 Integration of `impl` tool to generate method stubs for interfaces.
 
 Usage ~

 1. Automatically implement an interface for a struct:
-   - Place your cursor on the struct where you want to implement the interface.
-   - Run `:GoImpl io.Reader`
-   - This will automatically determine the receiver and implement the `io.Reader` interface.
+ - Place your cursor on the struct where you want to implement the interface.
+ - Run `:GoImpl io.Reader`
+ - This will automatically determine the receiver and implement the `io.Reader` interface.
 
 2. Specify a custom receiver:
-   - Place your cursor on the struct
-   - Run `:GoImpl w io.Writer`, where:
-     - `w` is the receiver.
-     - `io.Writer` is the interface to implement.
+ - Place your cursor on the struct
+ - Run `:GoImpl w io.Writer`, where:
+  - `w` is the receiver.
+  - `io.Writer` is the interface to implement.
 
 3. Explicitly specify the receiver, struct, and interface:
-   - No need to place the cursor on the struct if all arguments are provided.
-   - Run `:GoImpl r RequestReader io.Reader`, where:
-     - `r` is the receiver.
-     - `RequestReader` is the struct.
