+
+An Android Studio template has been added to the project to help creating all files needed when adding a new screen to the application. Fragment, ViewModel, Activity, etc.

+To install the template (to be done only once):
+- Go to folder `./tools/template`.

+- Restart Android Studio.
+
+To create a new screen:
+- First create a new package in your code.
+- Then right click on the package, and select `New/New Vector/RiotX Feature`.
+- Follow the Wizard, especially replace `Main` by something more relevant to your feature.
+- Click on `Finish`.
+- Remainning steps are described as TODO in the generated files, or will be pointed out by the compilator, or at runtime :)

+Note that if the templates are modified, the only things to do is to restart Android Studio for the change to take effect.

+# Integration tests
+
+Integration tests are useful to ensure that the code works well for any use cases.
+
+They can also be used as sample on how to use the Matrix SDK.
+
+In a ideal world, every API of the SDK should be covered by integration tests. For the moment, we have test mainly for the Crypto part, which is the tricky part. But it covers quite a lot of features: accounts creation, login to existing account, send encrypted messages, keys backup, verification, etc.
+
+The Matrix SDK is able to open multiple sessions, for the same user, of for different users. This way we can test communication between several sessions on a single device.
+
+## Pre requirements
+
+Integration tests need a homeserver running on localhost.
+
+The documentation describes what we do to have one, using [Synapse](https://github.com/matrix-org/synapse/), which is the Matrix reference homeserver.
+
+## Install and run Synapse
+
+Steps:
+
+- Install virtualenv
+
+```bash
+python3 -m pip install virtualenv
+```
+
+- Clone Synapse repository
+
+```bash
+git clone -b develop https://github.com/matrix-org/synapse.git
+```
+or
+```bash
+git clone -b develop git@github.com:matrix-org/synapse.git
+```
+
+You should have the develop branch cloned by default.
+
+- Run synapse, from the Synapse folder you just cloned
+
+```bash
+virtualenv -p python3 env
+source env/bin/activate
+pip install -e .
+demo/start.sh --no-rate-limit
+```
+
+Alternatively, to install the latest Synapse release package (and not a cloned branch) you can run the following instead of `pip install -e .`:
+
+```bash
+pip install matrix-synapse
+```
+
+You should now have 3 running federated Synapse instances 🎉, at http://127.0.0.1:8080/, http://127.0.0.1:8081/ and  http://127.0.0.1:8082/, which should display a "It Works! Synapse is running" message.
+
+## Run the test
+
+It's recommended to run tests using an Android Emulator and not a real device. First reason for that is that the tests will use http://10.0.2.2:8080 to connect to Synapse, which run locally on your machine.
+
+You can run all the tests in the `androidTest` folders.
+
+## Stop Synapse
+
+To stop Synapse, you can run the following commands:
+
+```bash
+./demo/stop.sh
+```
+
+And you can deactivate the virtualenv:
+
+```bash
+deactivate
+```
+
+## Troubleshoot
+
+You'll need python3 to be able to run synapse
+
+### Android Emulator does cannot reach the homeserver
+
+Try on the Emulator browser to open "http://10.0.2.2:8080". You should see the "Synapse is running" message.
+
+### virtualenv command fails
+
+You can try using
+```bash
+python3 -m venv env
+```
+or
+```bash
+python3 -m virtualenv env
+```
+instead of
+```bash
+virtualenv -p python3 env
+```
