+# Set up this project for local development
+
+This project requires Ruby to run so you'll need to install it.  
+With Ubuntu, this will be:
+
+```bash
+sudo apt install ruby ruby-dev
+```
+
+Then you'll need to install the dependencies.  
+To avoid permission error and not use sudo for the next commands, you can install the gems in your home directory:
+
+```bash
+export OD_GEMS=$HOME/.odgems
+export GEM_HOME=$OD_GEMS/ruby/2.7.0
+export PATH=$OD_GEMS/bin:$PATH
+bundle config set --local path "$OD_GEMS"
+bundle install
+```
+
+And run locally overriding the `host` config value:
+
+```bash
+bundle exec jekyll serve --watch --incremental --trace --host=localhost
+```
