This agreement is for your protection as a Contributor as well as the protection of Remotely Save and its users. It does not change your rights to use your own Contributions for any other purpose.
+
+You accept and agree to the following terms and conditions for Your Contributions (present and future) that you submit to Remotely Save. Except for the license granted herein to Remotely Save and recipients of software distributed by Remotely Save, You reserve all right, title, and interest in and to Your Contributions.
+
+1. Definitions.
+
+   "You" (or "Your") shall mean the copyright owner or legal entity authorized by the copyright owner that is making this Agreement with Remotely Save. For legal entities, the entity making a Contribution and all other entities that control, are controlled by, or are under common control with that entity are considered to be a single Contributor. For the purposes of this definition, "control" means (i) the power, direct or indirect, to cause the direction or management of such entity, whether by contract or otherwise, or (ii) ownership of fifty percent (50%) or more of the outstanding shares, or (iii) beneficial ownership of such entity.
+
+   "Contribution" shall mean any original work of authorship, including any modifications or additions to an existing work, that is intentionally submitted by You to Remotely Save for inclusion in, or documentation of, any of the products owned or managed by Remotely Save (the "Work"). For the purposes of this definition, "submitted" means any form of electronic, verbal, or written communication sent to Remotely Save or its representatives, including but not limited to communication on electronic mailing lists, source code control systems, and issue tracking systems that are managed by, or on behalf of, Remotely Save for the purpose of discussing and improving the Work, but excluding communication that is conspicuously marked or otherwise designated in writing by You as "Not a Contribution."

Subject to the terms and conditions of this Agreement, You hereby grant to Remotely Save and to recipients of software distributed by Remotely Save 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, where such license applies only to those patent claims licensable by You that are necessarily infringed by Your Contribution(s) alone or by combination of Your Contribution(s) with the Work to which such Contribution(s) was submitted. If any entity institutes patent litigation against You or any other entity (including a cross-claim or counterclaim in a lawsuit) alleging that your Contribution, or the Work to which you have contributed, constitutes direct or contributory patent infringement, then any patent licenses granted to that entity under this Agreement for that Contribution or Work shall terminate as of the date such litigation is filed.
+
+4. You represent that you are legally entitled to grant the above license. If your employer(s) has rights to intellectual property that you create that includes your Contributions, you represent that you have received permission to make Contributions on behalf of that employer, that your employer has waived such rights for your Contributions to Remotely Save, or that your employer has executed a separate Corporate CLA with Remotely Save.

You represent that Your Contribution submissions include complete details of any third-party license or other restriction (including, but not limited to, related patents and trademarks) of which you are personally aware and which are associated with any part of Your Contributions.

+
+## Links
+
+- Webdis: <https://github.com/nicolasff/webdis>
+- Redis®: <https://redis.io/>
+
+## Explanation and Background
+
+I like the Redis® software very much, and would like to experiment using it as a "file storage". It seems to be nature by using path as the key and the content as the value (Sort of..., see below).
+
+However, Redis® works by using TCP connections, and browser js cannot establish raw TCP connections. We need a HTTP gateway, to provide the HTTP api. Wedis seems to be the most famous open source one.
+
+And of course, this method should work for Redis® alternatives: Valkey, Redict, KeyDB, Dragonfly, Garnet, ...
+
+## Disclaimer
+
+This app is NOT an official Redis® Ltd / Redis® OSS / Webdis product. Redis is a registered trademark of Redis Ltd.
+
+**Never expose your Redis® or Webdis to public without security protection!!!** You are response for protecting your server.
+
+## Usage
+
+1. Install Redis®.
+2. Install Webdis.
+3. In `webdis.json`, configure the ACL for using password and username, and / or ip filters. **Never expose your Redis® or Webdis to public without security protection!!!**.
+4. Install and configure reverse proxy, firewall, https, etc. (You have to configure HTTPS correctly if you want to use it on iOS)
+5. In Remotely Save settings, enter your server address, username, password, and adjust the "base dir". Check connection.
+6. Sync!
+7. Serveral keys and values will be generated in your Redis® database:
+
+   ```
+   rs:fs:v1:${encodeURIComponent(vaultName+'/'+folderStructure+'/'+fileName)}:meta # you can HGETALL it
+   rs:fs:v1:${encodeURIComponent(vaultName+'/'+folderStructure+'/'+fileName)}:content # you can GET it
+   ```
