-# Development tasks
+The `{tlf}` package provides an object-oriented framework to create
+tables and figures, which are used by R packages in the Open Systems
+Pharmacology ecosystem:
+
+-   [`{ospsuite}`](https://www.open-systems-pharmacology.org/OSPSuite-R/)
+-   [`{ospsuite.reportingengine}`](https://www.open-systems-pharmacology.org/OSPSuite.ReportingEngine/)
 
-## dev_mode
+## Installation
 
-`devtools::dev_mode` function switches your version of R into "development mode". This is useful to avoid clobbering the existing versions of CRAN packages that you need for other tasks. Calling dev_mode() again will turn development mode off, and return you to your default library setup.
+You can install the development version of `{tlf}` from
+[GitHub](https://github.com/) with:
 
-```R
-# This will install the package in the folder C:/Rpackages
-devtools::dev_mode(path="C:/Rpackages")
+``` r
+# install.packages("remotes")
+remotes::install_github("Open-Systems-Pharmacology/TLF-Library")
 ```
 
-## Reload the package
+`{tlf}` requires following packages to be installed:
 
-```R
-devtools::load_all()
-```
+From CRAN:
+
+-   [ggplot2](https://cran.r-project.org/package=ggplot2/index.html)
+-   [jsonlite](https://cran.r-project.org/package=jsonlite/index.html)
+-   [patchwork](https://cran.r-project.org/package=patchwork/index.html)
+-   [R6](https://cran.r-project.org/package=R6/index.html)
+
+Must be downloaded manually:
 
-or `Ctrl + Shift + L`
+-   [ospsuite.utils](https://github.com/Open-Systems-Pharmacology/OSPSuite.RUtils/releases/download/v1.3.17/ospsuite.utils_1.3.17.zip)
 
-## Add or update script files
+## Documentation
 
-`.R` files defined in `tests\dev\` will be removed from the package and can be used to simulate interaction with the package. See [scripts.R](tests/dev/scripts.R)
+A detailed account of existing functions and articles on how to use them
+can be found on the [dedicated
+website](https://www.open-systems-pharmacology.org/TLF-Library/).
