+## Usage
+
+After installation, you can use the `json-to-sql` command to convert a JSON file to SQL. The basic usage is as follows:
+
+```bash
+json-to-sql <file> [table] [--normalize] [dest]
+```
+
+- `file`: The JSON file to convert.
+- `table`: (Optional) The table name for the SQL file. If not provided, the filename will be used.
+- `--normalize`: (Optional) Normalize the JSON data.
+- `dest`: (Optional) Destination path for the SQL file. If not provided, the current directory will be used.
+
+### Examples
+
+Convert a JSON file to SQL with default settings:
+
+```bash
+json-to-sql data.json
+```
+
+Convert a JSON file to SQL with a specified table name:
+
+```bash
+json-to-sql data.json my_table
+```
+
+Convert a JSON file to SQL with normalization:
+
+```bash
+json-to-sql data.json --normalize
+```
+
+Convert a JSON file to SQL and save the output to a specific directory:
+
+```bash
+json-to-sql data.json my_table --normalize /path/to/output
+```
+
 ## Motivation
 
 The motivation behind this project was to learn functional programming language and this was the best way for me. I chose to implement this project idea as I needed to get some base knowledge around parsers and improve the current online json2sql parsers we have on the web. I won't recommend this to use for complex jsons but for simple jsons, this should work fine.
