Quit your editor/program. Unzip and open the folder.

* **[Instructions for Windows](https://www.microsoft.com/en-us/Typography/TrueTypeInstall.aspx)**
* **[Instructions for macOS](http://support.apple.com/kb/HT2509)**
  * Standard distribution in Homebrew: `brew tap caskroom/fonts && brew cask install font-iosevka` (May be outdated).
  * Customizable install using Homebrew: see [robertgzr/homebrew-tap](https://github.com/robertgzr/homebrew-tap).
* **Linux** : Copy the TTF files to your fonts directory → Run `sudo fc-cache`. 
  - Arch Linux users can install the font from the AUR [here](https://aur.archlinux.org/packages/ttf-iosevka) using an AUR wrapper or by doing it manually. [All variants](https://aur.archlinux.org/packages/?O=0&SeB=nd&K=ttf-iosevka&SB=n&SO=a&PP=50&do_Search=Go).
  - Void Linux users can install the font with `xbps-install font-iosevka`.
* **FreeBSD**: The font can be installed with `pkg install iosevka`.

## Weights, Variants and OpenType features

The typeface contains 9 weights (Thin to Heavy) alongside with both italic and oblique versions, with the same metrics as the regular one. 

![Weights sample](https://raw.githubusercontent.com/be5invis/Iosevka/master/images/weights.png)

All versions include the same ranges of characters: Latin letters, Greek letters (including Polytonic), some Cyrillic letters, IPA symbols and common punctuations and some symbols. You can check out the full list [here](http://be5invis.github.io/Iosevka/specimen.html).

![Languages Sample](https://raw.githubusercontent.com/be5invis/Iosevka/master/images/languages.png)

Iosevka supports accessing all letter variants using OpenType features.

### Ligations

![Ligations Sample](https://raw.githubusercontent.com/be5invis/Iosevka/master/images/ligations.png)

Iosevka’s default ligation set is assigned to `calt` feature, though not all of them are enabled by default.

Iosevka supports Language-Specific Ligations, which is the ligation set enabled only under certain languages. These ligation sets are assigned to custom feature tags, like `XHS0`.

## Building from Source

To build Iosevka you should:

1. Ensure that [`nodejs`](http://nodejs.org) (≥ 8.4), [`ttfautohint`](http://www.freetype.org/ttfautohint/), [`otfcc`](https://github.com/caryll/otfcc) (≥ 0.9.3).
2. Install necessary libs by `npm install`. If you’ve installed them, upgrade to the latest.
3. `npm run build -- contents:iosevka`.


You will find TTFs, as well as WOFF(2) web fonts and one Webfont CSS in the `dist/` directory.

## Build Your Own Style

Since version 2.0, Iosevka would no longer support building via `makefile`. To initialize a custom build, you need:

1. Create `private-build-plans.toml` file.

2. Add a build plan into `private-build-plans.toml`, following this format:

   ```toml
   [buildPlans.iosevka-custom]            # <iosevka-custom> is your plan name
   family = "Iosevka Custom"              # Font menu family name
   design = ["common styles"]             # Common styles
   upright = ["upright-only", "styles"]   # Upright-only styles
   italic = ["italic-only", "styles"]     # Italic-only styles
   oblique = ["oblique-only", "styles"]   # Oblique-only styles
   
   # Override default building weights
   # When buildPlans.<plan name>.weights is absent
   # All weights would built and mapped to default shape/CSS
   [buildPlans.iosevka-custom.weights.regular]
   shape = 400                            # Weight for glyph shapes
   menu  = 400                            # Weight for menu name
   css   = 400                            # Weight for WebFont CSS
   
   [buildPlans.iosevka-custom.weights.bold]
   shape = 700
   menu  = 700
   css   = 700
   
   # Override default building slant sets
   # Format: <upright|italic|oblique> = <"normal"|"italic"|"oblique">
   # When this section is absent, all slants would be built.
   [buildPlans.iosevka-custom.slants]
   upright = "normal"
   italic = "italic"
   oblique = "oblique"
   ```

3. Run `npm run build -- contents:<your plan name>` and the built fonts would be available in `dist/`. Aside from `contents:<plan>`, other options are:

   1. `contents:<plan>` : TTF (Hinted and Unhinted), WOFF(2) and Webfont CSS;
   2. `ttf:<plan>` : TTF;
   3. `ttf-unhinted:<plan>` : Unhinted TTF only;
   4. `woff:<plan>` : TTF and WOFF only;
   5. `woff2:<plan>` : TTF and WOFF2 only;

The current available styles for `design`/`upright`/`italic`/`oblique` options are:

* Styles for general shape:
  * `sans` : Sans serif (default).
  * `slab` : Slab serif.
* Styles related to ligations and spacing:
  - `term` : Disable ligations and exact monospace.
    - The font built will not contain ligatures.
    - All glyphs wider than one letter would be deleted.
    - In case of your OS or editor cannot handle ligatures correctly, you can disable ligations with it.
  - `termlig` : Similar to `term`, the font is exact monospace to make `fontconfig` happy, while ligations are still present.
  - `nolig` : Disable ligation only.
  - `type` : Make some symbols, like arrows (`→`) and mathematical operators full-width.
  - `stress-fw` : When included, full-width characters varying form `U+FF00` to `U+FFFF` will be boxed to present a clear distinguish between ASCII and Full-width.
* All registered `ss##` and `cv##` feature tags, including:
  * `ss01`~`ss10` : Predefined stylistic sets based on other Monospace fonts.
  * `cv01`~`cv53` : Standalone character variants.
* Styles for ligation sets, include:
  * `ligset-haskell`: Default ligation set would be assigned to Haskell.

![Family Matrix](https://raw.githubusercontent.com/be5invis/Iosevka/master/images/matrix.png)

## 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.
