# Building
Talkatu uses [meson](https://mesonbuild.com) as it's build system.
Meson requires you to build in a directory other than the source directory.
To compile you can use the following commands:
```
meson build
cd build
```
To test Talkatu without installing, you can run the following command from the
build directory.
```
meson devenv talkatu-demo
```
To install you can use `ninja install` from the build directory.
