Usage

Shaarli is intended:

to share, comment and save interesting links and news
to bookmark useful/frequent personal links (as private links) and share them between computers
as a minimal blog/microblog/writing platform (no character limit)
as a read-it-later list (for example items tagged readlater)
to draft and save articles/ideas
to keep code snippets
to keep notes and documentation
as a shared clipboard between machines
as a todo list
to store playlists (e.g. with the music or video tags)
to keep extracts/comments from webpages that may disappear
to keep track of ongoing discussions (for example items tagged discussion)
to feed RSS aggregators (planets) with specific tags
to feed other social networks, blogs... using RSS feeds and external services (dlvr.it, ifttt.com ...)

Go to your Shaarli setup and log in
Click the Add Link button
To share text only, do not enter any URL in the corresponding input field and click Add Link
Pick a title and enter your article, or note, in the description field; add a few tags; optionally check Private then click Save
Voilà! Your article is now published (privately if you selected that option) and accessible using its permalink.
