+#### Examples
+
+1. String
+
+   The following could be interpreted as either a string or an int:
+
+   ```shell
+   $ cat example.yaml
+   num: #yampl {{ .num }}
+   $ yampl example.yaml -v num=2009
+   num: 2009 #yampl {{ .num }}
+   ```
+
+   If this field must be a string, you could add the `str` tag:
+
+   ```shell
+   $ cat example.yaml
+   num: #yampl:str {{ .num }}
+   $ yampl example.yaml -v num=2009
+   num: "2009" #yampl:str {{ .num }}
+   ```
+
+2. Sequence
+
+   ```shell
+   $ cat example.yaml
+   seq: #yampl:seq {{ .seq }}
+   $ yampl example.yaml -v seq='[a, b, c]'
+   seq: #yampl {{ .seq }}
+     - a
+     - b
+     - c
+   ```
+
+3. Map
+
+   ```shell
+   $ cat example.yaml
+   map: #yampl:map {{ .map }}
+   $ yampl example.yaml -v map='{message: hello world}'
+   map: #yampl {{ .map }}
+     message: hello world
+   ```
