+The code of conduct is described in [`CODE_OF_CONDUCT.md`](CODE_OF_CONDUCT.md)
 
-## Bug Reports
+## Contributor License Agreement ("CLA")
-[bug-reports]: #bug-reports
-- **Ensure the bug has not already been reported** - this can be done with a quick search of the [existing open issues](https://github.com/rust-rocksdb/rust-rocksdb/issues?q=is%3Aissue+is%3Aopen+).
-- **Ensure the bug applies to the Rust wrapper, and not the underlying library** - bugs in the RocksDB library should be [reported upstream](https://github.com/facebook/rocksdb/issues).
-- When [creating an issue](https://github.com/rust-rocksdb/rust-rocksdb/issues/new) please try to:
-    - **Use a clear and descriptive title** to identify the issue
-    - **Provide enough context** to acurately summarize the issue. Not every issue will need detailed steps to recreate, example code, stack traces, etc. - use your own judgment on what information would be helpful to anyone working on the issue. It's easier for someone to skim over too much context, than stop and wait for a response when context is missing.
 
-## Feature Requests
+In order to accept your pull request, we need you to submit a CLA. You

+only need to do this once, so if you've done this for another Facebook
-Feature requests will primarily come in the form of ergonomics involving the Rust language, or in bringing the wrapper into parity with the library's API. Please create an issue with any relevant information.
+open source project, you're good to go. If you are submitting a pull
+request for the first time, just let us know that you have completed
+the CLA and we can cross-check with your GitHub username.
 
-## Documentation
+Complete your CLA here: <https://code.facebook.com/cla>
-[documentation]: #documentation
-Much of the documentation should mirror or reference the library's [documentation](https://github.com/facebook/rocksdb/wiki). If the wrapper or its exposed functions are missing documentation or contain inaccurate information please submit a pull request.
-
-## Discussion
-[discussion]: #discussion
-Discussion around design and development of the wrapper primarily occurs within issues and pull requests. Don't be afraid to participate if you have questions, concerns, insight, or advice.

-## Pull Requests
-[pull-requests]: #pull-requests
-Pull requests are welcome, and when contributing code, the author agrees to do so under the project's [licensing](https://github.com/rust-rocksdb/rust-rocksdb/blob/master/LICENSE) - Apache 2.0 as of the time of this writing. The maintainers greatly appreciate PRs that follow open-source contribution best practices:
-1. Fork this repository to your personal GitHub account.
-1. Create a branch that includes your changes, **keep changes isolated and granular**.
-1. Include any relevant documentation and/or tests. Write [documentation tests](https://doc.rust-lang.org/rustdoc/documentation-tests.html) when relevant.
-1. Apply `cargo fmt` to ensure consistent formatting.
-1. [Create a pull request](https://help.github.com/en/articles/about-pull-requests) against this repository.
-
-For pull requests that would benefit from discussion and review earlier in the development process, use a [Draft Pull Request](https://help.github.com/en/articles/about-pull-requests#draft-pull-requests).

-      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

-      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

-Maintainers agree to operate under this set of guidelines:
-
-#### Authority
-
-Maintainers are trusted to close issues, merge pull requests, and publish crates to cargo.
-
-#### Categories of Work
-
-0. Minor
-    * updating the changelog
-    * requires no approval
-1. Normal
-    * librocksdb-sys updates
-    * API tracking code in the rocksdb crate that does not change control flow
-    * breaking changes due to removed functionality in rocksdb
-    * require 1 approval from another maintainer. if no maintainer is able to be reached for 2 weeks, then progress may be made anyway
-    * patch (and post-1.0, minor) releases to crates.io that contain only the above work
-2. Major
-    * breaking API changes that are not direct consequences of underlying rocksdb changes
-    * refactoring, which should generally only be done for clearly functional reasons like to aid in the completion of a specific task
-    * require consensus among all maintainers unless 2 weeks have gone by without full participation
-    * if 2 weeks have gone by after seeking feedback, and at least one other maintainer has participated, and all participating maintainers are in agreement, then progress may be made anyway
-    * if action is absolutely urgent, an organization owner may act as a tiebreaker if specifically requested to do so and they agree that making a controversial decision is worth the risk. This should hopefully never occur.
-  
-If any maintainer thinks an issue is major, it is major.
-
-#### Changelog Maintenance
-
-* If you are the one who merges a PR that includes an externally-visible change, please describe the change in the changelog and merge it in.
-
-#### Releasing, Publishing
-
-* Releases adhere to [semver](https://semver.org/)
-* To cut a release, an issue should be opened for it and reach the required approval based on the above `Categories of Work` section above
-* When progress is possible, the issue may be closed and the proposer may publish to crates.io. This is controlled by those in the [crate publishers organization-level team](https://github.com/orgs/rust-rocksdb/teams/crate-publishers).
-* Releases should have an associated tag pushed to this repo. I recommend doing this after the publish to crates.io succeeds to prevent any mishaps around pushing a tag for something that can't actually be published.
-* The changelog serves as a sort of logical staging area for releases
-* If a breaking API change happens, and the changelog has not advanced to a new major version, we roll the changelog to a new major version and open an issue to release the previous patch (and post-1.0, minor) version.
-* Before rolling to a new major version, it would be nice to release a non-breaking point release to let current users silently take advantage of any improvements
-
-#### Becoming a Maintainer
-
-* If you have a history of participation in this repo, agree to these rules, and wish to take on maintainership responsibilities, you may open an issue. If an owner agrees, they will add you to the maintainer group and the crate publishers team.

+RocksDB is developed and maintained by Facebook Database Engineering Team.
+It is built on earlier work on [LevelDB](https://github.com/google/leveldb) by Sanjay Ghemawat (sanjay@google.com)
+and Jeff Dean (jeff@google.com)
 
-## Requirements
+This code is a library that forms the core building block for a fast
+key-value server, especially suited for storing data on flash drives.
+It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs
+between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF)
+and Space-Amplification-Factor (SAF). It has multi-threaded compactions,
+making it especially suitable for storing multiple terabytes of data in a
+single database.

-[LZ4](https://github.com/lz4/lz4), [Zstd](https://github.com/facebook/zstd),
-[Zlib](https://zlib.net), and [Bzip2](http://www.bzip.org) compression
-is enabled through crate features. If support for all of these compression
-algorithms is not needed, default features can be disabled and specific
-compression algorithms can be enabled. For example, to enable only LZ4
-compression support, make these changes to your Cargo.toml:
-
-```
-[dependencies.rocksdb]
-default-features = false
-features = ["lz4"]
-```

-## Multithreaded ColumnFamily alternation
-
-The underlying RocksDB does allow column families to be created and dropped
-from multiple threads concurrently. But this crate doesn't allow it by default
-for compatibility. If you need to modify column families concurrently, enable
-crate feature called `multi-threaded-cf`, which makes this binding's
-data structures to use RwLock by default. Alternatively, you can directly create
-`DBWithThreadMode<MultiThreaded>` without enabling the crate feature.
