 [Golang](https://golang.org/) implementation of the [RSS feed](https://en.wikipedia.org/wiki/RSS) parser explicitly for the [PreDB.me](https://predb.me/) website (uses minimal Atom 2.0 feed type without pub date).
 
 ## Technical details
 
 1. HTTP GET https://predb.me/?rss=1
+![xml_document_tree.png](img/xml_document_tree.png)
 2. Transform `<rss xmlns:atom="http://www.w3.org/2005/Atom" version="2.0"> ... </rss>` into XML struct:
    - 1x top item `<channel> ... </channel>` contains
    - 40x nested `<item> ... </item>` items which each contain
-   - 1x `<title> ... </title>`
+   - 1x `<title> ... </title>` for each item
 3. Create a list of the 40 titles, while caching the information of the latest title (first `<title>` is the latest)
 4. Run steps 1.-3. every `X` minutes
