-
-Let's start with an example. Create a package that split sentences into words and counts the number of characters in each word.
-
-##### 1. Create the Package file
-
-Create a fresh project directory `split-sentence` with two subdirectories: `packages` and `sentence`:
-
-```bash
-$ mkdir -p split-sentence/packages/sentence
-$ cd split-sentence/packages/sentence
-```
-
-Inside the `sentence` directory and create the `sdf-package.yaml` and add the following content:
-
-```yaml
-#sdf-package.yaml
-apiVersion: 0.5.0
-
-meta:
-  name: sentence-pkg
-  version: 0.1.0
-  namespace: example
-
-functions:
-
-  sentence-to-words:
-    operator: flat-map
-    inputs:
-      - name: sentence
-        type: string
-    output:
-      type: string
-
-  augment-count:
-    operator: map
-    inputs:
-      - name: word
-        type: string
-    output:
-      type: string
-
-dev:
-  converter: raw
-```
-
-##### 2. Generate the Package Project
-
-Use SDF generate command to build the project:
-
-```bash copy="fl"
-$ sdf generate
-```
-
-The generator created several directories and files that we'll edit next.
-
-
-##### 3. Add the Custom Code
-
-First, let's update the first function, `sentence-to-words`. Open `rust/sentence-to-words/src/lib.rs` and update the function body with the following code:
-
-```rust
-pub(crate) fn sentence_to_words(sentence: String) -> Result<Vec<String>> {
-    Ok(sentence.split_whitespace().map(String::from).collect())
-}
-```
-
-Next update `augment_count`. Open `rust/augment-count/src/lib.rs` and replace the function body:
-
-```rust
-pub(crate) fn augment_count(word: String) -> Result<String> {
-    Ok(format!("{}({})", word, word.chars().count()))
-}
-```
-
-Let's add some tests as well:
-
-```rust
-#[cfg(test)]
-mod test {
-    use super::*;
-
-    #[test]
-    fn test_augment_count() {
-        let input = "Hello".to_string();
-        let output = augment_count(input);
-        assert_eq!(output.unwrap(), "Hello(5)");
-    }
-}
-```
-
-We've implemented both functions; it's time to compile and test our work.
-
-
-##### 4. Build and Test the Package
-
-To build the package, run:
-
-```bash
-$ sdf build
-```
-
-Use `sdf test` interactive shell to test the code:
-
-```bash
-$ sdf test
-```
-
-In the test shell, you can view the functions available for testing:
-
-```bash copy="fl"
->> show functions
-sentence-to-words
-augment-count
-```
-
-Let's test `sentence-to-words` first:
-
-```bash copy="fl"
->> test function sentence-to-words --input "Hello World"
-Hello
-World
-```
-
-Next, test `augment-count`:
-
-```bash copy="fl"
->> test function augment-count --input "Hello"
-Hello(5)
-```
-
-You may also test the `rust` code via Cargo:
-
-```bash
-$ cd rust
-$ cargo test
-```
-
-The tests passed, and the package is now ready to use in the dataflow file.
-
 ## The Dataflow
 
 The **dataflow** imports functions, types, and states from one more package. Packages may also import components from others; however, dataflow maintains the final composition.
 
-
 #### `dataflow.yaml`
 
 The [SDF] command line tool uses the dataflow definition file `dataflow.yaml` to assemble the data application, and it has the following hierarchy:

 The dataflow file has other variants such as `window` and `partitions`, which are omitted for simplicity. For additional details check the [Dataflow file] section.
 
+# Getting started
 
-#### Create a Dataflow
-
-We'll import the package built in the [previous](#build-and-test-a-package) section to create the `split-sentence` dataflow.
-
-##### 1. Create the Dataflow file
-
-Create a dataflow file in the directory `split-sentence` directory:
-
-```bash
-$ cd split-sentence
-```
-
-Create the `dataflow.yaml` and add the following content:
-
-```yaml name="dataflow.yaml"
-apiVersion: 0.5.0
-
-meta:
-  name: split-sentence
-  version: 0.1.0
-  namespace: example
-
-imports:
-  - pkg: example/sentence-pkg@0.1.0
-    functions:
-      - name: sentence-to-words
-      - name: augment-count
-
-config:
-  converter: raw
-
-topics:
-  sentence:
-    schema:
-      value:
-        type: string
-        converter: raw
-  words:
-    schema:
-      value:
-        type: string
-        converter: raw
-
-services:
-  sentence-words:
-    sources:
-      - type: topic
-        id: sentence
-
-    transforms:
-      - operator: flat-map
-        uses: sentence-to-words
-      - operator: map
-        uses: augment-count
-
-    sinks:
-      - type: topic
-        id: words
-
-dev:
-  imports:
-    - pkg: example/sentence-pkg@0.1.0
-      path: ./packages/sentence
-```
-
-##### 2. Run the Dataflow
-
-Use `sdf` command line tool to run the dataflow:
-
-```bash copy="fl"
-$ sdf run --dev
-```
-
-Use `--dev` to ask the engine to change the path to the local package. Without this flag, the engine will look for the package in `InfinyOn Hub`.
-
-
-##### 3. Test the Dataflow
-
-1. Produce sentences to in `sentence` topic:
-
-```bash copy="fl"
-$ fluvio produce sentence
-```
-
-```bash
-Hello world
-Hi there
-```
-
-Consume from `words` to retrieve the result:
-
-```bash
-$ fluvio consume words -Bd
-```
+See [next section] for a quickstart.
 
-```bash
-Hello(5)
-world(5)
-Hi(2)
-there(5)
-```
-
-##### 4. Show State
-
-The dataflow collects runtime metrics that you can inspect in the runtime terminal.
-
-Check the `sentence-to-words` counters:
-
-```bash copy="fl"
->> show state sentence-words/sentence-to-words/metrics --table
- Key    Window  succeeded  failed
- stats  *       2          0
-```
-
-Check the `augment-count` counters:
-
-```bash copy="fl"
->> show state sentence-words/augment-count/metrics --table
- Key    Window  succeeded  failed
- stats  *       4          0
-```
-
-Congratulations! You've successfully built and run a composable dataflow! The project is available for download in [github].
-
-##### 5. Clean-up
-
-Exit the `sdf` terminal and remove the topics:
-
-```bash
-fluvio topic delete sentence
-fluvio topic delete words
-```
