-Tpeold provides a Shiny interface for analyzing genes and finding TPE-OLD
-candidates based on known TPE-OLD genes.
+This package provides a graphical user interface for analyzing genes based on
+position data across species. It is a frontend for the R package
+[`geposan`](https://code.johrpan.de/johrpan/geposan). You can visit an example
+instance of the application [here](https://tpe-old.uni-rostock.de) where the
+method is used to find new
+[TPE-OLD](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4233240/) candidate
+genes based on the currently known ones.
 
 ## Installation
 
-You can install the development version of tpeold using:
+You can install the development version of `geposanui` using:
 
 ```r
 # install.packages("remotes")
 remotes::install_github("dreamRs/shinyvs")
-remotes::install_git("https://code.johrpan.de/johrpan/tpeold.git")
+remotes::install_git("https://code.johrpan.de/johrpan/geposanui.git")
 ```
 
 See [this page](https://remotes.r-lib.org/reference/install_git.html) for more
 information on this command.
 
+## Usage
+
+The main entry point is the `run_app()` function that is provided by the
+package. It will setup the initial analysis and provide the interactive user
+interface. You have to provide at least one gene set for the application to
+work. The following minimal example shows how to do that:
+
+```r
+# Ten random genes from Ensembl.
+my_interesting_genes <- c(
+    "ENSG00000142347",
+    "ENSG00000186174",
+    "ENSG00000143553",
+    "ENSG00000240972",
+    "ENSG00000105357",
+    "ENSG00000159251",
+    "ENSG00000258643",
+    "ENSG00000147873",
+    "ENSG00000158270",
+    "ENSG00000197616"
+)
+
+# Choose a name for your gene set.
+geposanui::run_app(list("Interesting genes" = my_interesting_genes))
+```
+
+This will run the application which you can reach using your favorite browser.
+For more information on the options provided by the function, take a look at the
+built-in documentation (`?geposanui::run_app`).
