+# :construction: LLM Foundry Registry
+
+Some components of LLM Foundry are registrable. This means that you can register options for these components, and then use them in your yaml config, without forking the library.
+
+## How to register
+
+There are a few ways to register a new component:
+
+### Python entrypoints
+
+You can specify registered components via a Python entrypoint if you are building your own package with registered components.
+
+For example, the following would register the `WandBLogger` class, under the key `wandb`, in the `llm_foundry.loggers` registry:
+
+<!--pytest.mark.skip-->
+```yaml
+[build-system]
+requires = ["setuptools>=42", "wheel"]
+build-backend = "setuptools.build_meta"
+
+[project]
+name = "foundry_registry"
+version = "0.1.0"
+dependencies = [
+    "mosaicml",
+    "llm-foundry",
+]
+
+[project.entry-points."llm_foundry.loggers"]
+my_logger = "foundry_registry.loggers:MyLogger"
+```
+
+### Direct call to register
+
+You can also register a component directly in your code:
+
+<!--pytest.mark.skip-->
+```python
+from composer.loggers import LoggerDestination
+from llmfoundry.registry import loggers
+
+class MyLogger(LoggerDestination):
+    pass
+
+loggers.register("my_logger", func=MyLogger)
+```
+
+### Decorators
+
+You can also use decorators to register components directly from your code:
+
+<!--pytest.mark.skip-->
+```python
+from composer.loggers import LoggerDestination
+from llmfoundry.registry import loggers
+
+@loggers.register("my_logger")
+class MyLogger(LoggerDestination):
+    pass
+```
+
+For both the direct call and decorator approaches, if using the LLM Foundry train/eval scripts, you will need to provide the `code_paths` argument, which is a list of files need to execute in order to register your components. For example, you may have a file called `foundry_imports.py` that contains the following:
+
+<!--pytest.mark.skip-->
+```python
+from foundry_registry.loggers import MyLogger
+from llmfoundry.registry import loggers
+
+loggers.register("my_logger", func=MyLogger)
+```
+
+You would then provide `code_paths` to the train/eval scripts in your yaml config:
+
+<!--pytest.mark.skip-->
+```yaml
+...
+code_paths:
+  - foundry_imports.py
+...
+```
+
