Learn finding and reading documentation. As every decent library, Primefaces comes along with documentation. You need the Users Guide (PDF). Check chapter 2.3 and on. Assuming you're using JSF 2.0 (who want to start with 1.2 nowadays?), here's an extract of relevance:

2.3.2 JSF 2.0 with PrimeFaces 2.x

Resource Servlet

Although PrimeFaces 2.x uses JSF2 resource APIs to place resources on page, due to limitations of JSF2 resource loading mechanism, PrimeFaces Resource Servlet is required to stream the resources from the bundle. If youʼre running PrimeFaces in a Servlet 3.0 environment like Glassfish V3, this servlet is auto-registered so you donʼt need to configure it manually.

<servlet>
    <servlet-name>Resource Servlet</servlet-name>
    <servlet-class>org.primefaces.resource.ResourceServlet</servlet-class>
</servlet>
    <servlet-mapping>
    <servlet-name>Resource Servlet</servlet-name>
    <url-pattern>/primefaces_resource/*</url-pattern>
</servlet-mapping>

Allowing Text Children

When using Mojarra 2.x, enable allowTextChildren configuration.

<context-param>
    <param-name>com.sun.faces.allowTextChildren</param-name>
    <param-value>true</param-value>
</context-param>

Chapter 2.4 contains some Hello World code. Have a look at it yourself. And the remnant of the guide as well.

Coming back to your statement:

I dont want to change entire frame work.

Primefaces is also not a "complete framework". It's just a JSF component library. You can keep your primary JSF implementation and existing JSF work.

if i'm not mistaken, you should only set namespace, just like you do it for h:... and f:.... Didn't work with prime faces components so i don't know it's namespace.
Example from my project (it uses facelets):
ui:composition xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:ice="http://www.icesoft.com/icefaces/component" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:h="http://java.sun.com/jsf/html" xmlns:c="http://java.sun.com/jstl/core" xmlns:fn="http://java.sun.com/jsp/jstl/functions" xmlns:t="http://myfaces.apache.org/tomahawk"
Just do smth like that: xmlns:prime="primefaces_uri".
