How to Add a New core

[Sohan Kalsariya]

Hello All.
How do i add a new core in Solr ?
My solr directory is :
/usr/share/solr-4.6.1/example/solr
And it is having only one collection i.e. collection1
Now to add the new core I added a directory collection2 and in that I
created 2 more directory.
/conf & /lib
Now my what should be the entry in solr.xml file?

<solr>

  <solrcloud>
    <str name="host">${host:}</str>
    <int name="hostPort">${jetty.port:8983}</int>
    <str name="hostContext">${hostContext:solr}</str>
    <int name="zkClientTimeout">${zkClientTimeout:15000}</int>
    <bool name="genericCoreNodeNames">${genericCoreNodeNames:true}</bool>
  </solrcloud>

  <shardHandlerFactory name="shardHandlerFactory"
    class="HttpShardHandlerFactory">
    <int name="socketTimeout">${socketTimeout:0}</int>
    <int name="connTimeout">${connTimeout:0}</int>
  </shardHandlerFactory>

</solr>


What to add in this file to register the new core?
Please guide me.
