You can also use the sync functionality built into Skate to have the bookmarks distributed across multiple machines (though that may not be as useful as it may seem).

 This powershell function allows you to bookmark a path and then effortlessly return to it at a later time.
 
+## Philosophy
+
+Imagine having a short list of bookmarks available in your CLI. You have one for your current project, one for your other current project, one for your Neovim setup, one for this thing you jave to do this week and never have to touch again, and etc. Imagine being able to jump between them with one simple command.
+
+Now imagine you only have 10 bookmark slots, so you have to be judicious as to what you bookmark, and how you maintain the list, so that it continues being useful.
+
+### Why not use symlinks?
+
+Symlinks tend to be permanent. They are easy to set up, but equally easy to never delete, so you end up with a lot of clutter in your home directory. A limited list of 10 bookmarks forces you to actively prune it, and make decisions about to what should be on it, based on how often you use it.
