 Thunderbird is a powerful and customizable open source email client with lots of users. It is based on the same platform that Firefox uses.
 
 ## Getting Started
 This README will try and give you the basics that you need to get started, more comprehensive documentation is available on the [Thunderbird Developer Website](https://developer.thunderbird.net).
 
 ### Mozilla Code Base
 Thunderbird is built on the Mozilla platform, the same base that Firefox is built from. As such the two projects share a lot of code and much of the documentation for one will apply, in many ways, to the other.
 
-In order to be able to build Thunderbird - you will need the mozilla-central repository as well as the comm-central repository (where this README lives). Check out our [Getting Started documentation](https://developer.thunderbird.net/the-basics/getting-started) for instructions on how and where to get the source code.

 ### mozilla-central vs. comm-central
 
 The mozilla-central repostitory contains the Firefox codebase and all of the platform code. The comm-central repository is added as a subdirectory "comm/" under mozilla-central. This contains the code for Thunderbird.
 
 ## Building Thunderbird

 ### Build Configuration
 
 To build Thunderbird, you need to create a file named `mozconfig` (can also be `.mozconfig`) to the root directory of the mozilla-central checkout that contains the option `comm/mail` enabled. You can create a file with this line by doing this in the root source directory:
 
 ```text
 echo 'ac_add_options --enable-application=comm/mail' > mozconfig
 ```
