 # scratch-poppy
-### Scratch-poppy is a Scratch 3 extension for Poppy robots
+Scratch-poppy is a Scratch 3 extension for [Poppy robots](https://github.com/poppy-project).  
 
-## Getting started
+## :inbox_tray: Installation
 
-### Scratch VM and Scratch GUI installation
-
-This requires you to have **Git** and **Node.js** installed.
-First, you will have to clone **scratch-vm** and **scratch-gui** and to link both. For this, open a Command Prompt or Terminal in your development environment and follow the next steps:
-
-    git clone https://github.com/LLK/scratch-gui
-    git clone https://github.com/LLK/scratch-vm
-    cd scratch-vm
-    curl -sL https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh -o install_nvm.sh
-    bash install_nvm.sh
-    source ~/.profile
-    rm install_nvm.sh
-    nvm install 10.21.0
-    nvm use 10.21.0
-    npm install
-    npm link
-    cd ../scratch-gui
-    npm install
-    npm link scratch-vm
-
-
-### Scratch Poppy installation
-
-Now, you can clone this repository in the same development environment. For the installation you just have to execute the following lines to copy folders and some extension's additions at the right place:
-
-    git clone https://github.com/poppy-project/scratch-poppy
-    cd scratch-poppy
-    bash install.sh
+### :page_facing_up: Scripted installation
 
+Requirements : [git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git "sudo apt install git-all"), [node](https://nodejs.org/en/download/package-manager/ "sudo apt install nodejs"), [zip](https://linux.die.net/man/1/zip "sudo apt install zip"),
 
+#### Install scratch files & poppy's extension
+We need [scratch-vm](https://github.com/LLK/scratch-vm "GitHub scratch-vm repository") and [scratch-gui](https://github.com/LLK/scratch-gui "GitHub scratch-gui repository") repositories to create our application, we download and install them with **install-scratch-files.sh** script. Then, we install our Poppy extension with **install-extension.sh** script.
+```bash
+bash install-scratch-files.sh
+bash install-extension.sh
+```
 
-### Launching and editing
+#### Exporting application
+To use scratch with Poppy without having to use node on the raspberry, we export static files we just built as an archive. The archive will be uploaded as a release of poppy-scratch repository, and can be downloaded if the user wants to use Scratch.
+```bash
+bash export-scratch.sh
+```
 
-Now it is possible to launch scratch in the repository **scratch-gui** with: 
-    
-    cd scratch-gui
-    npm start
+### :keyboard: Manual installation
 
-Then go to http://localhost:8601/ in your web browser.
-Select the **Poppy extension** in the extension menu (with the button at the bottom left corner).
+#### Scratch VM and Scratch GUI installation
 
-If you want to edit blocks, the code are now situated  at this path: `scratch-vm/src/extensions/scratch3_poppy/index.js`. You can find more informations to create a block here: https://github.com/LLK/scratch-vm/blob/develop/docs/extensions.md
-
-### TODO:
-
-* To implement the button "sequentially" and "play senquentially". These buttons allow to play different actions, for the first one, and moves, for the second, one after the other.
-
-* To implement the "wait" option in the "setMotorsGoTo" button to wait until a motor reaches its position before moving a second motor.
-
-* To add the different lists ("all motors", "all motors position", "all recorded moves" ...) directly in scratch (in the index.js file or in the scratch project)
-
-See the `Advanced.sb3` scratch project to see the last two points.

+First, you will have to clone **scratch-vm** and **scratch-gui** and to link both. For this, open a Command Prompt or Terminal in your development environment and follow the next steps:
+```bash
+git clone https://github.com/LLK/scratch-gui
+git clone https://github.com/LLK/scratch-vm
+cd scratch-vm
+curl -sL https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh -o install_nvm.sh
+bash install_nvm.sh
+source ~/.profile
+rm install_nvm.sh
+export NVM_DIR="$HOME/.nvm"
+[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # loads nvm without reopening a terminal
+nvm install 10.21.0
+nvm use 10.21.0
+npm install
+npm link
+cd ../scratch-gui
+npm install
+npm link scratch-vm
+```
+
+Then you will need to install Poppy's extension in Scratch files. In **scratch-poppy** run:
+```bash
+bash install-extension.sh
+```
+
+#### Building application
+To build the application, go to **scratch-gui** folder and run :
+```bash
+sudo npm run build
+```
+
+#### Exporting application
+To use scratch with Poppy without having to use node on the raspberry, we export static files we just built as an archive. The archive will be uploaded as a release of poppy-scratch repository, and can be downloaded if the user wants to use Scratch.
+To export the application as a zip archive, we need to rename the build folder as **scratch-application** in **scratch-gui**.
+```bash
+mv build scratch-application
+```
+Then zip it:
+```bash
+zip -r scratch-application.zip scratch-application
+```
+
+## :memo: Edit Poppy's Extension
+
+You can add more blocks by modifying **scratch_vm_files/scratch3_poppy** files.
+You can find information to create a block here: https://github.com/LLK/scratch-vm/blob/develop/docs/extensions.md
+
+To see and test your blocks run the script install_extension.sh and then go to **scratch-gui** folder. You can either:
+- run a server that will auto reload Scratch server each time you run the install_extension.sh script.
+For this, run:
+  ```bash
+  sudo npm start
+  ```
+  Then go to http://localhost:8601/ in your web browser.
+  Make sure to install the **Poppy extension** in the extension menu (button in the bottom left corner).
+  
+
+- build the static files and open index.html with your browser. You will have to run those steps each time you run  install_extention.sh script.
+  ```bash
+  sudo npm run build
+  cd build
+  firefox index.html  # Or google-chrome, chromium-browser, ...
+  ```
+
+## :scroll: Todo
+
+* Implement the button "sequentially" and "play sequentially". These buttons allow playing different actions, for the first one, and moves, for the second, one after the other.
