 ### QueryRef
 
 Rather than specifying a direct query string as shown in the example above,
 the function allows referencing a query from any arbitrary string within the Context or Status.

 # Example manifests
 
-You can run your function locally and test it using `crossplane beta render`
-with these example manifests.
+This directory contains a collection of practical examples to demonstrate the functionality. Each example is organized into a directory with a self-descriptive name.
 
-```shell
-# Run the function locally
-$ go run . --insecure --debug
-```
+## Usage
+
+To render a specific example, navigate to its directory and run the `make` command.
+
+Each example provides a unique `composition.yaml` file that highlights a specific function usage scenario.
+
+The Makefile in the examples directory provides a simple `render` target to
+streamline rendering Crossplane compositions.
+
+To enable a successful query, update `secrets/azure-creds.yaml` with
+your valid Azure credentials.
+
+## Example
+
+For instance, the static-query-to-context-field directory demonstrates how to use a static query to populate a specific context field.
 
 ```shell
-# Then, in another terminal, call it with these example manifests
-$ crossplane render example/xr.yaml example/composition.yaml example/functions-dev.yaml --function-credentials=example/secrets/azure-creds.yaml -r
+$ cd queryref-from-environment
+$ make
+crossplane render ../xr.yaml composition.yaml ./functions.yaml --function-credentials=../secrets/azure-creds.yaml --extra-resources=envconfig.yaml  -rc
