 This is how I built custom fonts for [[https://github.com/olikraus/ucglib | Ucglib]]/[[https://github.com/olikraus/Ucglib_Arduino | Ucglib_Arduino]] on Linux.
+Ucglib uses [[https://en.wikipedia.org/wiki/Glyph_Bitmap_Distribution_Format | BDF]] fonts as a source. The basic process to convert a typical font file for use in Ucglib is:
+  * Convert an OTF or TTF font to BDF format using ''[[ http://sofia.nmsu.edu/~mleisher/Software/otf2bdf/ | otf2bdf ]]'', ''[[http://sofia.nmsu.edu/~mleisher/Software/gbdfed/ | gbdfed]]'', or ''[[https://fontforge.github.io/en-US/ | fontforge]]''. //Check font licenses!//
+  * Use ''bdconf'' to convert the BDF format to C.
+  * Add the new code to the appropriate Ucglib file.
+Details are provided below.
 ===== Requirements =====
-Ucglib uses [[https://en.wikipedia.org/wiki/Glyph_Bitmap_Distribution_Format | BDF]] fonts as a source. You will need:
-  * OTF and TTF files of the fonts you want to convert. //Check licenses!//
+==== Getting otf2bdf and fontforge ====
-  * A way to convert these to BDF format: ''[[ http://sofia.nmsu.edu/~mleisher/Software/otf2bdf/ | otf2bdf ]]'', ''[[http://sofia.nmsu.edu/~mleisher/Software/gbdfed/ | gbdfed]]'', or possibly ''[[https://fontforge.github.io/en-US/ | fontforge]]''
-  * A way to convert BDF files to the C structures used in Ucglib: ''bdfconv'', which you will build below.
+''%%otf2bdf%%'', ''%%gbdfed%%'' and ''%%fontforge%%'' are available in many Linux distributions.
 ==== Building bdfconv ====
-Download the [[https://github.com/olikraus/ucglib|Ucglib repository]], move into ''%%tools/font/bdfconv%%'' and
+You will probably have to build ''%%bdfconv%%'' yourself. Download the [[https://github.com/olikraus/ucglib|Ucglib repository]], move into ''%%tools/font/bdfconv%%'' and

 View the result using ''%%gbdfed%%'' or ''%%fontforge%%''.
+Once the font is in BDF format, you can use ''%%fontforge%%'' to edit it, which might include removing unused characters or tweaking bitmaps.
