-## hex encode/decode tool
-
-### Requirements
-
-- Docker >= 18.x
-- GNU Make >= 3.81
-
-### Building
-
-```bash
-$ cd sys-utils/hex
-$ make
-```
-
-#### Makefile targets
-
-The following options are available as `make` targets:
-
-- **all**: builds the RISC-V hex executable
-- **extra.ext2**: builds the extra.ext2 filesystem image with the hex tool inside
-- **toolchain-env**: runs the toolchain image with current user UID and GID
-- **clean**: clean generated artifacts
-
-#### Makefile container options
-
-You can pass the following variables to the make target if you wish to use different docker image tags.
-
-- TOOLCHAIN\_IMAGE: toolchain image name
-- TOOLCHAIN\_TAG: toolchain image tag
-
-```
-$ make TOOLCHAIN_TAG=mytag
-```
-
-It's useful when you want to use prebuilt images like `cartesi/toolchain:latest`
-
-#### Usage
-
-The purpose of the hex tool please see the emulator documentation.
-
-The purpose of the `extra.ext2` image is to help the development creating a filesystem that contains the hex tool so it can be used with the emulator. For instructions on how to do that, please see the emulator documentation.
