+Once we have created our project, defined all the necessary metadata in the toml file, its time to publish our project. Let see the tools and steps we need to acheive this.
+We need to install the following tools
+  1. `build` : A tool to read the ['pyproject']toml file and build the package files
+     ```bash
+     pip install build
+     
+     python -m build
+     ```
+     This command creates a dist directory containing two files:
+      ```output
+      ```
+      A wheel file (e.g., my_minimal_package-0.0.1-py3-none-any.whl).
+
+      A source archive (e.g., my-minimal-package-0.0.1.tar.gz).
+
+  2. `twine` :  A tool for securely uploading packages to PyPI and TestPyPI.
+   ```bash
+   pip install build twine
+
+   twine upload --repository testpypi dist/*
+   ```
+  You'll be prompted to enter your TestPyPI username and password. It's recommended to use an API token instead of      your password. When prompted for your password, paste the token in.
+  
+  That's it! After the upload is successful, your package will be available on TestPyPI.
