+# Spleen
+
+Spleen is a monospaced bitmap font available in 6 sizes:
+
+- 5x8
+- 6x12
+- 8x16
+- 12x24
+- 16x32
+- 32x64
+
+Each size is provided in the Glyph Bitmap Distribution Format (BDF), and
+release tarballs contain the fonts in the following formats: `PCF`, `PSF`
+(for the Linux console), `OTB`, `OTF`, `.dfont` for macOS users, and `FON`
+for Windows users.
+
+All font sizes contain all ISO/IEC 8859-1 characters (Basic Latin and Latin-1
+Supplement Unicode block), Latin Extended-A characters, as well as Box Drawing,
+Block Elements, and Braille Patterns Unicode blocks, except for the 5x8 and the
+6x12 versions.
+
+Due to character size constraints, the 5x8 version only contains printable
+ASCII characters, the Braille Patterns Unicode block, and light Box Drawing
+characters. Please also note that there is no OpenType version for this size.
+
+As of Spleen 1.8.0, there is now a 6x12 version containing the same Unicode
+blocks as the 5x8 version and the Latin-1 Supplement Unicode block.
+
+Spleen also has support for Powerline symbols out of the box.
+
+The font name is a reference to Baudelaire.

+## Packages
+
+Spleen packages are available for:
+
+- [OpenBSD][9]
+- [NetBSD][10]
+- [FreeBSD][11]
+- [Arch Linux][12]
+- [Void Linux][13]
+- [Nix][14]
+- [Debian][15]
+- [Ubuntu][16]
+- [MacPorts][17]
+
+## Manual installation
+
+### *BSD and Linux
+
+Clone the repository, convert the files to the Portable Compiled Format
+(PCF) using **bdftopcf** and run **mkfontdir** in the directory.
+
+Alternatively, release tarballs provide PCF files for each size.
+
+### macOS
+
+macOS users should use the `.dfont` files provided in the release tarballs.
+
+### Windows
+
+Windows users should use the `.fon` or `.otf` files provided in the release
+tarballs.
+
+## Usage
+
+### *BSD and Linux
+
+Update the font path to include **Spleen**:
+
+	xset +fp /usr/local/share/fonts/spleen/
+
+Update **.Xdefaults** and add one of the following directives:
+
+	xterm*faceName: spleen:pixelsize=8:antialias=false
+	xterm*faceName: spleen:pixelsize=12:antialias=false
+	xterm*faceName: spleen:pixelsize=16:antialias=false
+	xterm*faceName: spleen:pixelsize=24:antialias=false
+	xterm*faceName: spleen:pixelsize=32:antialias=false
+	xterm*faceName: spleen:pixelsize=64:antialias=false
+
+Launch **xterm**.
+
+Ubuntu has bitmap fonts support disabled by default, instructions to enable
+it are available [here][18].
+
+### Linux console
+
+Release tarballs provide PSF files for each size, `setfont` can be used
+to load and set the desired font.
+
+### NetBSD console
+
+NetBSD has .fnt files for each size which can be loaded using wsfontload(8).
+
+For example, to load Spleen 16x32:
+
+	wsfontload -N spleen-16x32 -w 16 -h 32 /usr/share/wscons/fonts/spleen-16x32.fnt
+	wsconsctl -dw font=spleen-16x32
+
+### FreeBSD console
+
+The FreeBSD package contains .fnt files which can be loaded using
+vidcontrol(1).
+
+For example, to load Spleen 16x32:
+
+	vidcontrol -f /usr/local/share/fonts/spleen/spleen-16x32.fnt
+
+### OpenType versions
+
+Spleen release tarballs now contains OTF versions generated automatically
+from the BDF files, using [bdf2sfd][19]. Each font has a different name,
+allowing them to be installed alongside.
+
+They should be used in the exact size specified below, with anti-aliasing
+disabled.
+
+- Spleen 6x12: 9 Pt (12 pixels)
+- Spleen 8x16: 12 Pt (16 pixels)
+- Spleen 12x24: 18 Pt (24 pixels)
+- Spleen 16x32: 24 Pt (32 pixels)
+- Spleen 32x64: 48 Pt (64 pixels)
