# A Holochain Developer Tutorial - Part 2 [![hackmd-github-sync-badge](https://hackmd.io/6XqdY1-bTCS4usegLjoWCg/badge)](https://hackmd.io/6XqdY1-bTCS4usegLjoWCg) Sending and receiving data to and from the conductor and saving entries on the source chain. _Coming ... at some point ..._ I'm taking a bit of time off from this tutorial while I build some hApps. It has served my learning well so far. So well that I think I'm ready for some time in [the gym](https://holochain-gym.github.io/) and building some things. I'm looking forward to coming back to this when I'm more equipped to ensure its usefulness.

A Holochain Developer Tutorial - Part 1

DRAFT Where we're going We will be building a complete Holochain app that includes testing and a user interface. We'll start with a simple zome, add the smallest test we can write, and call the zome from a simple web client. Once we have something simple that operates across the full stack, we'll add more complexity in future parts of this tutorial by adding more features to the app. This will allow us to learn different aspects of Holochain as we need the functionality. As far as what we're building ... I haven't decided yet. We're just going to start. Perhaps we'll identify the path we're on once we start walking. Setting things up

A Holochain Developer Tutorial

This tutorial intends to be a step-by-step walk-through of building a Holochain application (hApp). The app's features are chosen specifically to highlight capabilities of the Holochain platform and are implemented in an order that should build on previous concepts. This tutorial doesn't expect any prior knowledge of Holochain or the Rust language. It will explain concepts and provide links to learn more as they arrive on our journey. However, it does assume you are a professional developer, competent in at least one language/platform. This tutorial is written with the expectation you are following along with it. If you are only interested in doing the hands-on parts and aren't interested in a deeper understanding of the concepts, just follow the instructions. All additional concepts and explanations will be clearly marked. This tutorial is maintained on GitHub (along with the code) and available for easy reading and collaboration on HackMD. If you have any questions or improvement recommendations, please leave a comment, rather than creating an issue on GitHub. Part 1: A thin layer from front to back This section is basically the fullstack "Hello World" example. It has you build a function in a zome, package it into DNA, bundle the DNA into a hApp, make it available from a local conductor and invoke it from a simple web frontend.
