+## Install Debian
+
+We recommend Debian Bullseye
+
+## Install Docker CE from docker.io
+
+Do not use the docker engine shipped by Debian
+
+Doc:
+
+  - https://docs.docker.com/engine/install/debian/
+  - https://docs.docker.com/compose/install/
+
+On a fresh install, as root:
+
+```bash
+apt-get remove -y docker docker-engine docker.io containerd runc
+apt-get update
+apt-get install apt-transport-https ca-certificates curl gnupg lsb-release
+curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
+ echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian $(lsb_release -cs) stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null
+apt-get update
+apt-get install -y docker-ce docker-ce-cli containerd.io
+
+curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
+chmod +x /usr/local/bin/docker-compose
+```
+
+## Prepare the runner
+
+Nix folder must be populated before launching any build.
+
+```bash
+docker run --rm -it -v /var/lib/drone/nix:/mnt nixpkgs/nix:nixos-21.05 cp -r /nix/{store,var} /mnt/
+```
+
+This folder will grow over time and might need to be garbage collected.
+As a rule of thumb, after running a full release of Garage, this folder will require 10GB.
+Consider provisioning it with at least 20GB.
+
+## Launch the runner
+
+Because we use a shared nix folder, we set the number of concurrent builds to 1.
+For more details and customizations, see `docker-compose.yml`.
+
+```bash
+DRONE_NAME=lheureduthe DRONE_OWNER=quentin DRONE_SECRET=xxx docker-compose up -d
+```
+
+That's all folks.
+
+## Check if a given job is built by your runner
+
+```bash
+export URL=https://drone.deuxfleurs.fr
+export REPO=Deuxfleurs/garage
+export BUILD=1312
+curl ${URL}/api/repos/${REPO}/builds/${BUILD} \
+  | jq -c '[.stages[] | { name: .name, machine: .machine }]'
+```
+
+It will give you the following result:
+
+```json
+[{"name":"default","machine":"1686a"},{"name":"release-linux-x86_64","machine":"vimaire"},{"name":"release-linux-i686","machine":"carcajou"},{"name":"release-linux-aarch64","machine":"caribou"},{"name":"release-linux-armv6l","machine":"cariacou"},{"name":"refresh-release-page","machine":null}]
+```
+
+## Random note
+
+This setup is done mainly to allow nix builds with some cache.
+To use the cache in Drone, you must set your repository as trusted.
+The command line tool does not work (it says it successfully set your repository as trusted but it did nothing):
+the only way to set your repository as trusted is to connect on the DB and set the `repo_trusted` field of your repo to true.
