 Use `pyenv` to install the following Python versions for testing.
 ```bash
-pyenv install 3.7 3.8 3.9
+pyenv install 3.8 3.9 3.10
 ```
 
 You will probably want to set one of these versions as your global Python version. This will be the version of Python that is used when you run `python` commands in your terminal.
 For example, to set Python 3.9 as your global Python version, run the following command:
 ```bash
-pyenv global 3.9
+pyenv global 3.10
 ```
 
 Within the `tempo/python` folder, run the below command to create a `.python-version` file that will tell `pyenv` which Python version to use when running commands in this directory:
 ```bash
-pyenv local 3.7 3.8 3.9
+pyenv local 3.8 3.9 3.10
 ```
 
 This allows `tox` to create virtual environments using any of the Python versions listed in the `.python-version` file.

 ### Run additional checks locally
 `tox` has special environments for additional checks that must be performed as part of the PR process. These include formatting, linting, type checking, etc.
 These environments are also defined in the `tox.ini`file and skip installing dependencies listed in the `requirements.txt` file and building the distribution when those are not required . They can be specified using the `-e` flag:
-* format
 * lint
 * type-check
+* build-dist
+* build-docs
 * coverage-report
