+# Chapter 1: Getting Started
+
+_Where you will learn how to set up a development environment for Lux._
+
+---
+
+Before any coding can happen, it is necessary to set-up everything you need to become a productive Lux programmer.
+
+## Question #1: How do I write Lux code?
+
+Text editor support is a fundamental thing for any language, and Lux already covers some of that.
+The catch is that there's only support for Emacs at the moment.
+
+The plugin is called [lux-mode](https://github.com/LuxLang/lux/tree/master/lux-mode).
+
+The instructions for how to install it are at the link and it won't take much time.
+
+**Note**: If you've already installed _lux-mode_ before while using a previous version of Lux, you should install it again, as the language has changed a lot between previous versions and v0.6.
+
+## Question #2: How do I build Lux programs?
+
+Lux uses a custom-made build tool named Aedifex which is configured using a declarative Lux-based syntax.
+To install Aedifex, go to https://github.com/LuxLang/lux/tree/master/shell and download either `lux.bat` or `lux.sh` depending on whether you're on Windows or Linux/Mac.
+Also download the `aedifex.jar` file, and place it (along with either of the scripts you downloaded) somewhere in your `PATH`.
+Now, you'll have access to the `lux` command, which allows you to run Aedifex to build and test Lux projects.
+
+## Question #3: How do I use Aedifex?
+
+To find out, let's create a sample project that will have everything we need.
+
+These are the steps:
+
+1. Create a directory called `my_project`.
+1. Create a new project file at `my_project/project.lux`.
+1. Add this to the project file:
+
+```
+{#identity ["my.group" "my_project" "0.1.0-SNAPSHOT"]
+ #repositories ["https://oss.sonatype.org/content/repositories/snapshots/"
+                "https://oss.sonatype.org/service/local/staging/deploy/maven2/"]
+ 
+ #dependencies [["com.github.luxlang" "stdlib" "0.6.0" "tar"]]
+ #compiler ["com.github.luxlang" "lux-jvm" "0.6.0" "jar"]
+
+ #program "main"}
+
+## By default, Aedifex uses the "source" directory for finding your source-code.
+## The file containing our program will be my_project/source/main.lux.
+
+```
+
+1. Create `my_project/source/main.lux` and add this code to it:
+
+```
+(.module:
+  {#.doc "This will be our program's main module."}
+  [library
+   [lux #*
+    [program (#+ program:)]
+    ["." debug]
+    [control
+     ["." io]]]])
+
+(program: args
+  (io.io (debug.log! "Hello, world!")))
+
+## As you can see, this is nothing more than a very simple "Hello, world!" program to test things out.
+## Everything will be explained later in the rest of the book.
+```
+
+1. In your terminal, go to `my_project`, and execute `lux build`.
+
+When it's done, you should see a message like this:
+
+```
+...
+Compilation complete!
+Duration: +15s26ms
+[BUILD ENDED]
+```
+
+A directory named `target` will have been created, containing everything that was compiled, alongside an executable JAR file.
+
+1. Run the program with this command: `java -jar target/jvm/program.jar`
+1. Smile :)
+
+## Question #4: Where can I find documentation for Lux?
+
+A specially useful source of information is [the documentation for the standard library](https://luxlang.github.io/lux/).
+You can also explore [the Lux repository on GitHub](https://github.com/LuxLang/lux) for more information.
+
+## Question #5: Where do I talk about Lux?
+
+The place to talk about Lux is at [the Lux forum](http://luxlang.freeforums.net/).
+
+---
+
+Now, we can proceed to the actual teaching of the language!
+
+See you in the next chapter!
