 Building the library
 --------------------
 
+Building the library has been tested with emscripten 3.1.45 and upwards. So first ensure that you 
+have activated the emscripten environment you want to use. Then run the following scripts from 
+the root folder:
 
+```bash
+./dev/em-dependencies.sh
+```
+
+This will download / checkout the dependencies and then build them. 
+
+
+```bash
+./dev/em-build.sh
+```
+
+creates the the emsccripten build of the library for the node.js environment. Resulting files are then 
+places in `./dist-node/`. If you want to use files with the web environment use 
+
+```bash
+./dev/em-web.sh
+```
+
+For all cmake switches also see the `CMakeLists.txt` file.

+Using the library
+--------------------
+
+To use the JavaScript library in your project, you just copy the files from `dist-node` to your project. 
+
+```javascript
+var createApi = require('./copasijs.js');
+var COPASI = require('./copasi.js');
+var fs = require("fs");
+
+createApi().then((Module) => {
+
+    // instantiate COPASI simulator
+    var instance = new COPASI(Module);
+
+    // check version
+    console.log('Using COPASI: ', instance.version);
+
+    // load a local file using the filesystem 
+    var data = fs.readFileSync(process.argv[2], 'utf8');
+
+    // print model structure
+    console.log(instance.loadModel(data));
+    
+    // simulate the model
+    console.log(instance.simulateEx(0, 10, 11));
+  
+});
+```
+
+for the web version it will work similarly, except that you wont use the file system module,  but rather 
+load the model file from a string.
