+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          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.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.

+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      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
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+# Tinode Web
 
+## Briefing
+
+Single-page web chat application for [Tinode](https://github.com/tinode/chat/). The app is built on
+[React](https://reactjs.org/). The [Tinode javascript SDK](https://github.com/tinode/tinode-js/) has no external dependencies.
+Overall, it's a lot like open source WhatsApp or Telegram web apps.
+
+Although the app is generally usable, keep in mind that this is work in progress. Some bugs probably exist, some features are missing. The app was tested in the latest Chrome & Firefox only. NPM package is [available](https://www.npmjs.com/package/tinode-webapp).
+
+Try possibly newer or older version live at https://sandbox.tinode.co/.
+
+<a href="https://web.tinode.co/"><img src="web-app.svg" height=36></a>
+
+For demo access and other instructions [see here](https://github.com/tinode/chat/#demosandbox).
+
+## Installing and running
+
+This is _NOT_ a standalone app, this is just a frontend, a client. It requires a [backend](https://github.com/tinode/chat/). See [installation instructions](https://github.com/tinode/chat/blob/master/INSTALL.md). See instructions for [enabling push notifications](push.md).
+
+## Getting support
+
+* Read [client-side](http://tinode.github.io/js-api/) and [server-side](https://github.com/tinode/chat/blob/master/docs/API.md) API documentation.
+* For support, general questions, discussions post to [https://groups.google.com/d/forum/tinode](https://groups.google.com/d/forum/tinode).
+* For bugs and feature requests [open an issue](https://github.com/tinode/webchat/issues/new).
+* Use https://tinode.co/contact for commercial inquiries.
+
+## Helping out
+
+* If you appreciate our work, please help spread the word! Sharing on Reddit, HN, and other communities helps more than you think.
+* Consider buying paid support: https://tinode.co/support.html
+* If you are a software developer, send us your pull requests with bug fixes and new features.
+* If you use the app and discover bugs or missing features, let us know by filing bug reports and feature requests. Vote for existing [feature requests](https://github.com/tinode/chat/issues?q=is%3Aissue+is%3Aopen+sort%3Areactions-%2B1-desc+label%3A%22feature+request%22) you find most valuable.
+* If you speak a language other than English, [translate](https://github.com/tinode/chat/blob/devel/docs/translations.md#webapp) the apps into your language. You may also review and improve existing translations.
+* If you are a UI/UX expert, help us polish the app UI.
+* Use it: install it for your colleagues or friends at work or at home.
+
+## Internationalization
+
+The app is fully internationalized using [React-Intl](https://github.com/formatjs/react-intl). The UI language is selected automatically from the language specified by the browser. A specific language can be forced by adding `#?hl=XX` parameter to the URL when starting the app, e.g. https://web.tinode.co/#?hl=fr.
+
+The app is currently available in the following languages:
+ * English - default
+ * Arabic
+ * Chinese simplified
+ * Chinese traditional
+ * French
+ * German
+ * Italian
+ * Korean
+ * Romanian
+ * Russian
+ * Spanish
+ * Thai
+ * Ukrainian
+
+More translations are welcome. See [instructions](https://github.com/tinode/chat/blob/devel/docs/translations.md#webapp).
+
+
+## Not done yet
+
+* End-to-End encryption.
+* Emoji support is weak.
+* Mentions, hashtags.
+* Previews not generated for links and docs.
+* Location and contact sharing.
+* Recording video messages.
+
+## Other
+
+* Demo avatars and some other graphics are from https://www.pexels.com/ under [CC0 license](https://www.pexels.com/photo-license/).
+* Background patterns from http://subtlepatterns.com/, commercial and non-commercial use allowed with attribution.
+* [Fonts](https://fonts.google.com/) and [icons](https://google.github.io/material-design-icons/#icon-font-for-the-web) from Google under [license](https://developers.google.com/terms) which permits commercial and non-commercial use.
+* Push notifications built with https://firebase.google.com/.

+# Push notifications
+
+If you want to use the app with your own server and want web push notification to work you have to set them up:
+
+* Register at https://firebase.google.com/, set up the project if you have not done so already.
+* Follow instructions to create a web application https://support.google.com/firebase/answer/9326094 in your project.
+* Follow instructions at https://support.google.com/firebase/answer/7015592 to get a Firebase configuration object ("Firebase SDK snippet").
+* Locate `firebase-init.js` in the root folder of your copy of TinodeWeb app. Copy-paste the following keys from the configuration object to `firebase-init.js`: `apiKey`, `messagingSenderId`, `projectId`, `appId` (you may copy all keys).
+* Copy `Web Push certificate` (Project Settings -> Cloud Messaging -> Web configuration -> Web Push certificates) to `messagingVapidKey` field in `firebase-init.js`.
+* Double check that `firebase-init.js` contains the following keys: `apiKey`, `messagingSenderId`, `projectId`, `appId`, `messagingVapidKey`. The file may contain other optional keys.
+* Copy Google-provided server key to `tinode.conf`, see details [here](https://github.com/tinode/chat/blob/master/docs/faq.md#q-how-to-setup-fcm-push-notifications).
