 ## Manipulating `EpiAware` model specifications
 
-### Specifying models which are components
+### Modular model construction
 
-#### Modular model construction
+One of the key features of `EpiAware` is the ability to specify models as components of a larger model.
+This is useful for specifying models that are shared across multiple `EpiProblems` or for specifying models that are used in multiple methods.
+You can see an examples of this approach in our [showcases](@ref showcase).
 
-#### Remaking models
+### Remaking models
+
+An alternative to modular model construction is to remake models with different parameters. This can be useful for comparing models with different parameters or for comparing models with different priors.
+Whilst we don't have a built in function for this, we recommend the `Accessors.jl` package for this purpose.
+For examples of how to use this package see the [documentation](https://juliaobjects.github.io/Accessors.jl/stable/getting_started/).
 
 ## Working with `Turing.jl` models
 
-### Conditioning and fixing models
+### `DynamicPPL.jl`](https://github.com/TuringLang/DynamicPPL.jl)
+
+Whilst `Turing.jl` is the front end of the `Turing.jl` ecosystem, it is not the only package that can be used to work with `Turing.jl` models. [`DynamicPPL.jl`](https://github.com/TuringLang/DynamicPPL.jl) is the part of the ecosytem that deals with defining, running, and manipulating models.
+
+#### Conditioning and deconditioning models
+
+`DynamicPPL` supports the `condition` (alased with `|`) to fix values as known *observations* in the model (i.e fixing values on the left hand side of `~` definitions).
+This is useful for fixing parameters to known values or for conditioning the model on data.
+The `decondition` function can be used to remove these conditions.
+Internally this is what [`apply_method(::EpiProblem, ...)`](https://cdcgov.github.io/Rt-without-renewal/dev/lib/EpiAwareBase/public/#EpiAware.EpiAwareBase.apply_method-Tuple%7BEpiProblem,%20AbstractEpiMethod,%20Any%7D) does to condition the user supplied `EpiProblem` to data. See more [here](https://turinglang.org/DynamicPPL.jl/stable/tutorials/prob-interface/#Conditioning-and-Deconditioning).
+
+#### Fixing and unfixing models
+
+Similarly to conditioning and deconditioning models, `DynamicPPL` supports fixing and unfixing models via the `fix` and `unfix` functions.
+Fixing is essentially saying that variables are constants (i.e replacing the right hand side of `~` with a value and changing the `~` to a `=`).
+A common use of this would be to simplify a prespecified model, for example to make the variance of a random walk be known versus estimated from the data.
+We also use this functionality in [`apply_method(::EpiProblem, ...)`](https://cdcgov.github.io/Rt-without-renewal/dev/lib/EpiAwareBase/public/#EpiAware.EpiAwareBase.apply_method-Tuple%7BEpiProblem,%20AbstractEpiMethod,%20Any%7D) to allow users to simplify `EpiProblems` on the fly. See more [here](https://turinglang.org/DynamicPPL.jl/stable/api/#DynamicPPL.fix).
