First, I need to clarify if it's about the beach club or the app. The user might be looking for information on how to install the Shore app, but since they mentioned Wikipedia, it's possible they want a Wikipedia-style entry for Gandia Shore. However, installing an app usually isn't related to Wikipedia unless it's about creating a Wikipedia page for an app install guide.

I should start by researching Playa de Gandia, its history, description, facilities, tourism aspects, cultural significance, etc. Then structure the essay with sections like Introduction, Location, History, Features, Tourism, Environmental Considerations, Cultural Impact, Conclusion, and References. Ensure that it's comprehensive and academic in tone, suitable for an essay. Also, check for any possible confusion with a "Complete" version or a specific term "Completo" related to the beach's offerings.

Gandia Beach is situated in the municipality of Gandia, approximately 40 kilometers southwest of Valencia City. Its accessibility via the N332 and AP-7 highways, as well as direct train services to Gandia station, makes it a hub for both domestic and international tourists. The area’s history dates back to the Iberian and Roman periods, though Gandia itself was founded by James I of Aragon in 1261. The beach, however, gained modern prominence in the 20th century as Spain’s tourism industry expanded post-Franco era. In the 1960s and 1970s, Gandia transformed into a "sun, sea, and fun" destination, attracting visitors seeking affordable European holidays. The 1980s saw the rise of mass tourism, with the beach becoming a symbol of Spain’s Costa Blanca.

Alternatively, "Completo" could be a term used in Spain for a full menu or a set of activities. Maybe the user wants a comprehensive guide or essay about the complete experience at Gandia Beach, structured like a Wikipedia article. The mention of "install" might be a misinterpretation, perhaps "install" as a verb meaning to create a Wikipedia page.

In any case, the user likely needs a well-structured essay on Gandia Beach, possibly in the format of a Wikipedia entry. However, since the user included "install," maybe they need instructions on how to install the Shore app (though that's more a how-to guide than an essay). But since the initial query mentions "prepare essay," I should focus on the essay about Gandia Beach.
