 ## 🚀 Quickstart
 
+##### ⚠️ Note ⚠️
+
+Note that the data is automatically encrypted on the server. The key will be generated and added to your config file. Every backend will have a separate key. **You should keep a copy of the keys or config file somewhere in case your server dies**. Otherwise DATA IS LOST!
+
+Also, currently comments in the config file will be deleted, due how the yaml parsing library works. I will fix this soon :)

 ### Setup
 
 First we need to configure our locations and backends. Simply create a `.autorestic.yml` either in your home directory of in the folder from which you will execute `autorestic`.

+#### 🐳 Docker volumes
+
+Since version 0.13 autorestic supports docker volumes directly, without needing them to be mounted to the host filesystem.
+
+Let see an example.
+
+###### docker-compose.yml
+
+```yaml
+version: '3.7'
+
+volumes:
+  data:
+    name: my-data
+
+services:
+  api:
+    image: alpine
+    volumes:
+      - data:/foo/bar
+```
+
+###### .autorestic.yml
+
+```yaml
+locations:
+  hello:
+    from: 'volume:my-data'
+    to:
+      - remote
+    options:
+      forget:
+        keep-last: 2
+
+backends:
+  remote:
+    ...
+```
+
+Now you can backup and restore as always.
+
+```sh
+autorestic -l hello backup
+```
+
+```sh
+autorestic -l hello restore
+```
+
+If the volume does not exist on restore, autorestic will create it for you and then fill it with the data.
+
+### Limitations
+
+Unfortunately there are some limitations when backing up directly from a docker volume without mounting the volume to the host. If you are curious or have ideas how to improve this, please [read more here](https://github.com/cupcakearmy/autorestic/issues/4#issuecomment-568771951). Any help is welcomed 🙂
+
+1. Incremental updates are not possible right now due to how the current docker mounting works.
+2. Exclude patterns and files also do not work as restic only sees a compressed tarball as source and not the actual data.

+## ❓ QA
+
+### My config file was moved?
+
+This happens when autorestic needs to write to the config file. This happend e.g. when we are generating a key for you.
+Unforunately during this process formatting and comments are lost. That is why autorestic will place a copy of your old config next to the one we are writing to.
