+# 🎛 Config File
+
+## Path
+
+By default autorestic searches for a `.autorestic.yml` file in the current directory and your home folder.
+
+- `./.autorestic.yml`
+- `~/.autorestic.yml`
+
+You can also specify a custom file with the `-c path/to/some/config.yml`
+
+> **⚠️ WARNING ⚠️**
+>
+> 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!
+
+## Example configuration
+
+```yaml | .autorestic.yml
+version: 2
+
+locations:
+  home:
+    from: /home/me
+    to: remote
+
+  important:
+    from: /path/to/important/stuff
+    to:
+      - remote
+      - hdd
+
+backends:
+  remote:
+    type: b2
+    path: 'myBucket:backup/home'
+    env:
+      B2_ACCOUNT_ID: account_id
+      B2_ACCOUNT_KEY: account_key
+
+  hdd:
+    type: local
+    path: /mnt/my_external_storage
+```
+
+## Aliases
+
+A handy tool for more advanced configurations is to use yaml aliases.
+These must be specified under the global `extras` key in the `.autorestic.yml` config file.
+Aliases allow to reuse snippets of config throughout the same file.
+
+The following example shows how the locations `a` and `b` share the same hooks and forget policies.
+
+```yaml | .autorestic.yml
+version: 2
+
+extras:
+  hooks: &foo
+    before:
+      - echo "Hello"
+    after:
+      - echo "kthxbye"
+  policies: &bar
+    keep-daily: 14
+    keep-weekly: 52
+
+backends:
+  # ...
+locations:
+  a:
+    from: /data/a
+    to: some
+    hooks:
+      <<: *foo
+    options:
+      forget:
+        <<: *bar
+  b:
+    from: data/b
+    to: some
+    hooks:
+      <<: *foo
+    options:
+      forget:
+        <<: *bar
+```
