 ## To work on the code, either
 
 ### Use docker
+
 You need docker-compose. Simply run
 `docker-compose up` to launch the site in a docker container with livereload support. 
 
 ### Or install Jekyll locally
 
 #### Install Jekyll and Bundler gems through RubyGems
+
 `gem install jekyll bundler`
 
 #### Install dependencies
+
 `bundle install`
 
 #### Build the site local
+
 `bundle exec jekyll serve`
 
 You can now see the site at [localhost:4000](http://localhost:4000)
 
+### Or install Jekyll localy on Windows
+
+If using Ruby >=2.5 be sure to remove version numbers from dependency
+Gemfile gems and remember to also delete Gemfile.lock compiling
+Jekyll site.
+
+You will also need to recompile the gem 'eventmachine' locally.
+`gem install --platform ruby eventmachine`
+
 ## Deploy
 
 If not using Docker, it's **important** that you build the site with `JEKYLL_ENV=production bundle exec jekyll build` before deploying the contents of the `_site` directory. We're doing some debugging stuff when the project is build in the development env.
