 Transpilers for building BSON documents in any language. Current support
-provided for `shell` `javascript` and `python` as inputs. `java`, `c#`, `node`, `shell`, `python`, `ruby` and `go` as outputs.
-
-> ⚠️  `shell` output produces code that is compatible only with legacy `mongo` shell not the new `mongosh` shell. See [COMPASS-4930](https://jira.mongodb.org/browse/COMPASS-4930) for some additional context

+**NOTES:**
+1. A version of the code with support for `python` with corresponding test cases has been removed to avoid bundling and supporting unused code, however it can be still be found in https://github.com/mongodb-js/compass/tree/80cf701e44cd966207f956fac69e8233861b1cd5/packages/bson-transpilers.
+2. The `shell` output is disabled as is essentially the only input in use and it produces code that is compatible only with legacy `mongo` shell not the new `mongosh` shell. See [COMPASS-4930](https://jira.mongodb.org/browse/COMPASS-4930) for some additional context.
