 # Github Users
 If you are visiting this repository on GitHub, you are on a mirror of
-https://git.friedl.net/playground/suckless-quark. This mirror is regularily
-updated with my other GitHub mirrors. In contrast to other projects I do not
-intend to move this tree to GitHub in the future. It is meant to stay a
-read-only mirror.
+https://git.friedl.net/incubator/dirl. This mirror is regularily updated with my
+other GitHub mirrors. 
 
-You are welcome to pull any changes from this repository into your quark tree.
-If you want to contribute consider [contributing](http://suckless.org/hacking/)
-directly to [upstream](http://suckless.org/community/).
+Like with my other incubator projects, once I consider `dirl` reasonable stable
+the main tree will move on GitHub.
 
-If you still - for whichever reasons - want to contribute to my tree directly,
-feel free to send patches to dev[at]friedl[dot]net. Alternatviely you can issue
-a pull request on GitHub which will be cherry picked into my tree.
+Dirl is built upon [quark](tools.suckless.org/quark/). You are welcome to pull
+any changes from this repository into your own quark tree. If you want to
+contribute consider [contributing](http://suckless.org/hacking/) directly to
+[upstream](http://suckless.org/community/).
+
+If you want to contribute to `dirl` directly, feel free to send patches to
+dev[at]friedl[dot]net. Alternatviely, you can issue a pull request on GitHub
+which will be cherry picked into my tree. If you plan significant long-term
+contributions drop me a mail for access to the incubator repository.
