 ### Secrets
 - When to use a [Personal Access Token (PAT)](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token) vs the [GITHUB_TOKEN](https://docs.github.com/en/actions/security-guides/automatic-token-authentication) generated for the action?
 
     The `GITHUB_TOKEN` is used by default.  In most cases it is sufficient for what you need.
-    
+
     If you expect the workflow to result in a commit to that should retrigger workflows, you will need to use a Personal Access Token for the bot to commit the file. When using the GITHUB_TOKEN, the resulting commit will not trigger another GitHub Actions Workflow run. This is due to limitations set by GitHub. See [the docs](https://docs.github.com/en/actions/security-guides/automatic-token-authentication#using-the-github_token-in-a-workflow) for a more detailed explanation.
 
     For example, we must use a PAT in our workflow to commit a new changelog yaml file for bot PRs.  Once the file has been committed to the branch, it should retrigger the check to validate that a changelog exists on the PR.  Otherwise, it would stay in a failed state since the check would never retrigger.

+# **what?**
+# This workflow models the performance characteristics of a point in time in dbt.
+# It runs specific dbt commands on committed projects multiple times to create and
+# commit information about the distribution to the current branch. For more information
+# see the readme in the performance module at /performance/README.md.
+#
+# **why?**
+# When developing new features, we can take quick performance samples and compare
+# them against the commited baseline measurements produced by this workflow to detect
+# some performance regressions at development time before they reach users.
+#
+# **when?**
+# This is only run once directly after each release (for non-prereleases). If for some
+# reason the results of a run are not satisfactory, it can also be triggered manually.

+# **what?**
+# This workflow will test all test(s) at the input path given number of times to determine if it's flaky or not.  You can test with any supported OS/Python combination.
+# This is batched in 10 to allow more test iterations faster.
+
+# **why?**
+# Testing if a test is flaky and if a previously flaky test has been fixed.  This allows easy testing on supported python versions and OS combinations.
+
+# **when?**

 * Sometimes flake8 complains about lines that are actually fine, in which case you can put a comment on the line such as: # noqa or # noqa: ANNN, where ANNN is the error code that flake8 issues.
 * To collect output for `CProfile`, run dbt with the `-r` option and the name of an output file, i.e. `dbt -r dbt.cprof run`. If you just want to profile parsing, you can do: `dbt -r dbt.cprof parse`. `pip` install `snakeviz` to view the output. Run `snakeviz dbt.cprof` and output will be rendered in a browser window.

+## Adding or modifying a CHANGELOG Entry
 
 We use [changie](https://changie.dev) to generate `CHANGELOG` entries. **Note:** Do not edit the `CHANGELOG.md` directly. Your modifications will be lost.
 
 Follow the steps to [install `changie`](https://changie.dev/guide/installation/) for your system.
 
-Once changie is installed and your PR is created, simply run `changie new` and changie will walk you through the process of creating a changelog entry.  Commit the file that's created and your changelog entry is complete!
+Once changie is installed and your PR is created for a new feature, simply run the following command and changie will walk you through the process of creating a changelog entry:
+
+```shell
+changie new
+```
+
+Commit the file that's created and your changelog entry is complete!
+
+If you are contributing to a feature already in progress, you will modify the changie yaml file in dbt/.changes/unreleased/ related to your change. If you need help finding this file, please ask within the discussion for the pull request!
 
 You don't need to worry about which `dbt-core` version your change will go into. Just create the changelog entry with `changie`, and open your PR against the `main` branch. All merged changes will be included in the next minor version of `dbt-core`. The Core maintainers _may_ choose to "backport" specific changes in order to patch older minor versions. In that case, a maintainer will take care of that backport after merging your PR, before releasing the new version of `dbt-core`.

+# RelationConfig
+This package serves as an initial abstraction for managing the inspection of existing relations and determining
+changes on those relations. It arose from the materialized view work and is currently only supporting 
+materialized views for Postgres and Redshift as well as dynamic tables for Snowflake. There are three main
+classes in this package.
+
+## RelationConfigBase
+This is a very small class that only has a `from_dict()` method and a default `NotImplementedError()`. At some
+point this could be replaced by a more robust framework, like `mashumaro` or `pydantic`.
+
+## RelationConfigChange
+This class inherits from `RelationConfigBase` ; however, this can be thought of as a separate class. The subclassing
+merely points to the idea that both classes would likely inherit from the same class in a `mashumaro` or
+`pydantic` implementation. This class is much more restricted in attribution. It should really only
+ever need an `action` and a `context`. This can be though of as being analogous to a web request. You need to
+know what you're doing (`action`: 'create' = GET, 'drop' = DELETE, etc.) and the information (`context`) needed
+to make the change. In our scenarios, the context tends to be an instance of `RelationConfigBase` corresponding
+to the new state.
+
+## RelationConfigValidationMixin
+This mixin provides optional validation mechanics that can be applied to either `RelationConfigBase` or
+`RelationConfigChange` subclasses. A validation rule is a combination of a `validation_check`, something
+that should evaluate to `True`, and an optional `validation_error`, an instance of `DbtRuntimeError`
+that should be raised in the event the `validation_check` fails. While optional, it's recommended that
+the `validation_error` be provided for clearer transparency to the end user.

-TODO
+# Adding a new command
+
+## `main.py`
+Add the new command with all necessary decorators. Every command will need at minimum:
+- a decorator for the click group it belongs to which also names the command
+- the postflight decorator (must come before other decorators from the `requires` module for error handling)
+- the preflight decorator
+```py
+@cli.command("my-new-command")
+@requires.postflight
+@requires.preflight
+def my_new_command(ctx, **kwargs):
+    ...
+```
+
+## `types.py`
+Add an entry to the `Command` enum with your new command. Commands that are sub-commands should have entries
+that represent their full command path (e.g. `source freshness -> SOURCE_FRESHNESS`, `docs serve -> DOCS_SERVE`).
+
+## `flags.py`
+Add the new command to the dictionary within the `command_args` function.
+
+# Exception Handling
+
+## `requires.py`
+
+### `postflight`
+In the postflight decorator, the click command is invoked (i.e. `func(*args, **kwargs)`) and wrapped in a `try/except` block to handle any exceptions thrown.
+Any exceptions thrown from `postflight` are wrapped by custom exceptions from the `dbt.cli.exceptions` module (i.e. `ResultExit`, `ExceptionExit`) to instruct click to complete execution with a particular exit code.
+
+Some `dbt-core` handled exceptions have an attribute named `results` which contains results from running nodes (e.g. `FailFastError`). These are wrapped in the `ResultExit` exception to represent runs that have failed in a way that `dbt-core` expects.
+If the invocation of the command does not throw any exceptions but does not succeed, `postflight` will still raise the `ResultExit` exception to make use of the exit code.
+These exceptions produce an exit code of `1`.
+
+Exceptions wrapped with `ExceptionExit` may be thrown by `dbt-core` intentionally (i.e. an exception that inherits from `dbt.exceptions.Exception`) or unintentionally (i.e. exceptions thrown by the python runtime). In either case these are considered errors that `dbt-core` did not expect and are treated as genuine exceptions.
+These exceptions produce an exit code of `2`.
+
+If no exceptions are thrown from invoking the command and the command succeeds, `postflight` will not raise any exceptions.
+When no exceptions are raised an exit code of `0` is produced.
+
+## `main.py`
+
+### `dbtRunner`
+`dbtRunner` provides a programmatic interface for our click CLI and wraps the invocation of the click commands to handle any exceptions thrown.
+
+`dbtRunner.invoke` should ideally only ever return an instantiated `dbtRunnerResult` which contains the following fields:
+- `success`: A boolean representing whether the command invocation was successful
+- `result`: The optional result of the command invoked. This attribute can have many types, please see the definition of `dbtRunnerResult` for more information
+- `exception`: If an exception was thrown during command invocation it will be saved here, otherwise it will be `None`. Please note that the exceptions held in this attribute are not the exceptions thrown by `preflight` but instead the exceptions that `ResultExit` and `ExceptionExit` wrap
+
+Programmatic exception handling might look like the following:
+```python
+res = dbtRunner().invoke(["run"])
+if not res.success:
+    ...
+if type(res.exception) == SomeExceptionType:
+    ...
+```
+
+## `dbt/tests/util.py`
+
+### `run_dbt`
+In many of our functional and integration tests, we want to be sure that an invocation of `dbt` raises a certain exception.
+A common pattern for these assertions:
+```python
+class TestSomething:
+    def test_something(self, project):
+        with pytest.raises(SomeException):
+            run_dbt(["run"])
+```
+To allow these tests to assert that exceptions have been thrown, the `run_dbt` function will raise any exceptions it recieves from the invocation of a `dbt` command.
