Then you need `git`, if you don't have that yet: https://git-scm.com/
And for the final step before we actually get started, you'll need build tools to install
the native modules used by the application. On Windows, it's easiest to open the [Command
Prompt (`cmd.exe`) as Administrator](<https://technet.microsoft.com/en-us/library/cc947813(v=ws.10).aspx>)
and run this:
### macOS
```
npm install --global --production windows-build-tools

On OSX you can install the [XCode Command-line tools](http://osxdaily.com/2014/02/12/install-command-line-tools-mac-os-x/). On Linux you'll need to take a trip to your
favorite package manager. Python 2.x and GCC are two key necessary components.
### Windows
1. **Windows 7 only:** Install Microsoft .NET Framework 4.5.1:

cd Signal-Desktop
npm install --global yarn # (only if you dont already have yarn)
npm install --global yarn # (only if you dont already have `yarn`)
yarn install --frozen-lockfile # Install and build dependencies (this will take a while)

(`View > Toggle Developer Tools`), hover over them, and press

(Windows & Linux).
Also, note that the assets loaded by the application are not necessarily the same files
you're touching. You may not see your changes until you run `yarn grunt` on the
youre touching. You may not see your changes until you run `yarn grunt` on the
command-line like you did during setup. You can make it easier on yourself by generating
the latest built assets when you change a file. Run this in its own terminal instance
while you make changes:
