+Capabilities
+************
+
+.. note::
+    I wrote this section with the little knowledge I have of the capabilities
+    system; I work mainly by testing different possibilities until I get what
+    I want.
+    As for all the documentation, feel free to contact me to
+    correct/enhance it.
+
+First, you should know how capabilities work
+:ref:`on the user side <capabilities>`.
+
+Checking for a capability given its name
+========================================
+
+You only have to use ``ircdb.checkCapability(prefix, 'capability')``.
+
+You can also override some behavior of the capability system. Here is the
+complete documentation of ``ircdb.checkCapabiltiy``:
+
+.. autofunction:: supybot.ircdb.checkCapability
+    :noindex:
+
+Manipulating capability names
+=============================
+
+Althrough you can manipulate capability names with string operations,
+Supybot provides a few methods to do that “in the abstract” (could be
+useful if we change the capability syntax one day…):
+
+.. autofunction:: supybot.ircdb.isCapability
+    :noindex:
+
+.. autofunction:: supybot.ircdb.makeChannelCapability
+    :noindex:
+
+.. autofunction:: supybot.ircdb.isChannelCapability
+    :noindex:
+
+.. autofunction:: supybot.ircdb.makeAntiCapability
+    :noindex:
+
+.. autofunction:: supybot.ircdb.unAntiCapability
+    :noindex:
+
+.. autofunction:: supybot.ircdb.invertCapability
+    :noindex:
+
+.. autofunction:: supybot.ircdb.isAntiCapability
+    :noindex:
+
+.. autofunction:: supybot.ircdb.canonicalCapability
+    :noindex:
