+
+## Online demo
+
+Deployed site: https://forum.casbin.com/
+
+## Architecture
+
+Casnode contains 2 parts:
+
+Name | Description | Language | Source code
+----|------|----|----
+Frontend | Web frontend UI for Casnode | Javascript + React | https://github.com/casbin/casnode/tree/master/web 
+Backend | RESTful API backend for Casnode | Golang + Beego + MySQL | https://github.com/casbin/casnode 
+
+## Installation
+Casnode uses Casdoor to manage members. So you need to create an organization and an application for Casnode in a Casdoor instance.
+### Necessary configuration 
+
+#### Get the code
+
+```shell
+go get github.com/casbin/casnode
+go get github.com/casdoor/casdoor
+```
+or
+```shell
+git clone https://github.com/casbin/casnode
+git clone https://github.com/casdoor/casdoor
+```
+
+#### Setup database
+
+Casnode will store its users, nodes and topics informations in a MySQL database named: `casnode`, will create it if not existed. The DB connection string can be specified at: https://github.com/casbin/casnode/blob/master/conf/app.conf
+
+```ini
+dataSourceName = root:123@tcp(localhost:3306)/
+```
+
+Casnode uses XORM to connect to DB, so all DBs supported by XORM can also be used.
+
+#### Run casnode
+  - Configure and run casnode by yourself. If you want to learn more about casnode, you see [casnode installation](https://casnode.org/docs/installation).
+  - Install casnode using docker. you see [installation by docker](https://casnode.org/docs/Docker).
+  - Install casnode using BTpanel. you see [installation by BTpanel](https://casnode.org/docs/BTpanel).
+  - Open browser:
+
+    http://localhost:3000/
+
+### Optional configuration 
+
+#### Setup your forum to enable some third-party login platform
+
+  Casnode uses Casdoor to manage members. If you want to log in with oauth, you should see [casdoor oauth configuration](https://casdoor.org/docs/provider/OAuth).
+
+#### OSS, Mail, and SMS services
+
+  Casnode uses Casdoor to upload files to cloud storage, send Emails and send SMSs. See Casdoor for more details.
+
+#### Github corner
+
+We added a Github icon in the upper right corner, linking to your Github repository address.
+You could set `ShowGithubCorner` to hidden it.
+
+Configuration:
+
+```javascript
+export const ShowGithubCorner = true
+
+export const GithubRepo = "https://github.com/casbin/casnode" //your github repository
+```
