|
### On the TeX distribution
|
||
|
|
|
||
|
|
- If there are no special reasons, you should always install Fira Math via the package manager:
|
||
|
|
|
||
|
|
- TeX Live: run `tlmgr install firamath`
|
||
|
|
- MiKTeX: run `mpm --admin --install=firamath`
|
||
|
|
|
||
|
|
Both distributions have GUI interfaces, you may enjoy them as well.
|
||
|
|
|
||
|
|
- **[NOT RECOMMENDED]** Download `firamath.tds.zip` from [CTAN](https://ctan.org/pkg/firamath) or [GitHub release page](https://github.com/firamath/firamath/releases), extract it in the root of one of your TDS trees, then run `mktexlsr` and `fc-cache` to update the filename database and font cache.
|
||
|
|
|
||
|
|

|
### Microsoft Word
|
||
|
|
|
||
|
|
1. Create a new equation. Then select the little *additional settings* corner.
|
||
|
|
1. In the menu, change the *Default font* to Fira Math.
|
||
|
|
1. In order for the changes to take effect, you will have to create a new equation environment (the current one will not be changed).
|
||
|
|
1. To change the font in existing equations, select the equation text and select an OpenType math-enabled font (such as Fira Math).

## Building from source
|
||
|
|
|
||
|
|
To build Fira Math, you may
|
||
|
|
|
||
|
|
```sh
|
||
|
|
python -m pip install -U pip
|
||
|
|
pip install -r requirements.txt
|
||
|
|
patch $(python -c "import os, glyphsLib; print(os.path.join(glyphsLib.__path__[0], 'builder', 'axes.py'))") scripts/axes.py.diff
|
||
|
|
python scripts/build.py
|
||
|
|
```
|
||
|
|
|
||
|
|
Note that Python 3.9+ is required. Since we are using [the dev version of glyphsLib](https://github.com/googlefonts/glyphsLib/pull/652), it's better to use a Python virtual environment.
|
||
|
|
|
||
|
|
To edit the source files, [Glyphs 3](https://glyphsapp.com/) is required.
|
||
|
|
|
||
|
|
