+
+## Try It Out!
+
+Try it in your browser [here](https://chafey.github.io/libjxl-js/test/browser/index.html)
+
+## Building
+
+This project uses git submodules to pull in libjxl.  If developing, initialize the git submodules first:
+
+```
+> git submodule update --init --recursive
+```
+
+This project uses Docker to provide a consistent developer environment.
+
+Create docker container 'libjxljsbuild'
+
+```
+> scripts/docker-build.sh
+```
+
+Create shell inside libjxljsbuild container:
+
+```
+> scripts/docker-sh.sh
+```
+
+Install node 16 (inside docker shell):
+```
+> nvm install 16
+```
+
+To build WASM (inside docker shell):
+```
+> scripts/wasm-build.sh
+```
+
+To build native C/C++ version (inside docker shell):
+```
+> scripts/native-build.sh
+```
+
+Run performance test (inside docker shell):
+```
+> scripts/performance.sh
+```
