+# PySCREAM
+
+PySCREAM is currently under heavy development and may contain some
+rough edges. If you encounter any issues, please report them on the
+team on
+[github discussions](https://github.com/E3SM-Project/E3SM/labels/eamxx).
+Likewise, if you have questions or would like to request features,
+please post them on the
+[github discussions](https://github.com/E3SM-Project/E3SM/labels/eamxx).
+
+## Quick Start
+
+For now, the only way to use pyscream is to either build it on your own
+or use our prebuilt conda binaries. We prefer for you to use the latter.
+In a conda environment, please use the following command to install it:
+
+```bash
+conda install -c mahf708 pyscream=0.0.2
+```
+
+It is recommended to use the latest version of pyscream, wich is
+currently 0.0.2. As you can see, it is a young package with a lot of
+potential. We do not guarantee that the API will remain stable, but we
+will try to document any changes as frequently as we could.
+
+## Examples
+
+We provide an example to demo calling the radiation process (RRTMGP).
+More examples are on the way. If you'd like to add your example,
+please feel free to submit a PR.
