 # FritzAB2Matrix
 
-A script that reads out the answering machine of a FritzBox in the LAN and posts the messages into an encrypted private chat of the matrix network.
-
+__FritzAB2Matrix__ reads out the answering machine (_TAM_) of a _Fritz!Box_ in your LAN and posts the messages into a private chat in the __matrix__ network. While you could let your _Fritz!Box_ send the messages by mail - unencrypted of course - the matrix chat is __e2e encrypted__. Which kindly acknowledges the privacy of any caller that leaves a message for you.
 
 Uses the python based cmd-line-tool [matrix-commander](https://github.com/8go/matrix-commander) so the matrix-commander.py in this repo is just a copy of that file to ease testing.
+
+## Installation
+If you like to test this repository you are recommended to use one of the following two options.
+### Necessary preparations for both cases
+ * Create a new user (e.g. "fritzab") in your _Fritz!Box_. **Don't use your default admin account!**
+   * This user needs only the privileges regarding voice messages and to read from box's storage.
+   * As you only need to access the _FRITZ/voicebox/rec/_ path you should remove the right to read and write everything and add only this path and only with reading privilege.
+ * You have to activate __Call Monitoring__ on your _Fritz!Box_ by using one of the connected phones and call `#96*5*`.
+   * Call monitoring watches the box and the __FritzAB2Matrix__ is triggered every time a call disconnects.
+   * If you cannot activate Call Monitoring the only way to use __FritzAB2MAtrix__  will be to have a cron job call it regularly. 
+
+### virtualenv
+ * Create a new folder wherever you like in your home directory.
+   * Make it a virtual environment by `python3 -m venv <new folder>` and `source <new folder>/bin/activate`.
+   * `cd <new folder>`
+ * Clone the repo.
+ * Inside the repo run `pip install --update pip && pip install -r requirements.txt`
+ + Create an `.env` file with your favourite editor:
+ ```
+FRITZ_USERNAME="fritzab"
+FRITZ_PASSWORD="SomeRand0mPa55word"
+FRITZ_IP="192.168.178.1" 
+FRITZ_TMP="/tmp"
+
+ ```
+    * Adjust it according to your data.
+ * For matrix-commander.py to work you need to run it manually the first time by `python3 matrix-commander` and follow the emerging dialog by putting in your matrix account data.
+ * After all that you can finally run `./fritzab2matrix.py` and your TAM messages should be posted in the chosen matrix chat.
+### Docker
+Provided you have docker and docker-compose installed on your system:
+ * Clone the repo and cd into it.
+ * Create the above mentioned `.env` file.
+ * Run `docker-compose -f docker/docker-compose.yml build` and watch docker work some minutes.
+ * After that slightly edit the `docker-compose.yml`
+   * and add
+   ```
+   volumes:
+      - ../.:/app
+	  ```
+   * so that your repo is used as volume for the `/app` folder. So everything you change in the repo's folder will affect the docker container.
+ * For __matrix-commander.py__ to work you need to run it manually the first time by `python3 matrix-commander` and follow the emerging dialog by putting in your matrix account data.
+   * With docker that means that you need to open an _interactive shell_ in the running container (`docker-compose -f docker/docker-compose.yml exec app /bin/bash` and run this command there.
+   * Follow the appearing dialog and input your matrix account data.
+ * After all that the running docker container should watch your box and your TAM messages should be posted in the chosen matrix chat.
