Alright, so much for that lets get into the tutorial part.
After you have uploaded and installed the Cashin plugin on your blog goto the setting page by either clicking on the Settings link on the plugins page or the Cashin tab beside the wordpress admin area.
Under Create or Update Unit
You can view your banner or video embed code under View Banner, you need to select the code unit you have created to view it.
To delete a unit, select the code unit you wish to delete under Delete Unit and press the delete unit button.
Now let create a new wordpress post, under the right sidebar of the admin area of your new post you will find the Cashin metabox, now select the code unit you have created and the position you wish it to appear on your post,
under the Content area of the metabox you can select the postion of the embed code, left or right, as well as the count of words before the code start to appear.
If you are inserting the embed code on the sidebar of your blog, you need to do one last step, go to the Widgets area and drag the Cashin widget to the Sidebar panel and that is it.
Now publish your new post and you will see the embed code appears on your blog post. This plugin will get updated every once a a while to fix the bug and include in the new feature!
