+iA Writer Duospace comes bundled with [iA Writer for Mac and iOS](https://ia.net/writer/buy/)
+
+For in depth explanation of iA Writer Duospace please read our [blog entry](http://ia.net/topics/in-search-of-the-perfect-writing-font/)
+
+This is a modification of IBM's Plex font. 
+The upstream project is [here](https://github.com/IBM/type)
+
+As required by IBM, we named it differently. 
+Please read the licensing file before working with it. 
+
+If you fork or reuse our version, please reference us, too.
+
+## Why `iM Writing` and not `iA Writer`?
+
+What's in a name? The reason for the name change is to comply with the SIL Open Font License (OFL), in partcular the [Reserved Font Name mechanism][SIL-RFN]
+
+Some fonts have parts of their name "reserved" per the [Reserved Font Name mechanism][SIL-RFN]:
+> No Modified Version of the Font Software may use the Reserved Font
+> Name(s) unless explicit written permission is granted by the corresponding
+> Copyright Holder. This restriction only applies to the primary font name as
+> presented to the users.
+
+- The main goals seem to be to: `Avoid collisions`, `Protect authors`, `Minimize support`, and `Encourage derivatives`
+
+See the [Reserved Font Name section][SIL-RFN] for additional information
+
+## Which font?
+
+### TL;DR
+
+* Pick your font family and then select from the `'complete'` directory.
+  * If you are on Windows pick a font with the `'Windows Compatible'` suffix.
+    * This includes specific tweaks to ensure the font works on Windows, in particular monospace identification and font name length limitations
+  * If you are limited to monospaced fonts (because of your terminal, etc) then pick a font with the `'Mono'` suffix.
+    * This denotes that the Nerd Font glyphs will be monospaced not necessarily that the entire font will be monospaced
+
+### Ligatures
+
+By the *Nerd Font* policy, the variant with the `'Mono'` suffix is not supposed to have any ligatures.
+Use the non-*Mono* variants to have ligatures.
+
+### Explanation
+
+Once you narrow down your font choice of family (`Droid Sans`, `Inconsolata`, etc) and style (`bold`, `italic`, etc) you have 2 main choices:
+
+#### `Option 1: Download already patched font`
+
+ * download an already patched font from the `complete` folder
+   * This is most likely the one you want. It includes **all** of the glyphs from all of the glyph sets. Only caution here is that some fonts have glyphs in the _same_ code point so to include everything some had to be moved to alternate code points.
+
+#### `Option 2: Patch your own font`
+
+ * patch your own variations with the various options provided by the font patcher (see each font's readme for full list of combinations available)
+   * This is the option you want if the font you use is _not_ already included or you want maximum control of what's included
+   * This contains a list of _all permutations_ of the various glyphs. E.g. You want the font with only [Octicons][octicons] or you want the font with just [Font Awesome][font-awesome] and [Devicons][vorillaz-devicons]. The goal is to provide every combination possible in this folder.
