+## Applying Model Tags
+
+### Database / Schema level tags
+
+Database and schema tags are applied via the `add_database_or_schema_tags` macro.  These tags are inherited by their downstream objects.  To add/modify tags call the appropriate tag set function within the macro.
+
+```
+{{ set_database_tag_value('SOME_DATABASE_TAG_KEY','SOME_DATABASE_TAG_VALUE') }}
+{{ set_schema_tag_value('SOME_SCHEMA_TAG_KEY','SOME_SCHEMA_TAG_VALUE') }}
+```
+
+### Model tags
+
+To add/update a model's snowflake tags, add/modify the `meta` model property under `config`.  Only table level tags are supported at this time via DBT.
+
+```
+{{ config(
+    ...,
+    meta={
+        'database_tags':{
+            'table': {
+                'PURPOSE': 'SOME_PURPOSE'
+            }
+        }
+    },
+    ...
+) }}
+```
+
+By default, model tags are not pushed to snowflake on each load.  You can push a tag update for a model by specifying the `UPDATE_SNOWFLAKE_TAGS` project variable during a run.
+
+```
+dbt run --var '{"UPDATE_SNOWFLAKE_TAGS":True}' -s models/core/core__fact_swaps.sql
+```
+
+### Querying for existing tags on a model in snowflake
+
+```
+select *
+from table(xyz.information_schema.tag_references('xyz.core.fact_blocks', 'table'));
+```

+# Welcome to the Flipside Crypto xyz Models Documentation
+
+## **What does this documentation cover?**
+The documentation included here details the design of the xyz
+ tables and views available via [Flipside Crypto.](https://flipsidecrypto.xyz/) For more information on how these models are built, please see [the github repository.](https://github.com/flipsideCrypto/xyz-models/)
+
+## **How do I use these docs?**
+The easiest way to navigate this documentation is to use the Quick Links below. These links will take you to the documentation for each table, which contains a description, a list of the columns, and other helpful information.
+
+If you are experienced with dbt docs, feel free to use the sidebar to navigate the documentation, as well as explore the relationships between tables and the logic building them.
+
+There is more information on how to use dbt docs in the last section of this document.
+
+## **Quick Links to Table Documentation**
+
+**Click on the links below to jump to the documentation for each schema.**
+
+### Core Tables (`xyz`.`CORE`.`<table_name>`)
+
+**Dimension Tables:**
+
+
+**Fact Tables:**
+
+
+
+**Convenience Tables:**
+
+
+
+
+## **Data Model Overview**
+
+The xyz
+ models are built a few different ways, but the core fact tables are built using three layers of sql models: **bronze, silver, and gold (or core).**
+
+- Bronze: Data is loaded in from the source as a view
+- Silver: All necessary parsing, filtering, de-duping, and other transformations are done here
+- Gold (or core): Final views and tables that are available publicly
+
+The dimension tables are sourced from a variety of on-chain and off-chain sources.
+
+Convenience views (denoted ez_) are a combination of different fact and dimension tables. These views are built to make it easier to query the data.
+
+## **Using dbt docs**
+### Navigation
+
+You can use the ```Project``` and ```Database``` navigation tabs on the left side of the window to explore the models in the project.
+
+### Database Tab
+
+This view shows relations (tables and views) grouped into database schemas. Note that ephemeral models are *not* shown in this interface, as they do not exist in the database.
+
+### Graph Exploration
+
+You can click the blue icon on the bottom-right corner of the page to view the lineage graph of your models.
+
+On model pages, you'll see the immediate parents and children of the model you're exploring. By clicking the Expand button at the top-right of this lineage pane, you'll be able to see all of the models that are used to build, or are built from, the model you're exploring.
+
+Once expanded, you'll be able to use the ```--models``` and ```--exclude``` model selection syntax to filter the models in the graph. For more information on model selection, check out the [dbt docs](https://docs.getdbt.com/docs/model-selection-syntax).
+
+Note that you can also right-click on models to interactively filter and explore the graph.
