 GLPK.jl is a wrapper for the [GNU Linear Programming Kit library](http://www.gnu.org/software/glpk).
 It makes it possible to access nearly all of GLPK functionality from within Julia programs.
 
-See also the [GLPKMathProgInterface.jl](https://github.com/JuliaOpt/GLPKMathProgInterface.jl) package for using it with
-[MathProgBase.jl](https://github.com/JuliaOpt/MathProgBase.jl) and [JuMP.jl](https://github.com/JuliaOpt/JuMP.jl).
-
 This package is part of [the JuliaOpt project](http://www.juliaopt.org/).
 
 ## Installation

 Note that the custom binaries will not be overwritten by subsequent builds of the currently installed version of GLPK.jl. However, if GLPK.jl is updated and the update includes new BinaryProvider versions of the GLPK binaries, then the custom binaries will be overwritten by the new BinaryProvider versions.
 
-## Documentation
+## `GLPK.Optimizer`
+
+Use `GLPK.Optimizer` to create a new optimizer object:
+```julia
+using GLPK
+model = GLPK.Optimizer(tm_lim = 60.0, msg_lev = GLPK.OFF)
+```
+For JuMP, use:
+```julia
+using JuMP, GLPK
+model = Model(
+    with_optimizer(GLPK.Optimizer, tm_lim = 60.0, msg_lev = GLPK.OFF)
+)
+```
 
-- [**STABLE**][docs-stable-url] — **most recently tagged version of the documentation.**
-- [**LATEST**][docs-latest-url] — *in-development version of the documentation.*
+**Note: previous versions of `GLPK.jl` required you to choose either `GLPKSolverLP` or `GLPKSolverMIP`. This is no longer needed; just use `GLPK.Optimizer`.**

+`GLPK.jl` has a lot of pre-emptive checks to catch cases where the C API might
+throw an uninformative error. However, in benchmarks, this takes a
+non-negligible amount of time (e.g. 20% in add_constraints). At the risk of
+possibly running into an uninformative error, you can run the following after
+importing GLPK to disable these checks:
+```julia
+using GLPK
+GLPK.jl_set_preemptive_check(false)
+```
