 ## Conventions
 
-- Most libraries are internal libraries and have APIs which are completely unstable! There are few or no restrictions on backwards compatibility or rules about external dependencies. Exceptions are *libbitcoin_consensus* and *libbitcoin_kernel* which have external interfaces documented at [../shared-libraries.md](../shared-libraries.md).
+- Most libraries are internal libraries and have APIs which are completely unstable! There are few or no restrictions on backwards compatibility or rules about external dependencies. An exception is *libbitcoin_kernel*, which, at some future point, will have a documented external interface.
 
 - Generally each library should have a corresponding source directory and namespace. Source code organization is a work in progress, so it is true that some namespaces are applied inconsistently, and if you look at [`libbitcoin_*_SOURCES`](../../src/Makefile.am) lists you can see that many libraries pull in files from outside their source directory. But when working with libraries, it is good to follow a consistent pattern like:
