+To get into EOF through ceofhack, you should make sure you understand

+interests, you may either be interested in
+
+ * hacking the core (aka ceofhack, rare developers probably)
+ * creating user interfaces (ui)
+ * creating transport protocols (tp)
+
+## API documentation
+
+In general, everything you need should be documented in the
+EOF standard document. If it's not, it's probably a bug
+(in that case, send a patch).
+
+## UI developers
+
+UIs can either live in their own projects or be a part of
+ceofhack. The **first** way is recommended, so your development
+does not depend on ceofhack.
+
+## Transport protocol developers
+
+TPs can either live in their own projects or be a part of
+ceofhack. The **second** way is recommended, so all available
+transport protocols are shared with the ceofhack installation.
+
+### Creating a new transport protocol
+
+You can use the following code as a start:
+
+    scheme=phpbb
+    implementation=shell
+    cd ceofhack/tp
+    mkdir -p ${scheme}/${implementation}
+    echo "echo listening implementation" > ${scheme}/${implementation}/listen
+    echo "echo send implementation" > ${scheme}/${implementation}/send
+    chmod 0755 ${scheme}/${implementation}/*
+
+Now you've a dummy "working" transport protocol.
+
+### Enabling a new transport protocol
+
+You can use the following code as a start:
+
+    scheme=phpbb
+    implementation=shell
+    cd ceofhack/tp
+
+    # Enable protocol in general
+    mkdir -p "$HOME/.ceof/tp/available/${scheme}"
+    cp "${scheme}/${implementation}/listen" "$HOME/.ceof/tp/available/${scheme}"
+    cp "${scheme}/${implementation}/send" "$HOME/.ceof/tp/available/${scheme}"
+
+    # Enable listener for protocol
+    address="describe-particular-address"
+    mkdir -p "$HOME/.ceof/tp/listen/${scheme}-${address}"
+    echo "${scheme}${address}" > "$HOME/.ceof/tp/listen/${scheme}-${address}/url"
