-If multiple config files are specified, they are merged in order. Later files override earlier ones.
+**Priority Rules:**
+
+1. **CLI flags** (`-f`) have highest priority, processed left to right (rightmost wins)
+2. **Included files** (via `configFile` property) are processed with lower priority than their parent
+3. **Environment variable** (`SARIN_CONFIG_FILE`) has lowest priority
 
 **Example:**
 
 ```yaml
 # config2.yaml
 configFile: /config4.yaml
+url: http://from-config2.com
 ```
 
 ```sh
 SARIN_CONFIG_FILE=/config1.yaml sarin -f /config2.yaml -f https://example.com/config3.yaml

-In this example, all 4 config files are read and merged with the following priority:
+**Resolution order (lowest to highest priority):**
 
-```
+| Source                   | File         | Priority |
-config3.yaml > config2.yaml > config4.yaml > config1.yaml
+| ------------------------ | ------------ | -------- |
-```
+| ENV (SARIN_CONFIG_FILE)  | config1.yaml | Lowest   |
+| Included by config2.yaml | config4.yaml | ↑        |
+| CLI -f (first)           | config2.yaml | ↑        |
+| CLI -f (second)          | config3.yaml | Highest  |
+
+**Why this order?**
+
+- `config1.yaml` comes from ENV → lowest priority
+- `config2.yaml` comes from CLI → higher than ENV
+- `config4.yaml` is included BY `config2.yaml` → inherits position below its parent
+- `config3.yaml` comes from CLI after `config2.yaml` → highest priority
+
+If all four files define `url`, the value from `config3.yaml` wins.
