= Quick use of a new font Fonts location on your computer =
Let's take a example, we want The first step is to use [https://declare the storage locations of the fonts.google.com/specimen/Noto+Serif Noto Serif]. The google website enable us you want ConTeXt to download a zip file with the 4 alternative variations (Regular 400, Regular 400 italic, Bold 700, Bold 700 italic)consider.
; #1Either way, ConTeXt will use fonts properly stored in its tree structure (for example, any fonts you would have downloaded from [https://www.fontsquirrel.com Fonts Squirrel] [https://fonts.google.com Google Fonts], or see [[Available Free Fonts]]). Store them is a dedicated folder:* '''TeX users create a "Noto-serif" new folder for each new font in the ConTeXt distribution <code>tex/texmf-fonts/fonts/</code>''', following [http://tug.org/tds/ TeX Directory Structure].:* unzip * it helps the algorithms to deal with the incredibly wide variety of fonts's variables and store the parameters.ttf file in ** People who handle a lot of fonts can be more structured by using <code>tex/texmf-fonts/Noto-seriffonts/truetype/vendor/fontfamily</code>.
But it it's very likely that you also want to use the '''fonts already available on your Operating System''':;1. Specify where ConTeXt should looked for fonts, by setting the '''OSFONTDIR''' environment variable.:* WINDOWS: <code>set OSFONTDIR=c:/windows/fonts/</code>:* MAC: <code>export OSFONTDIR=/Library/Fonts/;/System/Library/Fonts;$HOME/Library/Fonts</code>:* GNU/LINUX: <code>export OSFONTDIR=$HOME/.fonts;/usr/share/fonts</code>:* Add it to your .bashrc or shell equivalent to make the declaration permanent.; 2. Run ConTeXt to index the files:* update of the file database: <code>mtxrun --generate</code>:* update of the fonts database: <code>mtxrun --script font --reload</code>;3. Check by looking for the specific font you want to use next:* a very common example <code>mtxrun --script font --list --file -pattern=*helvetica*</code> Now, let's learn how to use them for typesetting. = Practical application #1 - Quick use of a new font = Let's take a example: we want to use [https://fonts.google.com/specimen/Noto+Serif Noto Serif].  If it is already installed on your computer, and you already updated the ConTeXt databases like shown previously, go directly to '''#2'''. It not, you have to download and store it first. Google website provides a zip file with the 4 alternative variations (Regular 400, Regular 400 italic, Bold 700, Bold 700 italic). ; #1. Store them is a dedicated folder [[#Fonts location on your computer|indexed by ConTeXt]]. :* for example, create a "Noto-serif" in the ConTeXt distribution <code>tex/texmf-fonts/fonts/</code>.:* unzip and store the .ttf file in <code>tex/texmf-fonts/fonts/Noto-serif/</code>.:* Regenerate ConTeXt databases:** the file database: <code>mtxrun --generate</code>:** the fonts database: <code>mtxrun --script font --reload</code> ; #2. Now you can check the ''fontname'' used to identify the fonts, :* and check the situation run <code>mtxrun --script font --list --file -pattern=*noto*</code>:. You should obtain something like
<texcode>familyname weight style width variant fontname filename subfont fontweight
</texcode>
; #3. Your are done! You can use the font anywhere in your input files with {{cmd|definedfont}}:* it's good to add <code>*default</code> to benefit from default features, like for example [http://www.pragma-ade.com/general/manuals/fonts-mkiv.pdf#&#91;169,{%22name%22:%22Fit%22}&#93; kerning].
<texcode>
\definedfont[filename:NotoSerif-BoldItalic notoserifbolditalic*default at 12pt12 pt]
The quick brown fox jumps over the lazy dog
</texcode>

= Practical application #2 - Use the different font variations =
 = Use of the different font variations = * It's not nice to have to write \definedfont[filename:YourSuperFontyoursuperfont-WeightStyle weightstyle*default at xxpt] each time you want to use a particular font.
* That why it's worth defining a '''typescript'''. It's just 3 steps, and less than 5 minutes. Then, you will be able to easily switch between fonts with {{cmd|tf}}, {{cmd|it}}, {{cmd|bf}}, {{cmd|bi}} (see [[Font_Switching#Font_styles_and_alternatives]]), and all the typesetting of your document will use a consistent set of fonts.
* [[Typescripts_examples| Many typescripts are ready ]] for use on usual free and commercial fonts, and obviously for the [[ConTeXt_distribution's_Fonts|ConTeXt distribution's Fonts]].

= Install and use your new typescript definition to use it anywhere =
You will probably want to use your new customized typescript definition across different documents, so you have to install them in the distribution. Here is the definition.
