Conlang is just making languages, like Tolkien did but with less intelligence behind it.
The languages are laid out in boxes like this one:
First there's the endonym, what the language is called in the language itself, and in brackets is an Anglicisation of the name, sticking as close to the pronunciation as possible.
Then there's the IPA, which uses funny symbols to help with pronunciation. The link zooms off to the IPA wiki page, but the page itself explains the pronunciation in more simple English.
Syllable structure tells you the max a single syllable can have of (C)onsonants and (V)owels. If there are other symbols there, the page itself explains it.
Last is the basic word order. All languages deviate from their general word order at times, but all have one that is around the most, which is what this section is.
Overall I want the pages to begin using simple English, to ease people in and building up their understanding of concepts. I hope you don't feel talked down to, and unfortunately it does mean reading multiple pages will mean you start back at 0 on the next page.
Something that's going to appear a lot in these pages is the idea of allophones. Very simply, it's just two different sounds that speakers of a language don't see as separate sounds.
An aspirated consonant is one that's followed by a puff of air. In English, the aspirated t, [tÊ°], in the word "top" and the unaspirated t in "stop" aren't different sounds to the vast majority of English speakers.
For an opposite example, in English the "th" in a word like "there", and the "d" in a word like "dare" are separate sounds, but to a Spanish speaker those are the same sound.
