README.md

+## Project
+
+The project constists of three parts:
+
+- The front-end (`./src` -> when compiled `./dist`) UI based on VueJS.
+- The back-end API (`./docker_api`) uses a very simple Python Flask server, the back-end is deployed inside a docker container with the Cheerp compiler.
+- The docker image for the front-end (`./docker_web`) that only hosts the statically build files.
+
+One part that is not finished yet is storage, and sharing code. This is the next TODO on my list.
+
+## Build
+
+For nodejs projects it can be difficult to setup a dev environment.
+It's probably important you use a new nodejs version, at least one compatible the one used: `node-v10.12.0-linux-x64`.
+
+    cd node-v10.12.0-linux-x64/bin
+    export PATH=$PATH:$PWD
+
+Please verify that it's working with:
+
+    trigen@zenbook:~/projects/cheerpweb[master]> node -v
+    v10.12.0
+    trigen@zenbook:~/projects/cheerpweb[master]> npm -v
+    6.4.1
+
+Then use the `Makefile` when developing:
+
+- `make dev` - build and start a hot swapping debug server (very convenient while developing)
+- `make api_dev` - start the API server in a docker image running on port 5000.
+
+One note on the above: also uncomment the line that uses `//localhost:5000/compile` instead of `https://cheerp.cppse.nl/api/compile` in `src/App.vue`.
+
+Other useful directives:
+
+- `make build` - build the release version (in `./dist`) of the UI (takes a while)
+- `make docker_api` - build the container that hosts the Cheerp compiler + Python Flask API server.
+- `make docker_web` - build the container that hosts the UI's static files.
+- `make prepare` - wget the node version for this project, extract and install it to `/usr/local`.
+- `make release` - there are a bunch of other Makefile directives, but better just use this one to do everything required for a release.
