+Multisite Test
+==============
+
+Example of multiple sites with one Django source.
+
+This is just an example project to illustrate Django's multisite feature.
+
+
+## Run local server
+
+We use `docker-compose` to launch development server. The command is wrapped
+inside `Makefile`, so you can just type:
+
+```
+$ make up
+```
+
+Then, open `http://127.0.0.1:8000` or `http://site1.local:8000` in the browser
+to access the server. This makes you can see the contents of default site 1.
+If you want to visit site 2, just try `http://site2.local:8000`. You can see
+different contents depending on the address you typed.
+
+If you want to re-build the docker images later, you can use another make
+command.
+
+```
+$ make build
+```
