To make your writing flow better, try using a conjunction to combine those two short sentences.
A coordinating conjunction joins elements of equal syntactic weight, whereas a subordinating one introduces a dependent clause that relies on the main sentence.
From Old French conjonction, from Latin coniūnctiō (“joining”), from coniungere (“to join”).
Outside of grammar, the noun frequently appears in the phrase 'in conjunction with', meaning together or at the same time.
