-Version `v0.0.26` is verified to work with Haskell indexer.
+Version `v0.0.30` is the latest version that includes the web UI.  If you want a
+newer Kythe than this, you'll need to build from source.
 
 If you want to install Kythe in a different location to `/opt/kythe` then you
 should also set `KYTHE_DIR` to the location of the installation.
 
+### Building From Source
+
+Clone Kythe from [its GitHub repo](https://github.com/google/kythe/releases) and
+follow the [Getting Started guide](https://kythe.io/getting-started/) to build
+and install it into `/opt/kythe`.  Then, from within the Kythe clone, build the
+web frontend and copy its files into their rightful place:
+
+```
+bazel build //kythe/web/ui
+mkdir -p /opt/kythe/web/ui
+cp -r bazel-bin/kythe/web/ui/resources/public/* /opt/kythe/web/ui
+cp -r kythe/web/ui/resources/public/* /opt/kythe/web/ui
+chmod -R 755 /opt/kythe/web/ui
