 == Supporting Projectile
 
-NOTE: A bit of trivia for you - Projectile was my very first open-source project and
- it has a very special place in my heart!
+I've started working on Projectile in 2011 and I've supporting it ever since. It slowly grew from an obscure
+project with a single user to one of the most popular packages in the realm of Emacs. It's a fun project,
+but it also requires a lot of work.
