+> The Jira Server Plugin is part of Unleash Enterprise.
+
+With the Unleash Jira server plugin you can create new feature toggles in Unleash from a Jira issue as well as link
+existing toggles to Jira issues.
+
+The plugin also shows you current status of connected toggles.
+
+## Required access levels
+
+### Unleash
+
+You will need an Unleash Instance admin to configure an admin API token.
+
+### Jira
+
+You will need a Jira admin user.
+
+## Installation
+
+The Jira server plugin is currently not listed on the Atlassian marketplace.
+
+To get access to the Jira plugin, please reach out to sales@getunleash.io.
+
+You will receive a dedicated link that will allow you to download the Unleash Jira server plugin.
+
+Once you've downloaded the plugin artifact, you'll need to click the Manage Apps link in Jira's administration menu
+
+![Jira Manage Apps](/img/jira_server_manage_apps.png)
+
+This will take you to Atlassian's marketplace for Jira apps.
+
+From here, click the "Manage apps" link in the left-hand menu
+
+![Jira Marketplace - Manage apps](/img/jira_marketplace_manage_apps.png)
+
+Now, click "Upload app"
+
+![Jira Manage Apps - Upload App](/img/jira_upload_app.png)
+
+This will prompt you to select the plugin artifact for upload.
+
+![Jira Manage Apps - Browse](/img/jira_upload_app_dialog.png)
+
+Once you've selected your file and clicked "Upload". Jira will install the plugin, and you can move on
+to [Configuring the plugin](#configure-plugin)
+
+## Configuring plugin {#configure-plugin}
+
+After the plugin is installed. Jira's Manage Apps page will have a new menu section called "Unleash Admin" with a single
+link - "Configure servers".
+
+![Jira Manage Apps - Unleash Admin](/img/jira_server_manage_unleash_admin.png)
+
+Following the "Configure servers" link will take you to a config page where you can setup your connection(s) to Unleash
+servers. The Unleash Jira server plugin supports having a global server configured for all Jira projects, or a specific
+server configured for a specific Jira project.
+
+![Jira Manage Apps - Unleash Server Admin](/img/jira_server_manage_servers.png)
+
+Once you have configured at least one Unleash server, your users should be ready to [Use the Jira Server plugin](/integrations/jira_server_plugin_usage)
+
+### Edit existing servers
+
+In the list of known servers, each server has a connected edit button. Clicking the Edit button brings up the edit
+dialog for the server, allowing you to change the details for the selected server
+
+![Jira Manage Apps - Edit server](/img/jira_server_edit_server.png)
+
+
+### Delete (disconnect) existing servers
+
+Deleting a server from the admin interface does not actually delete the server, but it deletes Jira's knowledge of the
+server. 
+Since this is a destructive operation, our plugin will ask for confirmation that you're sure you want to do this.
+
+![Jira Manage apps - Delete server confirmation](/img/jira_server_delete_server_confirmation.png)
+
+You will not be allowed to delete a server that has toggles connected to issues, instead you'll receive a
+warning dialog telling you that you'll need to disconnect the toggles from their issues first.

+> The Jira Server Plugin is part of Unleash Enterprise.
+
+With the Unleash Jira server plugin you can create new feature toggles in Unleash from a Jira issue as well as link
+existing toggles to Jira issues.
+
+The plugin also shows you current status of connected toggles.
+
+## Using the plugin
+
+To use the plugin, you'll need to create an issue or use an existing one. Once the issue is saved and you open up the Issue panel, you'll be greeted with a button to activate the Unleash plugin for that issue.
+
+### Connecting a toggle to an issue
+
+![Jira Server - Issue panel button](/img/jira_server_issue_panel_button.png)
+
+Clicking this button opens a dialog, allowing you to either connect an existing toggle
+
+![Jira Server - Add Existing toggle](/img/jira_server_add_existing_toggle.png)
+
+or if you flip the switch that says "Use existing toggle", allows you to create a new toggle
+
+![Jira Server - Add new toggle](/img/jira_server_add_new_toggle.png)
+
+### Toggle status as part of Issue view
+
+Once you've connected at least one toggle to an issue, our plugin will list the current status of each environment for
+that toggle. If the current user is allowed to edit the issue, they can also enable or disable environments directly
+from Jira.
+
+![Jira Server - Toggle status](/img/jira_server_toggle_status.png)
+
+
+### Disconnecting toggle from Issue
+
+If a toggle is no longer relevant for your Jira Issue, you can disconnect it using the Disconnect toggle button (
+provided your user has edit rights on the issue)
+
+![Jira Server - Disconnect toggle](/img/jira_server_disconnect_toggle.png)
+
+Once you click the button, you'll need to confirm the dialog that opens up
+
+![Jira Server - Disconnect toggle dialog](/img/jira_server_disconnect_toggle_dialog.png)
+
+if confirmed, the toggle will be disconnected immediately. However, the plugin will not delete the toggle from Unleash,
+so you can still reconnect your Jira issue to the same toggle using the "Connect to existing toggle" functionality
