+This directory contains PNGs built from a couple of open source fonts: the
+sans serif Liberation Mono Regular and the serif Luxi Mono Regular, in 12-,
+14, and 24-point versions. All of these font files have anti-aliasing (aka
+font smoothing) applied. The directory also includes the original rEFInd
+font, which is a 12-point un-smoothed Times-like font.
+
+If you want to create your own fonts, you can do so. If you're using Linux,
+the mkfont.sh script will convert an installed MONOSPACE font into a
+suitable format. You can use it like this:
+
+./mkfont.sh Liberation-Mono-Italic 14 -1 liberation-mono-italic-14.png
+
+The result is a PNG file, liberation-mono-italic-14.png, that you can copy
+to your rEFInd directory and load with the "font" token in refind.conf, as
+in:
+
+font liberation-mono-italic-14.png
+
+The mkfont.sh script takes four arguments:
+
+- The font name. Type "convert -list font | less" to obtain a list of
+ fonts available on your computer. Note, however, that rEFInd requires
+ MONOSPACED (fixed-width) fonts, and most of the fonts installed on most
+ computers are variable-width.
+
+- The font size in points.
+
+- A y offset. Many fonts require an adjustment up (negative values), or
+ occasionally down (positive values) to fit in the PNG image area. You'll
+ have to use trial and error to get this to work.
+
+- The output filename.
+
+I recommend checking the PNG file in a graphics program like eog before
+using it. Note that the font files should have an alpha layer, which many
+graphics program display as a gray-and-white checkered background.
+
+If you're not using Linux, or if you want to use some other method of
+generating fonts, you can do so. The font files must be in PNG format (the
+BMP format doesn't support an alpha layer, which is required for proper
+transparency). They must contain glyphs for the 95 characters between ASCII
+32 (space) and ASCII 126 (tilde, ~), inclusive, plus a 96th glyph that
+rEFInd displays for out-of-range characters. To work properly, the
+characters must be evenly spaced and the PNG image area must be a multiple
+of 96 pixels wide, with divisions at appropriate points. In theory, you
+should be able to take a screen shot of a program displaying the relevant
+characters and then crop it to suit your needs. In practice, this is likely
+to be tedious.
