+{{% notice tip %}}
+NuKeeper supports Azure Devops, VSTS and TFS on premise. The same instruction apply for all these platforms!
+{{% /notice %}}
+
+NuKeeper supports intergration with Azure Devops in two ways. One of them is to use the `repo` command and the other one is through the `extension`. The benefit of the extension is that you can make a build pipeline with the extension and schedule your pipeline. This way you can automate your updating flow.
+
+## Extension
+
+The NuKeeper extension is available in the [marketplace](https://marketplace.visualstudio.com/items?itemName=nukeeper.nukeeper#overview). In order to install it you need to add it to your organisation click the `Get it free` button and follow the installation. Once that is done you can create a new pipeline and use the extension. 
+
+### Installation
+Azure Devops gives us the option to do it either in editor mode, or in yaml. 
+
+#### Yaml
+1. Add a new build pipeline and select yaml.
+1. Add the following `yml` file and adjust where necessary:
+
+    <pre>
+        <code class="language-yml">resources:
+           - repo: self #point to its own repo, change it if you don't want that
+        pool:
+            name: Hosted VS2017 # can be anything you want
+        steps:
+          - task: nukeeper.nukeeper.nukeeper.NuKeeper@0
+            displayName: NuKeeper</code><span class="copy-to-clipboard" title="Copy to clipboard"></span>
+    </pre>
+
+1. Optionally add extra arguments, The extension just call the `repo` command, so any arguments extra for your repo command can be added here.
+    <pre>
+    <code class="language-yml">resources:
+        steps:
+        - task: nukeeper.nukeeper.nukeeper.NuKeeper@0
+        displayName: NuKeeper
+        inputs:
+            arguments: '-m 3 -v d'</code><span class="copy-to-clipboard" title="Copy to clipboard"></span>
+    </pre>
+1. Go to triggers and click the <i class="fas fa-plus"></i> Add button to add your schedule. [This cannot be done in yml yet.](https://github.com/Microsoft/azure-pipelines-yaml/issues/39)
+1. Finally give the `build service user` the required *[Permissions](#permissions)* and take it for a spin by qeueing a new build!
+
+#### Editor mode
+1. Create a new build pipeline for editor mode.
+1. Select your repository and select the master branch.
+1. Add a new task to your pipeline and select NuKeeper.
+1. Optionally, click on the task and add additional arguments to the `Arguments` field. For help on the arguments checkout the [Configuration](/basics/configuration.md) page. The extension just call the `repo` command, so any arguments extra for your repo command can be added here.
+1. Go to triggers and click the <i class="fas fa-plus"></i> Add button to add your schedule.
+1. Enable your agent to access the oauth token:
+    ![Oauth checkmark](/img/oauth_checkmark.png)
+
+1. Finally give the `build service user` the required *[Permissions](#permissions)* and take it for a spin by qeueing a new build!
+
+#### Permissions
+The extensions uses the `build service user` to make a PR. By default this user is not allowed to do that. We have to give it the permissions to do so:
+
+1. Go to "Project settings" in your AzureDevops home screen.
+2. Click repositories
+3. Click Git repositories
+4. Click the build service User(the bottom one, something like: Project collection build service)
+
+Give it the following rights:
+
+- Contribute `Allow`
+- Contribute to pull requests `Allow`
+- Create branch `Allow`
+
+## Repo command
+
+The repo command works for azure-devops & vsts they same as for the other platforms. You will need a [personal access token](https://docs.microsoft.com/en-us/azure/devops/organizations/accounts/use-personal-access-tokens-to-authenticate?view=azure-devops) to use the repo command.
+
+```batch
+nukeeper repo "https://dev.azure.com/{org}/{project}/_git/{repo}/" <PAT>
+```
+
+### Additional arguments
+Add any additional arguments that are available for the repo command
+
+```batch
+nukeeper repo "https://dev.azure.com/{org}/{project}/_git/{repo}/" <PAT> -m 10
+```
+The `-m 10` tells NuKeeper that it may update 10 packages. For more parameters checkout the [Configuration](/basics/configuration.md) page.
