+(These are notes for the maintainer)
+
+- To update "capacitor-android", copy the 'android'-directory from "(mapcomplete repo)/node_modules/@capacitor/android" into the adroid repo root
+    The path should be linked in capacitor.settings.gradle
+
+- In the `fdroiddata`-repostiroy, open `metadata/org.mapcomplete.yml`
+- Update the version number to match the MC  release
+- Bump the `CurrentVersionCode` with one
+
+Then, test the build (instructions adapted from [FDroids quick start guide](https://f-droid.org/en/docs/Submitting_to_F-Droid_Quick_Start_Guide/)):
+- Go to the `fdroidserver` rep in a terminal
+- Start the container with:
+```
+sudo docker run --rm -itu vagrant --entrypoint /bin/bash \
+  -v ~/fdroiddata:/build:z \
+  -v ~/fdroidserver:/home/vagrant/fdroidserver:Z \
+  registry.gitlab.com/fdroid/fdroidserver:buildserver
+```
+
+In the container, run:
+
+```
+. /etc/profile
+export PATH="$fdroidserver:$PATH" PYTHONPATH="$fdroidserver"
+export JAVA_HOME=$(java -XshowSettings:properties -version 2>&1 > /dev/null | grep 'java.home' | awk -F'=' '{print $2}' | tr -d ' ')
+cd /build
+fdroid readmeta
+fdroid rewritemeta org.mapcomplete
