 The scripts in this directory are used to generate the Evergreen configuration
 files stored in `.evergreen/generated_configs/`.
 
-The easiest way to execute these scripts is using the Poetry to install the
-dependencies and then run the scripts.
+The easiest way to execute these scripts is to use [uv](https://docs.astral.sh/uv/) to run the scripts.
 
 **Note**: These scripts require Python 3.10 or newer.
 
 
 ## Setting Up
 
-Before running, use Poetry to install a virtualenv containing the dependencies.
-This can be done by using the `poetry.sh` (or `poetry.ps1`) script contained in
-the `tools/` directory at the root of the `mongo-c-driver` repository:
-
-```sh
-./tools/poetry.sh install --with=dev
-```
-
-Or with PowerShell:
-
-```pwsh
-./tools/poetry.ps1 install --with=dev
-```
+`uv` is required to run Python scripts. See ["Installing uv"](https://docs.astral.sh/uv/getting-started/installation/) for instructions on how to obtain `uv`.
 
 
 ## Running the Generator
 
-The package defines a program `mc-evg-generate`, which can be run within the
-virtualenv. This can be done via Poetry as well, following the setup:
+The package provides the `mc-evg-generate` [entry point](https://packaging.python.org/en/latest/specifications/entry-points):
 
 ```sh
-./tools/poetry.sh run mc-evg-generate
+uv run --frozen mc-evg-generate
 ```
 
 This command will ready the generation files and generate a new set of Evergreen

-To build the documentation, it is recommended to use the Poetry-managed Python

+To build the documentation, it is recommended to run Sphinx commands through `uv`:
 
-```sh

-Then, execute `sphinx-build` in the Python environment, using the paths to the
-documentation to be generated:
