 This will produce a hash which is to be placed in the `password` field in `username.ini`. Ensure that the `encryption` field is set to `password_hash`.

-Both Online or Offline
-----------------------
-The built-in editor found in the admin panel, also provides you the ability to write to Markdown files offline by uploading them (see naming convention below) into the `content/username/blog/category/type/`:
-
-* `username` must match `config/users/username.ini`.
-* `category` must match the `category.md` inside `content/data/category/category.md` except the `uncategorized` category.
-* `type` is the content type. Available content type `post`, `video`, `audio`, `link`, `quote`.
-
-For static pages you can upload it to the `content/static` folder.
-
-Category
---------
-The default category is `Uncategorized` with slug `uncategorized` and you do not need to creating it inside `content/data/category/` folder. But if you write it offline and want to assign new category to specific post you need to creating it first before you can use those category, example `content/data/category/new-category.md` with the following content:
-
-```html
-<!--t New category title t-->
-<!--d New category meta description d-->
-
-New category info etc.
-````
-The slug for the new category is `new-category` (htmly removing the file extension). And for full file directory:
-````
-content/username/new-category/post/file.md
-````
-
-File Naming Convention
-----------------------
-When you write a blog post and save it via the admin panel, HTMLy automatically create a .md file extension with the following name, example:
-
-````
-2014-01-31-12-56-40_tag1,tag2,tag3_databaseless-blogging-platform-flat-file-blog.md
-````
-
-Here's the explanation (separated by an underscore):
-
-- `2014-01-31-12-56-40` is the published date. The date format is `yyyy-mm-dd-hh-mm-ss`
-- `tag1,tag2,tag3` are the tags, separated by commas
-- `databaseless-blogging-platform-flat-file-blog` is the URL
-
-For static pages, use the following format:
-
-````
-content/static/about.md
-````
-
-In the example above, the `/about.md` creates the URL: `www.yourblog.com/about`
-
-Thus, if you write/create files offline, you must name the .md file in the format above.
-
-For static subpages, use the following format:
-
-````
-content/static/about/me.md
-````
-
-This will create the URL: `www.yourblog.com/about/me`
-
-Content Tags
--------------
-If you are writing offline, you need specify the content tags below:
-
-**Title**
-```html
-<!--t Title t-->
-````
-
-**Meta description**
-```html
-<!--d The meta description d-->
-````
-
