-(Note: This solution is incomplete. We need to add guid and pubDate
-generation, as this is required for the RSS to be usable)
+We will add a new step in the creation process to create metadata for the
+post that will allow each post to be uniquely identified, as well as
+having a publish date related to them.

 
 We will split the current generator function into generators, and create
 a new generator that will generate an RSS 2.0 file

+## When Adding a Post
+
+When the add function of the blog is triggered, it will shift the posts
+as it currently does and then will generate a new unique ID and take the
+current timestamp. This will be saved in a JSON file in the output
+directory called "metadata.json"
+
+## When Generating Output
+
+When the generate function of the blog is triggered, it will iterate
+over every post. For each of them it will parse the markdown content,
+and the metadata, creating an object of type `tPost` and pushing it
+to an array.
+
+Next, it will iterate from a list of generator functions and call them
+with the source and target directories, and an array containing the `tPost`
+objects. Each generator function will do its work, throwing an exception
+if they encounter an error.

+## The Post Data Structure
+
+This spec introduces a data structure to help generate output.
+
+```
+tPost <Object>
+  +html <String> // The markup of the post
+  +publishedOn <Number> // The timestamp when this post was added
+  +id <String> // The Unique ID for this post
+```
+
+Given that posts won't come in at a high enough rate, and that the
+purpouse is only to help feed readers identify each unique piece of
+content, for this version the `id` will be the same number as the
+`publishedOn`.
