 - For practice exercises, `instructions.md` come from the [problem specifications](https://github.com/exercism/problem-specifications) repository. They cannot be changed without updating them in that repository first. If Elixir-specific changes are necessary, they can be appended to the instructions by creating a `instructions.append.md` file.

 - Each practice exercise test file should have a `test_helper.exs` with code like the following at the top of the file.
   This allows the tests to be run on CI and configures tests to be skipped with the `:pending` flag.

 [_Atoms_][atom] are internally represented by an integer in a lookup table, which are set automatically. That makes comparing atoms faster than comparing strings. It is not possible to change this internal value. It is generally considered to be an [anti-pattern][anti-pattern] to dynamically create atoms from user supplied input. The runtime only has space for a limited number of atoms, generating new atoms at runtime could fail if the atom table is full.
