+Low latency, data locality, and high performance are paramount.
+
+# Build n' Run
+## Build
+Install nix (and optionally direnv) and run the `shell.nix` to load all dependencies in your local environment:
+
+```bash
+nix-shell
+```
+
+Then you can build the project
+```bash
+make
+```
+
+## Run
+
+First, run the server:
+
+```bash
+# Suppress output
+./build/server > /dev/null 2>&1 &
+
+#OR
+
+# Get hit with stdout
+./build/server &
+```
+
+Then run the client:
+```bash
+./build/fastinahurry 
+```
+
+If you have direnv, run `direnv allow` and enjoy having your packages loaded automatically; no need to run `nix-shell` everytime you're in a new shell or load another `shell.nix` from another project.
