 This project has some overlap with other R packages:
 
-- [`{bpmodels}`](https://github.com/epiverse-trace/bpmodels) is another
-  Epiverse-TRACE R package that analyses transmission chain data to
-  infer the transmission process for either the size or length of
-  transmission chains. Two main differences between the packages are: 1)
-  `{superspreading}` has more functions to compute metrics that
+- [`{epichains}`](https://github.com/epiverse-trace/epichains) is
+  another Epiverse-TRACE R package that analyses transmission chain data
+  to infer the likelihood for either the size or length of an outbreak
+  cluster, or simulate transmission chains. It is based on the, now
+  retired, [`{bpmodels}`](https://github.com/epiforecasts/bpmodels)
+  package.
+
+  Two main differences between `{superspreading}` and `{epichains}`
+  are: 1) `{superspreading}` has functions to compute metrics that
   characterise outbreaks and superspreading events
-  (e.g. `probability_epidemic()` & `probability_extinct()`); 2)
-  `{bpmodels}` can simulate a branching process (`chain_sim()`) with a
-  specified process (e.g. negative binomial).
+  (e.g. `probability_epidemic()`, `probability_extinct()`,
+  `proportion_cluster_size()` & `proportion_transmission()`); whereas
+  `{epichains}` has functions to calculate the likelihood of a
+  transmission chains’ size and length. 2) `{epichains}` exports
+  functions to simulate a single-type branching process
+  (`simulate_chains()` & `simulate_chain_stats()`).
+
+- [`{modelSSE}`](https://CRAN.R-project.org/package=modelSSE) has a
+  similar scope to `{superspreading}`, it contains functions to infer
+  offspring distribution parameters. It exports several infectious
+  disease outbreak datasets (see `data(package = "modelSSE")`). Both
+  `{superspreading}` and `{modelSSE}` export functions to calculate the
+  proportion of transmission using different methods. It also imports
+  the [`{Delaporte}`](https://CRAN.R-project.org/package=Delaporte)
+  package to model the offspring distribution as a Delaporte
+  distribution.
