 ## Installation
 
-Go to the [releases page](https://github.com/cortex-command-community/Cortex-Command-Legacy-Mod-Converter/releases).
+See the [releases page](https://github.com/cortex-command-community/Cortex-Command-Legacy-Mod-Converter/releases).
 
 ## Conversion rules
 
 This line from `rules/ini_copy_of_rules.json`:
 
 `"Round M16": "Round Ronin M16",`
 
-states that whenever `Round M16` is encountered by the converter, it should change it to `Round Ronin M16`.
+states that whenever `CopyOf = Round M16` is encountered by the converter, it should change it to `CopyOf = Round Ronin M16`.
 
 This means you can make the converter "smarter" by adding more rules to the JSON files in the `rules/` directory.
 
+Look at the names of the JSON files (or how they're used in `src/main.zig`) to figure out how the converter uses each JSON file.
+
+Note that the converter will ignore any extra JSON files you put in the `rules/` directory.
