 The data/ directory contains a prettified JSON file and a minified JSON file for each Wikimedia project. The all.json and all.min.json files include all the Wikimedia wikis, including not only the projects that have their own JSON files but also multilingual and special wikis.
 
 To update the JSON files, run `make`.

+## Running on toolforge
+To run on toolforge log into the tool accounnt:
+```
+ssh myuser@login.toolforge.org
+myuser@tools-sgebastion-10:$ become wmf-sitematrix
+wmf-sitematrix@tools-sgebastion-10:$
+```
+
+Start a build to pick up the new code
+```
+wmf-sitematrix@tools-sgebastion-10:$ toolforge build start https://github.com/osmlab/wmf-sitematrix
+... takes a minute
+```
+
+
+Start/restart the webservice mounting the NFS:
+```
+wmf-sitematrix@tools-sgebastion-10:$ toolforge webservice buildservice --mount=all restart
+```
+
+And create the job if it's not there to update `public_html/data/*json`:
+```
+wmf-sitematrix@tools-sgebastion-10:$ toolforge jobs run \
+    --schedule '0 0 */15 * *' \
+    --filelog \
+    --mount=all \
+    --image tool-wmf-sitematrix/tool-wmf-sitematrix:latest \
+    --command 'update' \
+    cron-tools.wmf-sitematrix-1
+```
+
+Or restart it if it exists and you want to run it right away:
+```
+wmf-sitematrix@tools-sgebastion-10:$ toolforge jobs restart cron-tools.wmf-sitematrix-1
+```
+
+Otherwise the next run will pull the new code.
