+/**
+ * The Pipeline class provides a flexible and expressive framework for building complex data
+ * transformation and query pipelines for Firestore.
+ *
+ * <p>A pipeline takes data sources, such as Firestore collections or collection groups, and applies
+ * a series of stages that are chained together. Each stage takes the output from the previous stage
+ * (or the data source) and produces an output for the next stage (or as the final output of the
+ * pipeline).
+ *
+ * <p>Expressions from {@link com.google.cloud.firestore.pipeline.expressions} can be used within
+ * each stages to filter and transform data through the stage.
+ *
+ * <p>NOTE: The chained stages do not prescribe exactly how Firestore will execute the pipeline.
+ * Instead, Firestore only guarantees that the result is the same as if the chained stages were
+ * executed in order.
+ *
+ * <p>Usage Examples:
+ *
+ * <pre>{@code
+ * Firestore firestore; // A valid firestore instance.
+ *
+ * // Example 1: Select specific fields and rename 'rating' to 'bookRating'
+ * List<PipelineResult> results1 = firestore.pipeline()
+ *     .collection("books")
+ *     .select("title", "author", field("rating").as("bookRating"))
+ *     .execute()
+ *     .get();
+ *
+ * // Example 2: Filter documents where 'genre' is "Science Fiction" and 'published' is after 1950
+ * List<PipelineResult> results2 = firestore.pipeline()
+ *     .collection("books")
+ *     .where(and(eq("genre", "Science Fiction"), gt("published", 1950)))
+ *     .execute()
+ *     .get();
+ * // Same as above but using methods on expressions as opposed to static functions.
+ * results2 = firestore.pipeline()
+ *     .collection("books")
+ *     .where(and(field("genre").eq("Science Fiction"), field("published").gt(1950)))
+ *     .execute()
+ *     .get();
+ *
+ * // Example 3: Calculate the average rating of books published after 1980
+ * List<PipelineResult> results3 = firestore.pipeline()
+ *     .collection("books")
+ *     .where(gt("published", 1980))
+ *     .aggregate(avg("rating").as("averageRating"))
+ *     .execute()
+ *     .get();
