+[Poetry](https://python-poetry.org/) is Python package manager. It is used to manage dependencies and virtual
+environments for Presidio services.
+Follow these steps when starting to work on a Presidio service with poetry:
 
-1. Install Pipenv
+1. Install poetry
 
     - Using Pip
 
         ```sh
-        pip install --user pipenv
+        pip install poetry
         ```
 
     - Using Homebrew (in MacOS)
 
         ```
-        brew install pipenv
+        brew install poetry
         ```
 
-    Additional installation instructions for Pipenv: <https://pipenv.readthedocs.io/en/latest/install/#installing-pipenv>
+    Additional installation instructions for poetry: <https://python-poetry.org/docs/#installation>
 
-2. Have Pipenv create a virtualenv for the project and install all requirements in the Pipfile,
+2. Have poetry create a virtualenv for the project and install all requirements in the pyproject.toml,
     including dev requirements.
 
     For example, in the `presidio-analyzer` folder, run:
 
     ```
-    pipenv install --dev --skip-lock
+    poetry install --all-extras
     ```
 
 3. Run all tests:
 
     ```
-    pipenv run pytest
+    poetry run pytest
     ```
 
 4. To run arbitrary scripts within the virtual env, start the command with
-    `pipenv run`. For example:
-    1. `pipenv run ruff check`
-    2. `pipenv run pip freeze`
-    3. `pipenv run python -m spacy download en_core_web_lg`
+    `poetry run`. For example:
+    1. `poetry run ruff check`
+    2. `poetry run pip freeze`
+    3. `poetry run python -m spacy download en_core_web_lg`
 
     Command 3 downloads the default spacy model needed for Presidio Analyzer.`
 
-#### Alternatively, activate the virtual environment and use the commands by starting a pipenv shell
-
-1. Start shell:
-
-    ```
-    pipenv shell
-    ```
-
-2. Run commands in the shell
-
-    ```
-    pytest
-    pip freeze
-    ```
+#### Alternatively, activate the virtual environment and use the commands using [this method](https://python-poetry.org/docs/basic-usage/#activating-the-virtual-environment).
