-## How to use JShellWrapper alone
-### From command line
-- Run BuildJShellWrapper.bat/.sh to compile the wrapper and package it into a jar
-- Run java -DevalTimeoutSeconds=15 -jar ./JShellWrapper/out/JShellWrapper.jar
+# Structure of the project
+There are two projects, JShellAPI and JShellWrapper
+JShellAPI is a REST API, and whenever some code is received, it will create a session, by creating a docker container, which will run JShellWrapper inside and then execute the given code in JShellWrapper.
+
+## How to use JShellWrapper alone in local
 ### From IntelliJ
-- Open IntelliJ on the project JShellWrapper
 - Go in Run → Run... → Edit Configurations → create a configuration
-- Select the main class, the jdk, etc, click on modify options, and check VM options, then add -DevalTimeoutSeconds=15 in the VM options
+- Select the command `JShellWrapper:run`
+- Click on modify options, and check `VM options`
+- Then add `evalTimeoutSeconds=15;sysOutCharLimit=1024` in the VM options
 - Press the run button

+## How to use JShellAPI
 ### From the console
-- Run BuildJShellWrapper.bat/.sh to compile the wrapper and package it into a jar
-- Run BuildImage.bat/.sh to build the image
-- Run ./gradlew bootRun
+- Launch Docker
+- Run `./gradlew :JShellWrapper:jibDockerBuild` to build the image
+- Run `./gradlew bootRun`
 ### How to build and run from IntelliJ
-- Run BuildJShellWrapper.bat/.sh
-- Open IntelliJ on JShellAPI
-- Run the main class
-### using IntelliJ instead of BuildJShellWrapper script
-- Open IntelliJ on the project JShellWrapper
-- Go in build → Build Artifacts... → Build
-- The jar should be located directly under JShellWrapper/out
+- Launch Docker
+- Run `JShellWrapper:jibDockerBuild` to build the image
+- Run `bootRun`
+
+# How to build JShellAPI in and run it in Docker
+- Launch Docker
+- Run `jibDockerBuild` to create the image
+- Create a folder
+- Create `docker-compose.yml`:
+ ```yml
+services:
+  jshell-backend-master:
+    image: "togetherjava.org:5001/togetherjava/jshellbackend:master"
+    command: ["--spring.config.location=file:///home/backend/config/application.properties"]
+    restart: always
+    ports:
+      - 54321:8080
+      - 5005:5005
+    environment:
+      JAVA_TOOL_OPTIONS: "-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005"
+    volumes:
+      - /var/run/docker.sock:/var/run/docker.sock
+      - ./docker-config.json:/root/.docker/config.json
+      - ./config:/home/backend/config
+    networks:
+      - jshell-backend
+
+networks:
+  jshell-backend:
+    external: true
+    name: develop-bot
+  ```
+- Optionaly, create `config/application.properties` where you can put custom config (see the actual [application.properties](JShellAPI/src/main/resources/application.properties))
+- If you don't create it, delete the `command: ["--spring.config.location=file:///home/backend/config/application.properties"]` line in the `docker-compose.yml`
+- Run `docker compose build` or `docker-compose build` in the folder, depending of your version of Docker.
+- Run `docker compose start` or `docker-compose start` in the folder, depending of your version of Docker.
