 ## Development/contributing
 
-### For developers at NSIDC
-
-For developers at NSIDC, the [seaice_ecdr_vm
-repository](https://bitbucket.org/nsidc/seaice_ecdr_vm/src/main/) provides the
-NSIDC VM configuration for this project.
-
-An initial copy of the pm_icecon "cdr" generation can be executed from the VM directory:
-
-`~/seaice_ecdr/`
-
-using the cli.sh command:
-
-```
-./scripts/cli.sh bootstrap amsr2 --date 2022-08-01 --hemisphere north --output-dir /tmp/ --resolution 12
-```
-
-### Adding dependencies
-
-To add new dependencies to this project, update the `environment.yml` file with
-the new dependency. Then update your conda environment:
-
-```
-$ mamba env update
-```
-
-Once the conda environment has been updated, lock the environment using `conda-lock`:
-
-```
-$ conda-lock
-```
-
-Commit the changes for the `environment.yml` and the `conda-lock.yml` files.
-
-
-### Running tests/CI
-
-#### Linting / formatting
-This project uses [pre-commit](https://pre-commit.com/) to run pre-commit hooks
-that check and format this project's code for stylistic consistency (using
-`ruff` and `black`) .
-
-The pre-commit configuration for this project can be found in
-`.pre-commit-config.yaml`. Configuration for specific tools (e.g., `mypy`) is
-given in the included `pyproject.toml`.
-
-For more information about using `pre-commit`, please sese the [Scientific
-Python Library Development Guide's section on
-pre-commit](https://learn.scientific-python.org/development/guides/gha-basic/#pre-commit).
-
-To install pre-commit to run checks for each commit you make:
-
-```
-$ pre-commit install
-```
-
-To manually run the pre-commit hooks without a commit:
-
-```
-$ pre-commit run --all-files
-```
-
-#### Running unit tests
-
-Use `pytest` to run unit tests:
-
-```
-$ python -m pytest
-```
-
-#### Type-checking
-
-Use `mypy` to run static typechecking
-
-```
-$ mypy
-```
