 ```
 
 ## Using
+A simple example:
 ```JavaScript
 import Container from 'simple-container';
 
-var container = new Container({});
-container.create();
+var container = new Container();
+
+/* Create the container */
+container.create('postgres:alpine');
+
+/* Start the container */
+container.start();
+
+/* Stop and destroy the container */
+container.destroy();
+```
+
+### Remote connection
+By default, the local service is used.
+
+For example, if you want to use connection settings:
+```JavaScript
+var container = new Container({
+    host: '127.0.0.1',
+    port: 3000
+});
+```
+
+Examples and details in
+[the documentation](https://github.com/apocas/dockerode#getting-started).
+
+### Creating a container
+You can create a container in two ways.
+
+A simple way - to specify the name of the image:
+```JavaScript
+container.create('hello-world:latest');
+```
+
+Another way - to provide an object with parameters:
+```JavaScript
+container.create({
+    Image: 'postgres:alpine',
+    Env: ['POSTGRES_PASSWORD = password'],
+    Ports: [{
+        IP: '0.0.0.0',
+        PrivatePort: 5432,
+        PublicPort: 5432,
+        Type: 'tcp'
+    }]
+});
 ```
 
+Examples and details in
+[the documentation](https://github.com/apocas/dockerode#manipulating-a-container).
+
+An additional example of obtaining a private image:
+```JavaScript
+var auth = {
+    username: 'username',
+    password: 'password',
+    email: 'email@example.org',
+    serveraddress: 'https://index.docker.io/v1'
+};
+
+container.create({
+    Image: 'project:latest',
+    authconfig: auth
+});
+```
+
+Details in
+[the documentation](https://github.com/apocas/dockerode#pull-from-private-repos).
+
+## Debugging
+Use the `DEBUG` variable with the `container` option.
