 # AbstractPPL.jl
 
-A new light-weight package, refactoring of `AbstractVarInfo` and associated APIs. The overall goals
-are creating an abstract type and minimal set of functions that will be supported all `VarInfo`
-types, e.g.
-
-- `TypedVarInfo`: VarInfo with typed model parameters, mostly for HMC,
-- `UntypedVarInfo`: VarInfo with untyped model parameters,
-- `MixedVarInfo`: VarInfo with both typed and untyped parameters. 
-
-This will likely take some time, but the hope is to unify VarInfo, improving its clarity and
-modularity.  The package will also host other future work like `NoVarInfo` for potential integration
-with non-tracing PPLs, `GraphVarInfo` for BUGS style models with statically known dependency
-structure, and generic modelling combinators (e.g. For, Switch, IID ) that are common for all PPLs.
+A new light-weight package to factor out interfaces and associated APIs for probabilistic
+programming languages (especially their modelleing languages).  The overall goals are creating an
+abstract type and minimal set of functions that will be supported all model and trace types.  Some
+other commonly used code, such as variable names, can also go here.
