Just made it more clear what needs to be done when following the template.
Having lines that need to be replaced rather than just added in can cause noobs confusion (going on experience in India).
Mostly grammar changes here, but there are 2 very important updates to be made:
1. Remove `EtherPress` import - it's unnecessary.
2. Change `post` in loop to `currentPost` to match the names actually used in the template.
I added the `posts.length` to `numPosts()` because it does not appear in the instructions and removed 2 `return` statements that I know will confuse people if left in, based on experience with a similar set up for the one function from DTwitter in India.
