 ## Example
 
 ``` javascript
-import pgrx from 'pg-reactive';
+import PgRx from 'pg-reactive';
 
-let db = new pgrx('postgres://postgres@$localhost/tester');
+const db = new PgRx('postgres://postgres@$localhost/tester');

-* `pgrx` Class
-
-  Database connection class. It can be initialized with a database url like
-
-  ```
-  pg://user:password@host:port/database
-  ```
-
-  or a crednetial object:
-
-  ``` json
-  {
-    "user": "postgres",
-    "database": "tester",
-    "password": "",
-    "host": "localhost",
-    "port": 5432
-  }
-  ```
-
-* `pgrx.end()` Function
-
-  End the current database connection.
-
-* `pgrx.query(sql[, values])` Function
-
-  Run a query with optional values. This function supports the query formating of [pg](https://github.com/brianc/node-postgres/wiki/Client#parameterized-queries) and you can construct the query like
-
-  ``` javascript
-  pgrx.query('SELECT id FROM user WHERE name = $1::text', ['Tom']);
-  ```
-
-  It will return an observable that emits every row of the query result.
-
-* `pgrx.tx(callback)` Function
-
-  Run queries within a transaction. The callback function receives an object that has a `query()` function to run queries within the transaction and return an observable. To pass the data to the following operator, return an observable in the callback function.
-
-  ``` javascript
-  pgrx.tx((t) => {
-    let insert1 = t.query('INSERT INTO user (name) VALUES ($1::text) RETURNING id;', ['Tom']);
-    let insert2 = t.query('INSERT INTO user (name) VALUES ($1::text) RETURNING id;', ['Joe']);
-
-    return insert1.concat(insert2);
-  })
-  .subscribe((row) => console.log(row));
-  ```
-
-  No data will be emitted if any query in a transaction fails.
