 ## The Sieve of Eratosthenes
 
-Prime numbers have many modern day applications and a long history in mathematics. Utilizing your own resources research the sieve of Eratosthenes, an algorithm for generating prime numbers. Based on your research, implement an API in `pkg/sieve/sieve.go` that allows the caller to retrieve the Nth prime number.
-Some stub code and a test suite have been provided as a convenience, however, you are encouraged to deviate from Eratosthenes's algorithm, modify the existing functions/methods or anything else that might showcase your ability provided the following requirements are satisfied.

 ### Requirements
 
-- A url to a publically accessible `git` repository (GitHub, GitLab, self-hosted, etc) of the completed exercise must be given to your coordinator at least 24 hours in advance of the technical interview
-- Interviewers must be able to clone the repository via `git clone` 
-- Interviewers must be able to execute a suite of tests via `go test ./...`
-- The go library package provides an API for retrieving the Nth prime number using 0-based indexing where the 0th prime number is 2
+- The library package provides an API for retrieving the Nth prime number using 0-based indexing where the 0th prime number is 2
+- Interviewers must be able to execute a suite of tests
+  - Go: `go test ./...`
+  - C#: `dotnet test Sieve.Tests`
+  - Javascript: `npm run test`
+- Your solution is committed to this projects `main` branch, no uncommitted changes or untracked files please.
