# Windows

## LTO Network full node

The LTO full node is comprised of a set of [Docker](https://www.docker.com/) containers. For development, use *docker compose* as orchestration tool.

### Docker Desktop

{% hint style="success" %}

1. Download [Docker Desktop for Windows](https://hub.docker.com/editions/community/docker-ce-desktop-windows).
2. Double-click `Docker Desktop for Windows Installer.exe` to run the installer.
3. Docker does not start automatically. To start it, search for `Docker` and select *Docker Desktop for Windows* in the search results.
   {% endhint %}

For more detailed instructions please read the [Installation guide in the Docker documentation](https://docs.docker.com/docker-for-windows/install/).

*Docker Desktop includes docker compose, so it's not needed to install that separately.*

### LTO full node

{% hint style="success" %}

1. Download the [docker composer configuration file](https://raw.githubusercontent.com/legalthings/lto-deepdive/master/docker/dev/docker-compose.yml) for LTO full node.
2. In PowerShell (or another terminal) run `docker-composer up`.
   {% endhint %}

## Live contracts tester

The live contract tester (`lctest`) is build on [Behat](http://behat.org/en/latest/) and runs on [PHP](https://php.net/). It requires PHP 7+ with the  *mongodb* and *yaml* PECL extension.

### PHP CLI

{% hint style="success" %}

1. Install the [Visual C++ Redistributable for Visual Studio 2015](http://www.microsoft.com/en-us/download/details.aspx?id=48145).
2. [Download PHP for Windows](https://windows.php.net/download/). Recommended is the 64-bit *Non-thread-safe* version.
3. Expand the zip file into the path `C:\PHP7`.
4. Configure PHP to run correctly on your system:
   1. In the `C:\PHP7` folder, rename the file `php.ini-development` to `php.ini`.
   2. Edit the `php.ini` file in a text editor (e.g. Notepad++, Atom, or Sublime Text).
   3. Change the following settings in the file and save the file:
      1. Uncomment the line that reads `; extension_dir = "ext"` (remove the `;` so the line is just `extension_dir = "ext"`).
      2. In the section where there are a bunch of `extension=` lines, uncomment the following lines:
         1. `extension=php_curl.dll`
         2. `extension=php_openssl.dll`
         3. `extension=php_sodium.dll`
5. Add `C:\PHP7` to your Windows system path:
   1. Open the System Control Panel.
   2. Click 'Advanced System Settings'.
   3. Click the 'Environment Variables...' button.
   4. Click on the `Path` row under 'System variables', and click 'Edit...'
   5. Click 'New' and add the row `C:\PHP7`.
   6. Click OK, then OK, then OK, and close out of the System Control Panel.
6. Open PowerShell (or another terminal emulator), and type in `php -v` to verify PHP is working.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ltonetwork.com/node/workflow-node/installation-guide/windows.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
