### Initializing a new Client

<RefSubLayout.EducationRow>
  <RefSubLayout.Details>

Initializing a new client is pretty straightforward. Find your project url and public key from the
admin panel and pass it into your client initialization function.

`supabase-csharp` is heavily dependent on Models deriving from `BaseModel`. To interact with the API, one must have the associated model (see example) specified.

Leverage `Table`, `PrimaryKey`, and `Column` attributes to specify names of classes/properties that are different from their C# Versions.
