+This is a Chrome extension which lets you define a blacklist of keywords.
+Any posts in your Google+ stream that match to any of these keywords are filtered from the stream.
+
+
+**This is a CoffeeScript port by Markus Birth.**
+The original version of Ryad El-Dajani is [here](https://github.com/ryad-eldajani/gplusblacklist).
+
+
+Compilation
+-----------
+
+To compile this extension, make sure you have installed the CoffeeScript compiler.
+
+Then just run:
+
+```
+make
+```
+
+It will compile everything and the final extension ends up in the `build/` directory.
+
+
+
+Installation
+------------
+
+To install the extension into your Chrome or Chromium browser, go to *Menu* → *Tools* → *Extensions*,
+enable *Developer Mode* and load the `build/` directory using the **Load unpacked extension…** button.
+
+
+
+Distribution
+------------
+
+If you want to create a Chrome Extension **.crx** package, just run:
+
+```
+make crx
+```
+
+It will generate an RSA key if needed and compile everything into a `gplusblacklist.crx`.
+That file can then be distributed.
