+>Pre-condition: update/install `NodeJS` version to be >= *8.11.1*
+
 1) Install ```codecrumbs``` globally (```yarn global add codecrumbs```)
 2) Run ```codecrumbs -d project-src-dir -e project-src-dir/index.js```. Change parameters to match your project:```-d``` is *directory with source code*, ```-e``` is *entry point file* .
 3) Go to [http://localhost:2018](http://localhost:2018/#) in the browser to check it out.
 
-### CLI
-Parameter | Description | Example
---- | --- | ---
-```-d```, ```--dir``` | Relative path to project source code directory | ```-d src```
-```-e```, ```--entry``` | Relative path to project source entry point file (must be inside ```dir```) | ```-e src/app.js```
-```-x```, ```--excludeDir``` | Relative path(or paths separated by ```,```) to directories for exclusion | ```-x src/doc,src/thirdparty```

-```-n```, ```--projectName``` | Project name alias (optional, default same as ```-d``` value) | ```-n my-hello-world```
+### Configuration
+Run codecrumbs with CLI params or specify static config file `codecrumbs.config.js` (see example [here](/example-project/codecrumbs.config.js))

+> Note: current version supports single line comments only.
+
+> Hint: you can use trail id without step number (e.g. ```//cc:groupname#;test```) just to group breadcrumbs, you always can add step numbers later when you know the correct order. 
 
 ### Multi-codebase integration
 You might be interested to study connections between several codebases (sub-modules), codecrumbs supports that.
 Simply start codecrumbs multiple times (once for each codebase), it all **will be synced in one picture** inside the browser tab. To control a diagram UI - select it by clicking on it.
 
-E.g. for client-server application, go to the source directory for your server code and run `codecrumbs -e your-server-src/index.py -d your-server-src`, same for client `codecrumbs -e src-client/index.js -d src-client`. 
-> **Note:** codebases can be located wherever you want (**no** need to have them like mono-repo, etc.), simply run `codecrumbs` for directory you need.

 ## Case studies
 The tool (codecrumbs) allows us to learn, document and explain a codebase much faster. Also, with *Download & Upload* feature it becomes super easy to collect and share your "investigation results".
 
-The ultimate goal is to have many case studies hosting at [https://codecrumbs.io](https://codecrumbs.io/). **The library of projects "explained with codecrumbs", the place for collaborative learning**. More features around that coming soon, stay tuned.
