 SCUDA is a GPU over IP bridge allowing GPUs on remote machines to be attached
 to CPU-only machines.
 
-## Running the server
+## Local development
+
+Make the local dev script executable
+
+```sh
+chmod +x local.sh
+```
+
+Also helpful to alias this local script in your bash profile.
 
 ```sh
-cargo run --features=disable-preload
+alias s='/home/brodey/scuda-latest/local.sh'
+```
+
+It's required to run scuda server before initiating client commands.
+
+```sh
+s server
 ```
 
 ## Running the client
 
 If the server above is running:
 
 ```sh
-cargo build --lib
-LD_PRELOAD=$(pwd)/target/debug/libscuda.so nvidia-smi
+s run
 ```
 
+The above will rebuild the client and run nvidia-smi for you.
+
 ## Installation
 
 To install SCUDA, run the server binary on the GPU host:
