 ## Usage
 
-To enable source code linking with Logfire, you need to configure your project. Here's how:
+Here's an example:
 
 ```python
 import logfire
 
 logfire.configure(
     code_source=logfire.CodeSource(
-        repository='https://github.com/pydantic/logfire',
-        revision='main',
-        root_path='.',
+        repository='https://github.com/pydantic/logfire',  #(1)!
+        revision='main',  #(2)!
+        root_path='.',  #(3)!
     )
 )
 ```
 
-You can check more about it on the [`logfire.CodeSource`][logfire.CodeSource] on our API reference.
+1. The URL of the repository e.g. `https://github.com/pydantic/logfire`.
+2. The specific branch, tag, or commit hash to link to e.g. `main`.
+3. The path to the root of the repository. If your code is in a subdirectory, you can specify it here.

+You can learn more in our [`logfire.CodeSource`][logfire.CodeSource] API reference.
 
 ## Alternative Configuration
 
-Alternatively, you can configure these settings using the [`OTEL_RESOURCE_ATTRIBUTES`][otel-resource-attributes] environment variable:
+For other OpenTelemetry SDKs, you can configure these settings using resource attributes, e.g. by setting the
+[`OTEL_RESOURCE_ATTRIBUTES`][otel-resource-attributes] environment variable:
 
 ```
 OTEL_RESOURCE_ATTRIBUTES=vcs.repository.url.full=https://github.com/pydantic/platform
 OTEL_RESOURCE_ATTRIBUTES=${OTEL_RESOURCE_ATTRIBUTES},vcs.repository.ref.revision=main
 OTEL_RESOURCE_ATTRIBUTES=${OTEL_RESOURCE_ATTRIBUTES},vcs.root.path=.
