-There is not yet any source code for Subplot. There was a prototype
-before the name changed, see <https://fable.liw.fi/>.
+## Source code
 
-The git repository containing the source of this website is at
-<http://git.liw.fi/subplot.liw.fi>.
+Subplot source code is distributed via the git version control system.
+There are two repositories, which are intended to be identical:
+
+* GitLab: <https://gitlab.com/larswirzenius/subplot>
+* git.liw.fi: <http://git.liw.fi/subplot/>
+
+Use either according to preference.
+
+## Build and install from source
+
+Subplot is written in the Rust language, and you need the Rust
+toolchain and cargo installed. If you have that installed and
+configured, you can build and install Subplot from source as follows:
+
+~~~sh
+git clone https://gitlab.com/larswirzenius/subplot
+cd subplot
+cargo build
+cargo install --path=.
+~~~
+
+## Debian
+
+There are Debian packages built by CI from every commit. They work on
+Debian 10 (buster) ans later. Add the following to
+`/etc/apt/sources.list.d/subplot.list`:
+
+~~~
+deb http://ci-prod-controller.vm.liw.fi/debian unstable-ci main
+~~~
+
+Then save the following PGP public key to
+`/etc/apt/trusted.gpg.d/subplot.asc`:

+
+After that run the following commands to install Subplot:
+
+~~~sh
+apt update
+apt install subplot
+~~~
+
+## Other systems
+
+The Subplot developers all use Debian on the 64-bit Intel
+architecture, and don't provide installation packages for other kinds
+of systems (other architectures, other operating systems). If you'd
+like to help with that, it would be very much welcome!
