 # Remotes
 
 If you want to keep a copy on a public site such as Gitlab, so others can see it, then go there and create a blank project (no readme, nothing).
-Find the address you want and add it as a remote:
+Give it the same name as the `$DIR` directory, above.

+Add this as a remote:

 Tell git you're pushing the branch "master" to the remote repo "origin": 
 
-> git push -u master origin
+```bash
+git push -u master origin

 If someone makes a change on the remote, pull it down with:
 
-> git pull

 # Branches
 
 A branch is a full copy of the project to test additional ideas.
 You can make a new branch called 'featurez' like this:
 
-> git branch *featurez*
+```bash
+git branch *featurez*
+```
 
 Have a look at all your branches:
 
-> git branch
+```bash
+git branch
+```
 
 Switch to your new branch:
 
-> git checkout *featurez*
+```bash
+git checkout *featurez*
+```
 
 And if your changes are rubbish, checkout the "master" branch again, then delete "featurez":
 
-> git branch -D *featurez*
+```bash
+git branch -D *featurez*
+```
 
 Or if it's a good branch, push it to the remote:
 
-> git push *origin* *featurez*
+```bash
+git push *origin* *featurez*
+```
 
 ## Merging
 
 Once you like the feature, merge it into the main branch.  Switch to master then merge it:
 
-> git merge *featurez*
+```bash
+git merge *featurez*
+```
 
 and delete `featurez` as you've already merged it:
 
-> git branch -d featurez
+```bash
+git branch -d featurez
