 # NOAA/NASA Domain Specific Language middleware
 
-NDSL is a middleware for climate and weather modelling developed jointly by NOAA and NASA. The middleware brings together [GT4Py](https://github.com/GridTools/gt4py/) (the `cartesian` flavor), ETH CSCS's stencil DSL, and [DaCE](https://github.com/spcl/dace/), ETH SPCL's data flow framework, both developed for high-performance and portability. On top of those pillars, NDSL deploys a series of optimized APIs for common operations (Halo exchange, domain decomposition, MPI...), a set of bespoke optimizations for the models targeted by the middleware and tools to port existing models.

-Historically NDSL was developed to port the FV3 dynamical core on the cube-sphere. Therefore, the middleware ships with ready-to-execute specialization for models based on cube-sphere grid and FV-based model in particular.
+Historically, NDSL was developed to port the FV3 dynamical core on the cubed-sphere. Therefore, the middleware ships with ready-to-execute specialization for models based on cubed-sphere grids and FV-based models in particular.
 
 ## Quickstart
 
-Recommended Python is `3.11.x` all other dependencies will be pulled during install.
+Currently, NDSL requires Python version `3.11.x`. All other dependencies installed during package installation. We recommend using virtual (or conda) environment.
 
-NDSL submodules `gt4py` and `dace` to point to vetted versions, use `git clone --recurse-submodule`.
+```shell
+# We have submodules for GT4Py and DaCe. Don't forget to pull them
+git clone --recurse-submodules git@github.com:NOAA-GFDL/NDSL.git
 
-NDSL is __NOT__ available on `pypi`. Installation of the package has to be local, via `pip install ./NDSL` (`-e` supported). The packages has a few options:
+cd NDSL/
 
-- `ndsl[test]`: installs the test packages (based on `pytest`)
-- `ndsl[demos]`: installs extra requirements to run [NDSL examples](./examples/NDSL/)
-- `ndsl[docs]`: installs extra requirements to build the docs
-- `ndsl[develop]`: installs tools for development, docs, and tests.
+# We strongly recommend using a virtual environment (or conda)
+python -m venv .venv/
+source ./venv/bin/activate
+
+# Choose pip install -e .[develop] if you'd like to contribute
+pip install .[demos]
+```
 
-Tests are available via:
+Now, checkout [examples/NDSL](./examples/NDSL/) and ran through the Jupyter notebooks. Note that you have to install NDSL locally, as it is not available on `pypi`.
 
-- `pytest -x test`: running CPU serial tests (GPU as well if `cupy` is installed)
-- `mpirun -np 6 pytest -x test/mpi`: running CPU parallel tests (GPU as well if `cupy` is installed)
+## The slightly longer version
 
-## Requirements & supported compilers
+NDSL is under active development and may only work with specific setups. This is what we know works for us.
 
-For CPU backends:
+### Requirements and supported compilers
 
-- 3.11.x >= Python < 3.12.x
-- Compilers:
-  - GNU 11.2+
+The run the CPU backends you will need:
 
-For GPU backends (the above plus):
+- Python: 3.11.x
+- CXX compiler:  GNU 11.2+
+- Libraries: MPI
 
+To run the GPU backends, you'll need:
+
+- Python: 3.11.x
+- CXX compiler:  GNU 11.2+
+- Libraries: MPI compiled with CUDA support
 - CUDA 11.2+
 - Python package:
   - `cupy` (latest with proper driver support [see install notes](https://docs.cupy.dev/en/stable/install.html))
-- Libraries:
-  - MPI compiled with cuda support
+
+### Installation options
+
+See [quickstart](#quickstart) above on how to pull and setup a virtual environment. The packages has a few options:
+
+- `ndsl[test]`: extra dependencies to run tests (based on `pytest`)
+- `ndsl[demos]`: extra dependencies to run [NDSL examples](./examples/NDSL/)
+- `ndsl[docs]`: extra dependencies to build the docs
+- `ndsl[develop]`: installs tools for development, docs, and tests.
+
+### Running tests
+
+Tests are available via `pytest` (don't forget to install the `test` or `develop` extras). Before you run tests, make sure to create expected input files:
+
+```bash
+python tests/grid/generate_eta_files.py
+```
+
+To run serial tests on CPU (GPU tests also run if `cupy` is available)
+
+```bash
+pytest tests/
+```
+
+To run parallel tests on CPU (GPU tests also run if `cupy` is available)
+
+```bash
+mpirun -np 6 pytest tests/mpi
+```
 
 ## Development
 
 ### Code/contribution guidelines
 
-TBD
+1. Code quality is enforced by `pre-commit` (which is part of the "develop" extra). Run `pre-commit install`  to install the pre-commit hooks locally or make sure to run `pre-commit run -a`  before submitting a pull request.
+2. While we don't strictly enforce type hints, we add them on new code.
+3. Pull requests have to merged as "squash merge" to keep the `git` history clean.
 
 ### Documentation
 
 We are using [Material for MkDocs](https://squidfunk.github.io/mkdocs-material/), which allows us to write the docs in Markdown files and optionally serve it as a static site.
