 - [`task`](core/dbt/task): Set forth the actions that dbt can perform when invoked
 
 ### Invoking dbt
 
-There are two supported ways of invoking dbt: from the command line and using an RPC server.
-
-The "tasks" map to top-level dbt commands. So `dbt run` => task.run.RunTask, etc. Some are more like abstract base classes (GraphRunnableTask, for example) but all the concrete types outside of task/rpc should map to tasks. Currently one executes at a time. The tasks kick off their “Runners” and those do execute in parallel. The parallelism is managed via a thread pool, in GraphRunnableTask.

 ## Adapters
 
-dbt uses an adapter-plugin pattern to extend support to different databases, warehouses, query engines, etc. The four core adapters that are in the main repository, contained within the [`plugins`](plugins) subdirectory, are: Postgres Redshift, Snowflake and BigQuery. Other warehouses use adapter plugins defined in separate repositories (e.g. [dbt-spark](https://github.com/dbt-labs/dbt-spark), [dbt-presto](https://github.com/dbt-labs/dbt-presto)).
+dbt uses an adapter-plugin pattern to extend support to different databases, warehouses, query engines, etc. For testing and development purposes, the dbt-postgres plugin lives alongside the dbt-core codebase, in the [`plugins`](plugins) subdirectory. Like other adapter plugins, it is a self-contained codebase and package that builds on top of dbt-core.
 
-Each adapter is a mix of python, Jinja2, and SQL. The adapter code also makes heavy use of Jinja2 to wrap modular chunks of SQL functionality, define default implementations, and allow plugins to override it.

 ### Defining the problem
 
-If you have an idea for a new feature or if you've discovered a bug in `dbt`, the first step is to open an issue. Please check the list of [open issues](https://github.com/dbt-labs/dbt/issues) before creating a new one. If you find a relevant issue, please add a comment to the open issue instead of creating a new one. There are hundreds of open issues in this repository and it can be hard to know where to look for a relevant open issue. **The `dbt` maintainers are always happy to point contributors in the right direction**, so please err on the side of documenting your idea in a new issue if you are unsure where a problem statement belongs.

 > **Note:** All community-contributed Pull Requests _must_ be associated with an open issue. If you submit a Pull Request that does not pertain to an open issue, you will be asked to create an issue describing the problem before the Pull Request can be reviewed.
 
 ### Discussing the idea
 
-After you open an issue, a `dbt` maintainer will follow up by commenting on your issue (usually within 1-3 days) to explore your idea further and advise on how to implement the suggested changes. In many cases, community members will chime in with their own thoughts on the problem statement. If you as the issue creator are interested in submitting a Pull Request to address the issue, you should indicate this in the body of the issue. The `dbt` maintainers are _always_ happy to help contributors with the implementation of fixes and features, so please also indicate if there's anything you're unsure about or could use guidance around in the issue.

 ### Submitting a change
 
-If an issue is appropriately well scoped and describes a beneficial change to the `dbt` codebase, then anyone may submit a Pull Request to implement the functionality described in the issue. See the sections below on how to do this.
+If an issue is appropriately well scoped and describes a beneficial change to the `dbt-core` codebase, then anyone may submit a Pull Request to implement the functionality described in the issue. See the sections below on how to do this.
 
-The `dbt` maintainers will add a `good first issue` label if an issue is suitable for a first-time contributor. This label often means that the required code change is small, limited to one database adapter, or a net-new addition that does not impact existing functionality. You can see the list of currently open issues on the [Contribute](https://github.com/dbt-labs/dbt/contribute) page.

 Here's a good workflow:
 - Comment on the open issue, expressing your interest in contributing the required code change
 - Outline your planned implementation. If you want help getting started, ask!
-- Follow the steps outlined below to develop locally. Once you have opened a PR, one of the `dbt` maintainers will work with you to review your code.
-- Add a test! Tests are crucial for both fixes and new features alike. We want to make sure that code works as intended, and that it avoids any bugs  previously encountered. Currently, the best resource for understanding `dbt`'s [unit](test/unit) and [integration](test/integration) tests is the tests themselves. One of the maintainers can help by pointing out relevant examples.

 ### Using issue labels
 
-The `dbt` maintainers use labels to categorize open issues. Some labels indicate the databases impacted by the issue, while others describe the domain in the `dbt` codebase germane to the discussion. While most of these labels are self-explanatory (eg. `snowflake` or `bigquery`), there are others that are worth describing.

-- **Trunks** are where active development of the next release takes place. There is one trunk named `develop` at the time of writing this, and will be the default branch of the repository.
-- **Release Branches** track a specific, not yet complete release of `dbt`. Each minor version release has a corresponding release branch. For example, the `0.11.x` series of releases has a branch called `0.11.latest`. This allows us to release new patch versions under `0.11` without necessarily needing to pull them into the latest version of `dbt`.

-Since `dbt` works with a number of different databases, you will need to supply credentials for one or more of these databases in your test environment. Most organizations don't have access to each of a BigQuery, Redshift, Snowflake, and Postgres database, so it's likely that you will be unable to run every integration test locally. Fortunately, dbt Labs provides a CI environment with access to sandboxed Redshift, Snowflake, BigQuery, and Postgres databases. See the section on [_Submitting a Pull Request_](#submitting-a-pull-request) below for more information on this CI setup.

-`dbt` uses test credentials specified in a `test.env` file in the root of the repository for non-Postgres databases.

+# Events Module
+
+The Events module is the implmentation for structured logging. These events represent both a programatic interface to dbt processes as well as human-readable messaging in one centralized place. The centralization allows for leveraging mypy to enforce interface invariants across all dbt events, and the distinct type layer allows for decoupling events and libraries such as loggers.
+
+# Using the Events Module
+The event module provides types that represent what is happening in dbt in `events.types`. These types are intended to represent an exhaustive list of all things happening within dbt that will need to be logged, streamed, or printed. To fire an event, `events.functions::fire_event` is the entry point to the module from everywhere in dbt.
+
+# Adding a New Event
+In `events.types` add a new class that represents the new event. All events must be a dataclass with, at minimum, a code.  You may also include some other values to construct downstream messaging. Only include the data necessary to construct this message within this class. You must extend all destinations (e.g. - if your log message belongs on the cli, extend `Cli`) as well as the loglevel this event belongs to.  This system has been designed to take full advantage of mypy so running it will catch anything you may miss.
+
+## Required for Every Event
+
+- a string attribute `code`, that's unique across events
+- assign a log level by extending `DebugLevel`, `InfoLevel`, `WarnLevel`, or `ErrorLevel`
+- a message()
+- extend `File` and/or `Cli` based on where it should output
+
+Example
+```
+@dataclass
+class PartialParsingDeletedExposure(DebugLevel, Cli, File):
+    unique_id: str
+    code: str = "I049"
+
+    def message(self) -> str:
+        return f"Partial parsing: deleted exposure {self.unique_id}"
+
+```
+
+## Optional (based on your event)
+
+- Events associated with node status changes must have `report_node_data` passed in and be extended with `NodeInfo`
+- define `asdict` if your data is not serializable to json
+
+Example
+```
+@dataclass
+class SuperImportantNodeEvent(InfoLevel, File, NodeInfo):
+    node_name: str
+    run_result: RunResult
+    report_node_data: ParsedModelNode  # may vary
+    code: str = "Q036"
+
+    def message(self) -> str:
+        return f"{self.node_name} had overly verbose result of {run_result}"
+
+    @classmethod
+    def asdict(cls, data: list) -> dict:
+        return dict((k, str(v)) for k, v in data)
+
+```
+
+All values other than `code` and `report_node_data` will be included in the `data` node of the json log output.
+
+Once your event has been added, add a dummy call to your new event at the bottom of `types.py` and also add your new Event to the list `sample_values` in `test/unit/test_events.py'.
+
+# Adapter Maintainers
+To integrate existing log messages from adapters, you likely have a line of code like this in your adapter already:
+```python
+from dbt.logger import GLOBAL_LOGGER as logger
+```
+
+Simply change it to these two lines with your adapter's database name, and all your existing call sites will now use the new system for v1.0:
+```python
+from dbt.events import AdapterLogger
+logger = AdapterLogger("<database name>")
+# e.g. AdapterLogger("Snowflake")
+```
