 In short, it prints messages or images on your screen, handling the low-level tinkering with both the Linux framebuffer interface, and the i.MX EPDC.

 By default, text rendering relies on bundled fixed cell bitmap fonts ([see this post](https://www.mobileread.com/forums/showpost.php?p=3765426&postcount=31) for a small sampling),
 but thanks to [@shermp](https://github.com/shermp)'s contributions ([#20](https://github.com/NiLuJe/FBInk/pull/20)), you can also rely on full-fledged TrueType/OpenType font rendering!
@@ -89,6 +89,7 @@ The choice of target platform is handled via a simple variable:
 -   Pass `KINDLE=1 LEGACY=1` to make for a FW 2.x Kindle build (`make legacy` does that on a stripped static build). This basically just disables CLOEXEC, which might not be supported on FW 2.x.
 -   Pass `CERVANTES=1` to make for a BQ/Cervantes build (`make cervantes` does that on a stripped static build).
 -   Pass `REMARKABLE=1` to make for a reMarkable build (`make remarkable` does that on a stripped static build).
+-   Pass `POCKETBOOK=1` to make for a PocketBook build (`make pocketbook` does that on a stripped static build).
 
 The same logic is used to allow for a bit of tailoring:
 -   Pass `MINIMAL=1` to make for a build with limited functionality (only fixed cell font rendering, no image rendering, no extra fonts, no OpenType), which yields a much smaller application & library.
