+# try wren implementation
+
+This is the code to build the https://wren.io/try wasm component.
+
+### How to build
+
+- Install emscripten sdk from https://emscripten.org/
+- Make the emsdk available to your terminal/PATH 
+	- for example:
+    - source ~/dev/emsdk/emsdk_env.sh
+- Run the emmake command to build
+    - emmake make 
+
+That should be all. This builds a js + wasm file for the page.
+
+### How does the page work?
+
+The page is at `doc/site/try/template.html`.
+
+It loads `wren_try.js` which loads `wren_try.wasm`.
+The page uses emscripten API to call the `wren_compile` C function, found in `main.try.c`.
+The page hooks up printf/logging to the console for display.
+
+### Notes
+
+- The binaries land in bin/wren_try.wasm and bin/wren_try.js when building
+- The default html output from emsripten is not used, doc/site/try/template.html is
+- The wren_try.js and wren_try.wasm files are copied to doc/site/static
+- The make project is a modified version of projects/make
+- The code relies on code in test/
