+Running a Redis Server
+===
+
+StackExchange.Redis is a client library that connects to an existing redis server. So; how do you *get* a running redis server? The good news is that it isn't tricky.
+
+## Linux
+
+The main redis build targets linux, so you can simply download, make, and run redis from there; follow the instructions [here](https://redis.io/download#installation)
+
+## Windows
+
+There are multiple ways of running redis on windows:
+
+- Memurai : a fully supported, well-maintained port of redis for Windows (this is a commercial product, with a free developer version available, and free trials)
+  - previous to Memurai, MSOpenTech had a Windows port of linux, but this is no longer maintained and is now very out of date; it is not recommended, but: [here](https://www.nuget.org/packages/redis-64/)
+- WSL/WSL2 : on Windows 10, you can run redis for linux in the Windows Subsystem for Linux; note, however, that WSL may have some significant performance implications, and WSL2 appears as a *different* machine (not the local machine), due to running as a VM
+
+## Docker
+
+If you are happy to run redis in a container, [an image is available on Docker Hub](https://hub.docker.com/_/redis/)
+
+## Cloud
+
+If you don't want to run your own redis servers, multiple cloud offerings are available, including
+
+- RedisLabs
+- Azure Redis Cache
+- AWS ElastiCache for Redis
