## Overview
Create, edit, and insert diagrams into your documents.
This plugin uses [draw.io](https://github.com/jgraph/drawio), a configurable diagramming/whiteboarding visualization application. draw.io is owned and developed by JGraph Ltd, a UK based software company.
The plugin is compatible with [self-hosted](https://github.com/ONLYOFFICE/DocumentServer) and [desktop](https://github.com/ONLYOFFICE/DesktopEditors) versions of ONLYOFFICE editors. It can be added to ONLYOFFICE instances manually.
## How to use
1. Open the Plugins tab and click on **draw.io**.
2. Create your own diagram in the opened window or paste one from any available resources.
3. Click "Save & exit".
4. You will see a ready diagram. If you need to make further changes to this diagram, just click on it.
5. To insert the ready diagram into your document, click the Insert button.
## How to install
Detailed instructions can be found in [ONLYOFFICE API documentation](https://api.onlyoffice.com/plugin/installation).
## User feedback and support
To ask questions and share feedback, use Issues in this repository or visit [our forum](https://forum.onlyoffice.com/c/plugins/38).

of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
