Currently, the format for an entry in one of the chapter summaries is supposed to take the following form:

: **title-of-entry** : Write content of entry here.

For example, if you type

: **cyclic group** : A group [[$G$]] is cyclic if there exists [[$a\in G$]] such that [[$\langle a \rangle = G$]].

you will get

cyclic group- A group $G$ is cyclic if there exists $a\in G$ such that $\langle a \rangle = G$.

However, there are quite a few entries in the summaries that are not of this form. I'm guessing that people have found it difficult to figure out how to mimic this example. So, I've decided to make it easier on everyone, and I think things will look better, too.

Here is the new format for an entry in a chapter summary:

**title-of-entry**

Write content of entry here.

In this case, the previous example becomes

**cyclic group**

A group [[$G$]] is cyclic if there exists [[$a\in G$]] such that [[$\langle a \rangle = G$]].

which yields

cyclic group

A group $G$ is cyclic if there exists $a\in G$ such that $\langle a \rangle = G$.

I am going to go fix the current entries in the chapter summary to match the new style. I am also going to update the instructions to reflect this change.
