Possible outdated Docker command to update JS and CSS

[drakene]

The command below doesn't work on my Windows build for remaking CSS/JS assets. The "Home" container, in fact, shuts down after a short while of executing "docker-compose up."

However, on Gitter Yash Saravgi @Yashs911 said that the home container shutting down is normal behavior and that the command to remake CSS assets was the following:

docker-compose exec web make css  
docker-compose exec web make js  

I wanted to open an issue for this just in case there is either an problem on the wiki (which I would be willing to fix and make a pull request for if necessary) or if there is something going wrong on the Windows build. I'm still new, so it could be a mistake on my end. With that being said, Yash's solution works for me. Please let me know if I can make this issue more descriptive or neater for future reference!

Relevant url?

Steps to Reproduce

1. Get the local build up and running
2. Make some changes to CSS/JS
3. In terminal using working directory of local repo, type: docker-compose exec home npm run build-assets

Outcome

• Actual: Output in terminal of "No container found for home_1"
• Expected: Changes to CSS/JS that are reflected on local build following refresh of webpage.

Details

• Firefox
• Windows 10 Home
• Local build

Proposal & Constraints

Appropriate changes to the Docker README.md file using Yash Saravgi's suggestions.

Ah, thanks @drakene ! Yeah, that's outdated. It should be run --rm instead of exec. I opened a PR #4541. Can you test the instructions and confirm they now work?

Using the branch you created, the instructions appear to work!
