGFLOW.Dockerfile -t botsharp .

Start a container:

::

 PS D:\BotSharp\> docker run --name botsharp -it -p 5000:5000 botsharp

 
Access restful APIs: http://localhost:5000 if you are using RASA response format.

Get a bash shell if you want to update config in the container.

::

 PS D:\BotSharp\> docker exec -it botsharp /bin/bash
