 # redismodule-rs
 
-The Rust API for Redis Modules API is based on the https://github.com/brandur/redis-cell project.
+This crate provides an idiomatic Rust API for the [Redis Modules API](https://redis.io/topics/modules-intro).
+It allows writing Redis modules in Rust, without needing to use raw pointers or unsafe code.
 
 # Running the example module
-1. install [rust and cargo](https://www.rust-lang.org/tools/install) 
-2. install redis [(mac)](https://gist.github.com/tomysmile/1b8a321e7c58499ef9f9441b2faa0aa8)
-3. run `cargo build --example hello`
-4. start a redis server with the hello module 
+
+1. [Install Rust](https://www.rust-lang.org/tools/install) 
+2. [Install Redis](https://redis.io/download), most likely using your favorite package manager (Homebrew on Mac, APT or YUM on Linux)
+3. Run `cargo build --example hello`
+4. Start a redis server with the `hello` module 
    * Linux: `redis-server --loadmodule ./target/debug/examples/libhello.so`
    * Mac: `redis-server --loadmodule ./target/debug/examples/libhello.dylib`	
-5. open a redis cli. and run `HELLO.MUL 31 11`. 
+5. Open a Redis CLI, and run `HELLO.MUL 31 11`. 
+
+# Writing your own module
+
+See the [examples](examples) directory for some sample modules.
+
+This crate tries to provide high-level wrappers around the standard Redis Modules API, while preserving the API's basic concepts.
+Therefore, following the [Redis Modules API](https://redis.io/topics/modules-intro) documentation will be mostly relevant here as well.
+
+# Redis Modules based on this crate
+
+The following are some modules that are built on this crate:
+
+- [RedisJSON](https://github.com/RedisJSON/RedisJSON)
+- [Rust API for RediSearch](https://github.com/RediSearch/redisearch-api-rs)
+
+Several member of the community have written their own modules based on this.
