 and databases and turns them into a unified resource. This allows users to spend more
 time on novel analysis and less time on data preparation.
 
+The project is focused on serving researchers, activists, journalists, policy makers,
+and small businesses that might not otherwise be able to afford access to this data
+from commercial sources and who may not have the time or expertise to do all the
+data processing themselves from scratch.
+
+We want to make this data accessible and easy to work with for as wide an audience as
+possible: anyone from a grassroots youth climate organizers working with Google
+sheets to university researchers with access to scalable cloud computing
+resources and everyone in between!
+
+PUDL is comprised of three core components:
+
+- **Raw Data Archives**
+
+  - PUDL `archives <https://github.com/catalyst-cooperative/pudl-archiver>`__
+    all the raw data inputs on `Zenodo <https://zenodo.org/communities/catalyst-cooperative/?page=1&size=20>`__
+    to ensure perminant, versioned access to the data. In the event that an agency
+    changes how they publish data or deletes old files, the ETL will still have access
+    to the original inputs. Each of the data inputs may have several different versions
+    archived, and all are assigned a unique DOI and made available through the REST API.
+    You can read more about the Raw Data Archives in the
+    `docs <https://catalystcoop-pudl.readthedocs.io/en/dev/intro.html#raw-data-archives>`__.
+- **ETL Pipeline**
+
+  - The ETL pipeline (this repo) ingests the raw archives, cleans them,
+    integrates them, and outputs them to a series of tables stored in SQLite Databases,
+    Parquet files, and pickle files (the Data Warehouse). Each release of the PUDL
+    Python package is embedded with a set of of DOIs to indicate which version of the
+    raw inputs it is meant to process. This process helps ensure that the ETL and it's
+    outputs are replicable. You can read more about the ETL in the
+    `docs <https://catalystcoop-pudl.readthedocs.io/en/dev/intro.html#the-etl-process>`__.
+- **Data Warehouse**
+
+  - The outputs from the ETL, sometimes called "PUDL outputs",
+    are stored in a data warehouse as a collection of SQLite and Parquet files so that
+    users can access the data without having to run any code. Learn more about how to
+    access the data `here <https://catalystcoop-pudl.readthedocs.io/en/dev/data_access.html>`__.

-It should be possible to run the ETL process on each data source independently

-Naming Conventions
--------------------------------------------------------------------------------
-    *There are only two hard problems in computer science: caching,
-    naming things, and off-by-one errors.*
-
-Use Consistent Names
-^^^^^^^^^^^^^^^^^^^^
-If two columns in different tables record the same quantity in the same units,
-give them the same name. That way if they end up in the same dataframe for
-comparison it's easy to automatically rename them with suffixes indicating
-where they came from. For example, net electricity generation is reported to
-both :doc:`FERC Form 1 <../data_sources/ferc1>` and :doc:`EIA 923
-<../data_sources/eia923>`, so we've named columns ``net_generation_mwh`` in
-each of those data sources. Similarly, give non-comparable quantities reported
-in different data sources **different** column names. This helps make it clear
-that the quantities are actually different.
-
-Follow Existing Conventions
-^^^^^^^^^^^^^^^^^^^^^^^^^^^
-We are trying to use consistent naming conventions for the data tables,
-columns, data sources, and functions. Generally speaking PUDL is a collection
-of subpackages organized by purpose (extract, transform, load, analysis,
-output, datastore…), containing a module for each data source. Each data source
-has a short name that is used everywhere throughout the project and is composed of
-the reporting agency and the form number or another identifying abbreviation:
-``ferc1``, ``epacems``, ``eia923``, ``eia861``, etc. See the :doc:`naming
-conventions <naming_conventions>` document for more details.
