Make sure you have https://nixos.org/download.html[Nix] installed.
You may also want to xref:../installation/binary-cache.adoc[configure the Spectrum
binary cache], to avoid having to wait for dependencies to compile on
your local system.

. Get a copy of the Spectrum source code:
+
[source,shell]
----
git clone https://spectrum-os.org/git/spectrum
----
. Enter the documentation directory:
+
[source,shell]
----
cd spectrum/Documentation
----
. Enter the development environment:
+
[source,shell]
----
nix-shell -I nixpkgs=https://spectrum-os.org/git/nixpkgs/snapshot/nixpkgs-rootfs.tar.gz
----
. In the development shell, do an initial build of the documentation
site:
+
[source,shell]
----
scripts/build.sh
----
. Run a development server for previewing changes locally:
+
[source,shell]
----
jekyll serve
----
+
This will serve a local copy of the documentation at http://localhost:4000/.
+
IMPORTANT: Jekyll does not handle rendering of the draw.io diagrams. If you
modify any of those, or add new ones, run `scripts/build.sh` again to do a full
rebuild of the site.

After making changes to the documentation, see how to
xref:first-patch.adoc[send your patch] and submit the changes for review.
