+

+1. Fork the [repository](https://github.com/fetchai/uAgents.git).
+2. Clone your fork of the repository:
+    <!-- markdown-link-check-enable -->
+
+   ``` shell
+   git clone https://github.com/fetchai/uAgents.git
+   ```
+
+3. Define an `upstream` remote pointing back to the main uAgents repository:
+
+   ``` shell
+   git remote add upstream https://github.com/fetchai/uAgents.git
+   ```
+
+## <a name="setup"></a> Setting up a New Development Environment
+
+The easiest way to get set up for development is to install Python (`3.9` to `3.12`) and [poetry](https://pypi.org/project/poetry/), and then run the following from the top-level project directory:
+
+```bash
+  cd python
+  poetry install
+  poetry shell
+  pre-commit install
+```
+
+## <a name="dev"></a>Development
+
+When developing for `uAgents` make sure to have the poetry shell active. This ensures that linting and formatting will automatically be checked during `git commit`.
+
+We are using [Ruff](https://github.com/astral-sh/ruff) with added rules for formatting and linting.
+Please consider adding `ruff` to your IDE to speed up the development process and ensure you only commit clean code.
+
+Alternately you can invoke ruff by typing the following from within the `./python` folder
+
+```bash
+  ruff check --fix && ruff format
+```
+
+## <a name="test"></a>Testing
+
+To run tests use the following command:
+
+```bash
+  pytest
+```
