Команда знатоков уже готова.

In Russian, the verb to be is usually omitted in the present tense.

So:

Команда знатоков уже готова
literally looks like
Team of experts already ready

but it means
The team of experts is already ready.

Russian does use to be in other tenses:

• Команда была готова = The team was ready
• Команда будет готова = The team will be ready

Russian has no articles. A noun like команда can mean a team or the team, depending on context.

So Команда знатоков уже готова could be translated as:

• The team of experts is already ready
• A team of experts is already ready

In real context, one of those will usually sound more natural in English.

Because after a noun like команда (team), Russian often uses the second noun in the genitive plural to mean a team of ...

So:

• команда знатоков = a team of experts
• группа студентов = a group of students
• стая волков = a pack of wolves

The basic dictionary form is знаток.
Here it becomes знатоков, which is the genitive plural form.

Знаток means someone who knows a subject very well: an expert, connoisseur, or knowledgeable person.

Depending on context, it can sound:

• fairly neutral: expert
• slightly cultured/refined: connoisseur
• sometimes a bit like someone who really knows their stuff

So команда знатоков is something like a team of experts or a team of knowledgeable people.

Because команда is the grammatical subject, and команда is singular.

Even though a team contains several people, Russian treats команда as one unit, so the predicate agrees with команда, not with the people inside it.

• команда = feminine singular
• therefore готова = feminine singular

Compare:

• Команда готова = The team is ready
• Знатоки готовы = The experts are ready

If the subject were знатоки, then you would use готовы.

Because команда is a feminine noun in Russian.

Russian adjectives and short-form adjectives must agree with the noun in:

• gender
• number
• sometimes case

Here the forms are:

• masculine: готов
• feminine: готова
• neuter: готово
• plural: готовы

Since команда is feminine singular, the correct form is готова.

Готова is the short form of the adjective готовый.

In Russian, short-form adjectives are commonly used when the adjective is the main statement in the sentence:

• Команда готова = The team is ready
• Она готова = She is ready

The long form готовая is more natural when directly describing a noun:

• готовая команда = a ready/prepared team

So in this sentence, готова is the normal form because it functions like the predicate: is ready.

Уже means already or by now.

It shows that the state of being ready has already been reached.

Compare:

• Команда знатоков готова = The team of experts is ready
• Команда знатоков уже готова = The team of experts is already ready

So уже adds a sense like:

• now they are ready
• they became ready earlier than expected
• by this point, they are ready

Yes. Russian word order is more flexible than English word order, because the grammar is shown by endings as well as position.

The sentence:

Команда знатоков уже готова

is a neutral, natural order.

Other orders are possible, but they change the emphasis. For example:

• Уже готова команда знатоков = more emphasis on already ready
• Команда уже готова = natural if знатоков is understood from context

So the original order is a good standard version, but Russian can move words around for focus and style.

The stress is:

кома́нда знатоко́в уже́ готова́

If stress is difficult for you, it helps to learn the sentence with the accents marked first, because Russian stress is important and not always predictable.
