+
+Sprout is an *EXPERIMENTAL* programmable UEFI bootloader written in Rust.
+
+Sprout is in use at Edera now in development environments and is intended to ship to production soon.
+
+The name "sprout" is derived from our company name "Edera" which means "ivy".
+Given that Sprout is the first thing that is inteded to start on an Edera system, the name was apt.
