+# Usage
+```
+usage: converter.py [-h] input_file output_file
+
+Converts ninja files to ShadowDash manifest files.
+
+positional arguments:
+  input_file   Path to the input file to process
+  output_file  Path to the output file
+
+options:
+  -h, --help   show this help message and exit
+```
+
+You can call it using the following command:
+```bash
+python3 converter.py input_file output_file
+```
+
+# Prerequisites
+- Python 3.6 or higher
+
+# Test
+
+To test the program we can use the files in the `docs` folder. The following command will convert the `build.ninja` file to a `build.ninja.cc` file:
+```bash
+python3 converter.py ../docs/build.ninja build.ninja.cc
+```
+Aside from formatting, the file `build.ninja.cc` should be identical to the `build.ninja.cc` file in the docs directory.
+
+# Implementation
+
+The program is implemeted to match the languages developed by the `ninja` build system and Team 4 `new-language` subteam.
