@@ -51,10 +51,10 @@ To document a new error code, the following workflow can be convenient.
 We keep track of which errors are being worked on, and which still require documentation,
 using a bunch of issues:
 
-- [All error codes that still need documenting are collected here](https://github.com/haskell/error-messages/issues/162). This issue contains links to individual issues for every error, allowing the list to be updated as PRs are merged. These individual issues for every error may also contain helpful links to test cases, suggestions on examples, and useful metadata to a contributor.
-- There is also an (incomplete) list of issues tagged `good first issue`; these are errors which are especially good for newer contributors to document (no incredibly esoteric type-level errors that are hard to understand, let alone describe!): https://github.com/haskell/error-messages/labels/good%20first%20issue
-- Issues related to improving the site, the workflow for contributing, or other information are tagged `error-message-index-site`: https://github.com/haskell/error-messages/labels/error-message-index-site
-- Issues related to improving, clarifying, or extending existing documentation are tagged `error-message-index-improvements`: https://github.com/haskell/error-messages/labels/error-message-index-improvements
