-### LFS setup
-
-This repository externalises large files so that they do not bulk up the git repo itself.
-This is done through a tool called `git-lfs`, which must be installed for it to work.
-Additionally, we use a custom agent to store our LFS objects in S3 (rather than the default and more expensive Github LFS service).
-
-In order to setup our s3 based lfs:
-
-1) Install [tkinfra](https://github.com/tkhq/mono/tree/main/src/go/tkinfra)
-2) Run `./scripts/setup-lfs.sh`
-
-#### Troubleshooting
-
-Our mono repo uses the same lfs configuration. For troubleshooting tips consult monos [LFS troubleshooting](https://github.com/tkhq/mono#troubleshooting-lfs) section.
