are the docs and/or packages broken?

[https://docs.julialang.org/en/latest/manual/profile/](https://docs.julialang.org/en/latest/manual/profile/)

suggests

```julia
julia> Pkg.add("Profile")
ERROR: unknown package Profile

```

probably a simple beginner’s error, though…

I don’t see where it suggests to do a `Pkg.add`. Just use it, no need to add it, it’s included in the Julia installation.

```julia
julia> using Profile

Your link points to the docs for Julia master, i.e. the version that will eventually become 0.7, in which it will be necessary to do `using Profile`. On version 0.6 you can just do e.g. `Profile.clear()` without any imports. See [https://docs.julialang.org/en/stable/manual/profile/#Profiling-1](https://docs.julialang.org/en/stable/manual/profile/#Profiling-1)
