+## disclaimer
+### this script is not meant to be used as is.
+expect to do *a lot* of modification to fit your needs, as this was created specifically for my site structure and blog markup.

+
+## how it basically works
+1. match files in a specificied directory.
+2. load the DOM of each file.
+3. parse values retrieved from the following strings/HTML elements, as children of a feed `<entry>`:
    -  `<h2>` as `<title>`
    -  the `datetime` attribute of `<time>` as `<updated>`
    -  `<element class="p-summary">` as `<summary>`
    -  `<element class="e-content">` (or `<element class="entry"` for older markup) as `<content>`
    -  `/path/to/blog/entry` as `<id>`/`<link>`
-3. outputs all of the above to `articles.xml` in another directory.
+4. output all of the above in a new file (named `articles.xml`).
 
-for reference, you can check out [the resulting file](https://jasm1nii.xyz/blog/articles/articles.xml) that i've generated myself.
