+# Contributing
+
+## Introduction
+
+We appreciate your interest in considering contributing to go-redis.
+Community contributions mean a lot to us.
+
+## Contributions we need
+
+You may already know how you'd like to contribute, whether it's a fix for a bug you
+encountered, or a new feature your team wants to use.
+
+If you don't know where to start, consider improving
+documentation, bug triaging, and writing tutorials are all examples of
+helpful contributions that mean less work for you.
+
+## Your First Contribution
+
+Unsure where to begin contributing? You can start by looking through
+[help-wanted
+issues](https://github.com/redis/go-redis/issues?q=is%3Aopen+is%3Aissue+label%3ahelp-wanted).
+
+Never contributed to open source before? Here are a couple of friendly
+tutorials:

+
+## Getting Started
+
+Here's how to get started with your code contribution:
+
+1.  Create your own fork of go-redis
+2.  Do the changes in your fork
+3.  If you need a development environment, run `make test`. Note: this clones and builds the latest release of [redis](https://redis.io). You also need a redis-stack-server docker, in order to run the capabilities tests. This can be started by running:
+    ```docker run -p 6379:6379 -it redis/redis-stack-server:edge```
+4.  While developing, make sure the tests pass by running `make tests`
+5.  If you like the change and think the project could use it, send a
+    pull request
+
+To see what else is part of the automation, run `invoke -l`
+
+## Testing
+
+Call `make test` to run all tests, including linters.
+
+Continuous Integration uses these same wrappers to run all of these
+tests against multiple versions of python. Feel free to test your
+changes against all the go versions supported, as declared by the
+[build.yml](./.github/workflows/build.yml) file.
+
+### Troubleshooting
+
+If you get any errors when running `make test`, make sure
+that you are using supported versions of Docker and go.
+
+## How to Report a Bug
+
+### Security Vulnerabilities
+
+**NOTE**: If you find a security vulnerability, do NOT open an issue.
+Email [Redis Open Source (<[email protected]>)](mailto:[email protected]) instead.
+
+In order to determine whether you are dealing with a security issue, ask
+yourself these two questions:
+
+-   Can I access something that's not mine, or something I shouldn't
+    have access to?
+-   Can I disable something for other people?
+
+If the answer to either of those two questions are *yes*, then you're
+probably dealing with a security issue. Note that even if you answer
+*no*  to both questions, you may still be dealing with a security
+issue, so if you're unsure, just email [us](mailto:[email protected]).
+
+### Everything Else
+
+When filing an issue, make sure to answer these five questions:
+
+1.  What version of go-redis are you using?
+2.  What version of redis are you using?
+3.  What did you do?
+4.  What did you expect to see?
+5.  What did you see instead?
+
+## Suggest a feature or enhancement
+
+If you'd like to contribute a new feature, make sure you check our
+issue list to see if someone has already proposed it. Work may already
+be underway on the feature you want or we may have rejected a
+feature like it already.
+
+If you don't see anything, open a new issue that describes the feature
+you would like and how it should work.
+
+## Code review process
+
+The core team regularly looks at pull requests. We will provide
+feedback as soon as possible. After receiving our feedback, please respond
+within two weeks. After that time, we may close your PR if it isn't
+showing any activity.
