-## Docker
+## LASER Docker Image
 
-An image docker has been created to help you with the settings of an environment here are the step to follow :
+This image provides a convenient way to run LASER in a Docker container.
+To build the image, run the following command from the root of the LASER directory:
 
-* Open a command prompt on the root of your LASER project
-* Execute the command `docker build --tag=laser docker`
-* Once the image is built run `docker run -it laser`
+```
+docker build --tag=laser docker
+```
+Once the image is built, you can run it with the following command:
 
-A REST server on top of the embed task is under developement,
-to run it you'll have to expose a local port [CHANGEME_LOCAL_PORT] by executing the next line instead of the last command. It'll overinde the command line entrypoint of your docker container.
+```
+docker run -it laser
+```
+**Note:** If you want to expose a local port to the REST server on top of the embed task, you can do so by executing the following command instead of the last command:
 
-* `docker run -p [CHANGEME_LOCAL_PORT]:80 -it laser python app.py`
+```
+docker run -it -p [CHANGEME_LOCAL_PORT]:80 laser
+```
+This will override the command line entrypoint of the Docker container.
+
+Example:
+
+```
+docker run -it -p 8081:80 laser
+```
 
 This Flask server will serve a REST Api that can be use by calling your server with this URL :
 
-*   http://127.0.0.1:[CHANGEME_LOCAL_PORT]/vectorize?q=[YOUR_SENTENCE_URL_ENCODED]&lang=[LANGUAGE]
+```
+http://127.0.0.1:[CHANGEME_LOCAL_PORT]/vectorize?q=[YOUR_SENTENCE_URL_ENCODED]&lang=[LANGUAGE]
+```
+
+Example:
+
+```
+http://127.0.0.1:8081/vectorize?q=ki%20lo%20'orukọ%20ẹ&lang=yor
+```
+
+Sample response:
+```

+    "content": "ki lo 'orukọ ẹ",
+    "embedding": [
