+# R Bindings
+
+This package demonstrates how to call Rust functions from R using extendr.
+I (@CarolineMorton) have not yet implemented this with our Codelist library 
+but rather with a simple "hello world" function.
+
+## Prerequisites
+
+- Install R (version 4.0 or higher recommended)
+    - macOS: `brew install r`
+
+#### Notes
+- My R installation took a long time to complete, so be patient here. It seems like it was broken 
+because for some reason installing R also means it installs the latest version of Python, Pytorch and
+a bunch of other things. I'm not super familiar with R or why it does this but 🤷‍♀️ it might just be a
+me problem.
+- I think you need to have Xcode installed on macOS to get the C bridge to work.
+- I had to add R to my path before I could get into the R console via the terminal:
+```bash
+R
+```
+- An alternative is to use RStudio, which is a popular IDE for R.
+- You can exit the R console with `q()`. You then get this:
+```bash
+Save workspace image? [y/n/c]: 
+```
+which i said no to.
+
+## Building and Installing
+
+1. First build the Rust library:
+```bash
+cd r
+cargo build --release
+```
+
+This will create a shared library in `target/release/libcodelist.dylib` (macOS) or `target/release/libcodelist.so` (Linux).
+
+2. Open R with the terminal command `R`
+and install required packages. If you get an error message when running this, you may also need to install package dependencies for `devtools` first if not already installed:
+```r
+install.packages("devtools") 
+install.packages("rextendr")
+```
+
+I picked `64` as the mirror I wanted to use. 
+
+
+3. Build and load the package:
+```r
+rextendr::document()
+devtools::document()
+devtools::load_all()
+```
+
+4. Test that it works:
+```r
+hello()
+```
+
+## Installing Permanently
+
+To install the package permanently:
+
+```r
+devtools::build()
+devtools::install()
+```
+
+After installation, you can use it like any other R package:
+
+```r
+library(codelist)
+hello()
+```
