-# yaml-patch
+# yaml-patch
+
+Apply patches to a yaml string, keeping most of the formatting and comments.
+
+Some formatting is not kept due to underlying yaml library limitations:
+  - Indentation will be forced to two spaces
+  - Spacing before sequence dashes will be forced to two spaces
+  - Empty lines at the start of the string will be removed
+
+## As a command line tool
+
+You can pass any number of patches to be applied, they use the following syntax options:
+
+### Patch a single value:
+`<field>.<subfield>=<value>`
+
+Example:
+```bash
+yaml-patch -f test.yml  'spec.replicas=2'
+```
+
+### Patch a value inside a single list item:
+`<field>.[<position]>.<subfield>=<value>`
+
+Example:
+```bash
+yaml-patch -f test.yml  'spec.template.containers.[0].image="mycontainer:latest"'
+```
+
+### Patch a value inside all list items:
+`<field>.[].<subfield>=<value>`
+
+Example:
+```bash
+yaml-patch -f test.yml 'spec.template.containers.[].image="mycontainer:latest"'
+```
+
+## As a Python library
+
+To use `yaml-patch` as a library just import the function and pass patches as dictionary entries.
+
+Example:
+
+```python
+from yaml_patch import patch
+from textwrap import dedent
+
+def override_list_all_values():
+    source_yaml = dedent(
+        """\
+        some_list:
+          - alice
+          - bob
+        """
+    )
+    patches = {"some_list.[]": "charlie"}
+    expected_yaml = dedent(
+        """\
+        some_list:
+          - charlie
+          - charlie
+        """
+    )
+    assert patch(source_yaml, patches) == expected_yaml
+```
