 ### Breaking
 - Remove `toc` variable in section/page context and pass it to `page.toc` and `section.toc` instead so they are
 accessible everywhere
+- [Slugification](https://en.wikipedia.org/wiki/Slug_(web_publishing)#Slug) of page paths is now optional. By default, every path will be slugified as it is happening right now.
+To keep non-ASCII characters,  set `slugify_paths = true` in your config.
 
 ### Other
 - Add zenburn syntax highlighting theme

+Either way, these proposed path will be sanitized before being used.
+If `slugify_paths` is enabled in the site's config - the default - paths are [slugified](https://en.wikipedia.org/wiki/Clean_URL#Slug). 
+Otherwise, a simpler sanitation is performed, outputting only valid NTFS paths. 
+The following characters are removed: `<`, `>`, `:`, `/`, `|`, `?`, `*`, `#`, `\\`, `(`, `)`, `[`, `]` as well as newlines and tabulations. 
+Additionally, trailing whitespace and dots are removed and whitespaces are replaced by `_`.
+
+**NOTE:** To produce URLs containing non-English characters (UTF8), `slugify_paths` needs to be set to `false`.
+
+### Path from frontmatter
+
+The output path for the page will first be read from the `slug` key in the page's frontmatter.
+
+**Example:** (file `content/zines/mlf-kurdistan.md`)
+
+```
++++
+title = "Le mouvement des Femmes Libres, à la tête de la libération kurde"
+slug = "femmes-libres-libération-kurde"
++++
+This is my article.
+```
+
+This frontmatter will output the article to `[base_url]/zines/femmes-libres-libération-kurde` with `slugify_paths` disabled, and to `[base_url]/zines/femmes-libres-liberation-kurde` with `slugify_enabled` enabled.
+
+### Path from filename
+
+When the article's output path is not specified in the frontmatter, it is extracted from the file's path in the content folder. Consider a file `content/foo/bar/thing.md`. The output path is constructed:
+- if the filename is `index.md`, its parent folder name (`bar`) is used as output path
+- otherwise, the output path is extracted from `thing` (the filename without the `.md` extension)
+
+If the path found starts with a datetime string (`YYYY-mm-dd` or [a RFC3339 datetime](https://www.ietf.org/rfc/rfc3339.txt)) followed by an underscore (`_`) or a dash (`-`), this date is removed from the output path and will be used as the page date (unless already set in the front-matter). Note that the full RFC3339 datetime contains colons, which is not a valid character in a filename on Windows.
+
+The output path extracted from the file path is then slugified or not depending on the `slugify_paths` config, as explained previously.
+
+**Example:** The file `content/blog/2018-10-10-hello-world.md` will generated a page available at will be available at `[base_url]/hello-world`.

 Zola has built-in support for taxonomies.
 
-The first step is to define the taxonomies in your [config.toml](@/documentation/getting-started/configuration.md).
+## Configuration
 
 A taxonomy has five variables:
 
@@ -16,21 +16,48 @@ For example the default would be page/1.
 - `rss`: if set to `true`, an RSS feed will be generated for each term.
 - `lang`: only set this if you are making a multilingual site and want to indicate which language this taxonomy is for
 
-Once this is done, you can then set taxonomies in your content and Zola will pick
-them up:
+**Example 1:** (one language)
+
+```toml
+taxonomies = [ name = "categories", rss = true ]

+## Using taxonomies
+
+Once the configuration is done, you can then set taxonomies in your content and Zola will pick them up:

+**Example:**
 
 ```toml

+## Output paths
+
+In a similar manner to how section and pages calculate their output path:
+- the taxonomy name is never slugified
+- the taxonomy entry (eg. as specific tag) is slugified when `slugify_paths` is enabled in the configuration
+
+The taxonomy pages are then available at the following paths:
 
 ```plain
-$BASE_URL/$NAME/
-$BASE_URL/$NAME/$SLUG
+$BASE_URL/$NAME/ (taxonomy)
+$BASE_URL/$NAME/$SLUG (taxonomy entry)
