 Next-generation package manager for Julia. Still quite alpha. The last commit that works on 0.6 is [4bd137919](https://github.com/JuliaLang/Pkg.jl/commit/4bd1379195ce10056c26fb689f732907dd4f09fa).
 
-To install, `Pkg.clone` the `Pkg` repo itself:
+Pkg is available from the Julia nightly build or by building the Julia master branch.
 
-```jl
-Pkg.clone("https://github.com/JuliaLang/Pkg.jl.git")
-```
 
-Packages are installed under `joinpath(homedir(), ".julia", "packages")`, so they won't influence the packages that you already have installed.
+#### Using the development version of Pkg.jl
 
-```jl
-$ julia
-
-julia> using Pkg
-```
-
-This gives you a `pkg> ` REPL mode, activated by the `]` key. Currently, this supports thee operations: `add`, `rm` and `up`:

-Package operations create a `Project.toml` file that record what dependencies your project (or named global environment) has – i.e. what you've explicitly added. It also creates a `Manifest.toml` file that records the exact versions of each of those dependenices and their transitive dependencies – and the graph between them. You can load top-level dependencies via the usual `using JSON` or `import JSON` constructs in the REPL or in Julia scripts.
+If you want to develop this package do the following steps:
+- Clone the repo anywhere.
+- Remove the `uuid = ` line from the `Project.toml` file.
+- Change the current directory to the Pkg repo you just cloned.
+- `import Pkg` will now load the files in the cloned repo instead of the Pkg stdlib .
+- To test your changes, simple `include("test/runtests.jl")`.
