 Tatajuba (_Bagassa guianensis_) is a South American tree, also known as Tatajubá, Tatajuva, Garrote, Totajuba.
 If I'm not mistaken it means "yellow fire" in [Tupi](https://en.wikipedia.org/wiki/Tupi_language).
 
+## Installation
+You should download this repository with `git clone --recursive` to ensure it also downloads
+[biomcmc-lib](https://github.com/quadram-institute-bioscience/biomcmc-lib).
+
+This sofware uses `autotools`, so you can install it with `configure` + `make`. I'll add more instructions later, but
+remember to define where you want it installed with `configure --prefix=DIR`. 
+It will compile from the directories `biomcmc-lib`, `kalign`, and `bwa` before finally compiling `tatajuba`.
+Notice that this does **not** generate the usual executables for `kalign` or `bwa` (only their libraries are used here).
