-How to update Matrix?
-=====================
-
-## 1. Build the new containers
-
-Often, I update Riot Web and Synapse at the same time.
-
-
-* Open `app/docker-compose.yml` and locate `riot` (the Element Web service) and `synapse` (the Matrix Synapse server). There are two things you need to do for each service:
-
-    * Set the `VERSION` argument to the target service version (e.g. `1.26.0` for Synapse). This argument is then used to template the Dockerfile. 
-
-    The `VERSION` value should match a github release, the link to the corresponding release page is put as a comment next to the variable in the compose file;
-
-    * Tag the image with a new incremented version tag. For example: `superboum/amd64_riotweb:v17` will become `superboum/amd64_riotweb:v18`.
-
-    We use the docker hub to store our images. So, if you are not `superboum` you must change the name with your own handle, eg. `john/amd64_riotweb:v18`. This requires that you registered an account (named `john`) on https://hub.docker.com.
-
-
-So, from now we expect you have:
-
-* changed the `VERSION` value and `image` name/tag of `riot`
-* changed the `VERSION` value and `image` name/tag of `synapse`
-
-From the `/app` folder, you can now simply build and push the new images:
-
-```bash
-docker-compose build riot synapse
-```
-
-And then send them to the docker hub:
-
-```
-docker-compose push riot synapse
-```
-
-Don't forget to commit and push your changes before doing anything else!
-
-## 2. Deploy the new containers
-
-Now, we will edit the deployment file `app/im/deploy/im.hcl`.
-
-Find where the image is defined in the file, for example Element-web will look like that:
-
-
-```hcl
-  group "riotweb" {
-    count = 1
-
-    task "server" {
-      driver = "docker"
-      config {
-        image = "superboum/amd64_riotweb:v17"
-        port_map {
-          web_port = 8043
-        }
-```
-
-And replace the `image =` entry with its new version created above.
-Do the same thing for the `synapse` service.
-
-Now, you need a way to access the cluster to deploy this file.
-To do this, you must bind nomad on your machine through a SSH tunnel.
-Check the end of [the parent `README.md`](../README.md) to do it.
-If you have access to the Nomad web UI when entering http://127.0.0.1:4646
-you are ready to go.
-
-You must have installed the Nomad command line tool on your machine (also explained in [the parent `README.md`](../README.md)).
-
-Now, on your machine and from the `app/im/deploy` folder, you must be able to run:
-
-```
-nomad plan im.hcl
-```
-
-Check that the proposed diff corresponds to what you have in mind.
-If it seems OK, just copy paste the `nomad job run ... im.hcl` command proposed as part of the output of the `nomad plan` command.
-
-From now, it will take around ~2 minutes to deploy the new images.
-You can follow the deployment from the Nomad UI.
-Bear in mind that, once the deployment is done on Nomad, you may still need to wait some minutes that Traefik refreshes its configuration.
-
-If everythings worked as intended, you can commit and push your deployment file.
-
-If something went wrong, you must rollback your deployment.
-
-  1. First, find a working deployment with [nomad job history](https://www.nomadproject.io/docs/commands/job/history)
-  2. Revert to this deployment with [nomad job revert](https://www.nomadproject.io/docs/commands/job/revert)
-
-Now, if the deployment failed, you should probably investigate what went wrong offline.
-I built a test stack with docker-compose in `app/<service>/integration` that should help you out (for now, test suites are only written for plume and jitsi).
