Some of the Redis best practices content has moved

This content from this markdown file has moved a new, happier home where it can serve more people. Please check it out : https://docs.microsoft.com/azure/azure-cache-for-redis/cache-best-practices.

NOTE: Client specific guidance listed below is still valid and should still be considered. I will update this document once all content has been moved.

How do I clone a GitHub wiki?

Any GitHub wiki can be cloned by appending wiki.git to the repo url, so the clone url for the repo https://myorg/myrepo/ is: [email protected]:myorg/myrepo.wiki.git (for ssh) or https://github.com/my/myrepo.wiki.git (for https).

You make edits, and commit and push your changes, like any normal repo. This wiki repo is distinct from any clone of the project repo (the repo without wiki.get appended).

How do I add images to a wiki page?
