+## Easy: edit online
+
+
+## Advanced: edit in your fav code editor
+
+Any text or code editor will work for this (vi, vim, neovim, notepad++, VSCodium , VSCode, Atom, SublimeText...).
+
+- create a file `someScript.js` 
+- copy exmaple code form jscad.app
+- save the file
+- drag&drop the file to jscad.app browser window
+- put your editor and jscad.app side by side
+- edit the file, save the changes, jscad.app will automatically re-run the script
+
+A chromium based browser is required, as other browser do not allow JS to see changes to the file.
+
+## Enthusiast: a multifile project
+
+## Expert: project with package.json and workspaces for internal libs
+
+
+Bonus: if you change `main` in package.json, project will be reloaded
+and that file will be the new starting point for the project without you needing
+D&D again.

+
+
+better option is to download a nice editor that can syntax highlight JS code
+edit with the said editor (you may try VScode if it works well on your computer)
+save the fil on yor drive, and keep the openjscad window open, then drag and drop the file there
+it will render the script, and check for changes, so you continue editing it the text editor on your computer
+as soon as you save it will pick-up the changes
+... another simpler option that was made available recently on https://jscad.app/ is to copy the script text from openjscad
+
+paste there, and then just use CTRL+S it will aks the first time permission to save the file, and further saving will save the file, and render changes
+jscad.app is not official yet, but works rather well
+I personally prefer to use VSCode and drag/drop my file onto jscad.app to see it rendered there, and export in the end for 3d printing
+
+
+any editor
+drag and dropping file to openjscad or jscad.app will cause it to be given to the browser with permission to read it.
+You must use Chrome for jscad to be able to check few times a second to see if it changed
+Only Chrome can get change info and read new content ... Firefox plays dumb and will indefinitely give the initial file version, even after it chanes on your drive
