README.md: expand the "Build Chatty" and add the "Install Chatty" sections
Currently, README.md has the following "Build Chatty" section:
meson build
ninja -C build
But there aren't any instructions for the install prefix, which are essential if a user would like to replace his phone distro's outdated Chatty with your git master version. Also, there is no "Install Chatty" section.
It seems I don't have the permissions at https://source.puri.sm/ to fork a project to make a pull request, but the parts of my instructions can be copied from the end of this ticket: #608 (closed)
For example:
### Build Chatty
git clone https://source.puri.sm/Librem5/chatty
cd ./chatty/
meson build -Dprefix=/usr
ninja -C build
cd build
ninja
### Install Chatty
pkill chatty
sudo ninja install
