 We're going to create a template project and save it so that we can reuse it for other projects. To do this, we'll start with the GHRD project that comes with the de10-nano CD-ROM and remove a bunch of stuff to make it as simple as possible.
 
+#### Why are we doing this?

+Strictly speaking, you don't need to do all these edits. But it helps to make it as simple as possible to understand what is actually going on under the hood. I've found this approach helpful for my own learning and hope you will find it useful too. It also compiles the design much faster. For me, the original design with everything takes about 15 mins to compile. The trimmed down version takes less than 10 mins.
+
+Of course, you can leave everything as is in the GHRD, in the platform designer as well as in quartus, and it will work perfectly.

    However, the `Base` and `End` addresses for all the 3 components that we added is exactly the same which won't work. Each one needs to have it's own non-overlapping address space.
 
-   For this, we edit the values in the `Base` column to ensure they're not overlapping. I prefer to keep them continuous, but you can give any address as long as it's between `0` and `0x3FF` as provided by the bridge component. Here is what my screen now looks like:
