+## Dynamic worker pools
+
+Daggers default scheduler supports modifying the worker pool while the 
+scheduler is running. This is done by modifying the `Processor`s of the 
+`Context` supplied to the scheduler at initialization using 
+`addprocs!(ctx, ps)` and `rmprocs(ctx, ps)` where `ps` can be `Processors` or
+ just process ids. 
+
+An example of when this is useful is in HPC environments where individual 
+jobs to start up workers are queued so that not all workers are guaranteed to 
+be available at the same time.
+
+New workers will typically be assigned new tasks as soon as the scheduler
+sees them. Removed workers will finish all their assigned tasks but will not
+be assigned any new tasks. Note that this makes it difficult to determine when 
+a worker is no longer in use by Dagger.
+
+Example:
+
+```julia
+using Distributed
+
+ps1 = addprocs(2, exeflags="--project");
+@everywhere using Distributed, Dagger
+
+# Dummy task to wait for 0.5 seconds and then return the id of the worker
+ts = delayed(vcat)((delayed(i -> (sleep(0.5); myid()))(i) for i in 1:20)...);
+
+ctx = Context();
+# Scheduler is blocking, so we need a new task to add workers while it runs
+job = @async collect(ctx, ts); 
+
+# Lets fire up some new workers
+ps2 = addprocs(2, exeflags="--project");
+@everywhere using Distributed, Dagger
+# New workers are not available until we do this
+addprocs!(ctx, ps2)
+
+# Lets hope the job didn't complete before workers were added :)
+fetch(job) |> unique
+
+# and cleanup after ourselves...
+workers() |> rmprocs
+```
