-## Getting Started
+## Documentation
 
-`ecs-logging-python` has formatters for the standard library
-[`logging`](https://docs.python.org/3/library/logging.html) module
-and the [`structlog`](https://www.structlog.org/en/stable/) package.
-
-## Standard Library `logging` Module
-
-```python
-import logging
-import ecs_logging
-
-# Get the Logger
-logger = logging.getLogger("app")
-logger.setLevel(logging.DEBUG)
-
-# Add an ECS formatter to the Handler
-handler = logging.StreamHandler()
-handler.setFormatter(ecs_logging.StdlibFormatter())
-logger.addHandler(handler)
-
-# Emit a log!
-logger.debug("Example message!", extra={"http.request.method": "get"})
-```
-```json
-{
-    "@timestamp": "2020-03-20T18:11:37.895Z",
-    "ecs": {
-        "version": "1.6.0"
-    },
-    "http": {
-      "request": {
-        "method": "get"
-      }
-    },
-    "log": {
-        "level": "debug",
-        "logger": "app",
-        "origin": {
-            "file": {
-                "line": 14,
-                "name": "test.py"
-            },
-            "function": "func"
-        },
-        "original": "Example message!"
-    },
-    "message": "Example message!"
-}
-```
-
-##### Excluding Fields
-
-You can exclude fields from being collected by using the `exclude_fields` option
-in the `StdlibFormatter` constructor:
-
-```python
-from ecs_logging import StdlibFormatter
-
-formatter = StdlibFormatter(
-    exclude_fields=[
-        # You can specify individual fields to ignore:
-        "log.original",
-        # or you can also use prefixes to ignore
-        # whole categories of fields:
-        "process",
-        "log.origin",
-    ]
-)
-```
-
-##### Limiting Stack Traces
-
-The `StdlibLogger` automatically gathers `exc_info` into ECS `error.*` fields.
-If you'd like to control the number of stack frames that are included
-in `error.stack_trace` you can use the `stack_trace_limit` parameter
-(by default all frames are collected):
-
-```python
-from ecs_logging import StdlibFormatter
-
-formatter = StdlibFormatter(
-    # Only collects 3 stack frames
-    stack_trace_limit=3,
-)
-formatter = StdlibFormatter(
-    # Disable stack trace collection
-    stack_trace_limit=0,
-)
-```
-
-## Structlog Example
-
-```python
-import structlog
-import ecs_logging
-
-# Configure Structlog
-structlog.configure(
-    processors=[ecs_logging.StructlogFormatter()],
-    wrapper_class=structlog.BoundLogger,
-    context_class=dict,
-    logger_factory=structlog.PrintLoggerFactory(),
-)
-
-# Get the Logger
-logger = structlog.get_logger("app")
-
-# Add additional context
-logger = logger.bind(**{
-    "http": {
-        "version": "2",
-        "request": {
-            "method": "get",
-            "bytes": 1337,
-        },
-    },
-    "url": {
-        "domain": "example.com",
-        "path": "/",
-        "port": 443,
-        "scheme": "https",
-        "registered_domain": "example.com",
-        "top_level_domain": "com",
-        "original": "https://example.com",
-    }
-})
-
-# Emit a log!
-logger.debug("Example message!")
-```
-```json
-{
-  "@timestamp": "2020-03-26T13:08:11.728Z",
-  "ecs": {
-    "version": "1.6.0"
-  },
-  "http": {
-    "request": {
-      "bytes": 1337,
-      "method": "get"
-    },
-    "version": "2"
-  },
-  "log": {
-    "level": "debug"
-  },
-  "message": "Example message!",
-  "url": {
-    "domain": "example.com",
-    "original": "https://example.com",
-    "path": "/",
-    "port": 443,
