 ## Example usage
 
-After installing:
+1. [Install manimgl](https://3b1b.github.io/manim/getting_started/installation.html), make sure that the command `manimgl` works in your terminal
+2. Open your manim file (e.g. `scene.py`) in VSCode
+3. Place your cursor where you want to start the scene, on a line of code within the `construct` method in a scene class
+4. Run the VSCode command: `cmd+shift+p` -> `Manim Notebook: Start scene at cursor`  
+    (This command runs `manimgl scene.py NAME_OF_SCENE -se <lineNumber>` in your terminal)  
+    In the upper-right of your screen - the manim interactive video will appear.
 
-1. Open your manim `scene.py` in VSCode (replace `scene.py` with your manim file)
-2. In the attached terminal, run `manimgl scene.py NAME_OF_SCENE -se 155` (replace 155 with line number to start debugging). In the upper-right of your screen the manim interactive video should pop up
-3. Highlight the "section" you want to run (In manim, a section is a comment (`id`) followed by a block of code )
-4. Type `cmd+shift+p` "Checkpoint paste from manim-notebook" ( or default binding `cmd+' cmd+r` ). This will copy the selected code to the clipboard and send the `checkpoint_paste()` command from manim into the interactive window.
+<br />
 
-The resulting workflow looks like Grant's 🥳
+Then you can do either:
 
-[(see demo on youtube)](https://www.youtube.com/watch?v=VaNHlFh0r5E)
+- Write some comments which start with: `##`.  
+    The clickable "Preview Manim Cell" buttons will appear above each such comment.  
+    Clicking on one will run it.  
+    It is equivalent to: `cmd+shift+p` -> `Manim Notebook: Preview active Manim Cell`

+- Place your cursor on some line (or highlight several lines),  
+    `cmd+shift+p` -> `Manim Notebook: Preview selected Manim code`  
+    This will run the selected lines.
 
 
-**Default keyboard bindings**:
-- `cmd+' cmd+r` :: Run the `checkpoint_paste()` command from 3b1b's manim library on the highlighted code lines (`manim-notebook.previewSelection`)
-- `cmd+' cmd+e` :: Execute all lines of the active manim cell interactively (`manim-notebook.previewManimCell`)
+<br /><br />
 
-## Local Development
+## Keybord shortcuts
 
-Prerequisite: install `vsce` (`npm i -g vsce`)
+You can use the default keyboard shortcuts for these commands, or assign your own.  
 
-**Install locally**
+- the default shortcuts all start with `cmd+'`
+- use `cmd` or `ctrl` depending on your OS
 
-After making changes:
+All current commands are:
 
-1. Bump the version in `package.json`
-2. `vsce package` (select `y`; a `.vsix` file will be created) 
-3. `cmd+shift+p` > "Extensions: Install from VSIX" > select the `.vsix` file
-4. reload window
+- `Manim Notebook: Start scene at cursor`.  
+    Shortcut: `cmd+' cmd+s`
+- `Manim Notebook: Preview active Manim Cell`.  
+    Shortcut: `cmd+' cmd+e`
+- `Manim Notebook: Preview selected Manim code`.  
+    Shortcut: `cmd+' cmd+r`
+- `Manim Notebook: Remove all objects from scene`.  
+    Shortcut: `cmd+' cmd+c`
+- `Manim Notebook: Quit preview`.  
+    Shortcut: `cmd+' cmd+w`

-[Alternative](https://code.visualstudio.com/api/get-started/your-first-extension):
+<br /><br />
 
-- open `src/extension.ts`
-- to run the extension in a new window: `F5`  
-    (or: `cmd+shift+d` -> `Run Extension`)  
-    (or: `cmd+shift+p` -> `Debug: Start Debugging`)
-- after extension code changes: in that opened window: `cmd+shift+p` -> `Reload Window`
