+
+TwPM project aims to increase the trustworthiness of the TPM module (hence the
+TwPM), by providing the open-source firmware implementation for the TPM device,
+compliant to the TCG PC Client Specification. Project aims to use already
+available open-source software components whenever possible (such as TPM
+simulators for TPM commands handling), while developing new code when necessary
+(such as LPC FPGA module, or low-level TPM FIFO interface handling).
+
+This project was funded through the [NGI Assure Fund](https://nlnet.nl/assure),
+a fund established by [NLnet](https://nlnet.nl/) with financial support from the
+European Commission's [Next Generation Internet](https://ngi.eu/) programme,
+under the aegis of DG Communications Networks, Content and Technology under
+grant agreement No 957073.
+
+The project just entered a phase in which all basic components can communicate
+with each other. This should be enough to test simplest commands that don't
+require use of parts that aren't implemented yet. Nonvolatile storage, true
+randomness source and primary keys' certificates manufacturing process are yet
+to be implemented. As such, in current state TwPM cannot be used for all use
+cases of TPM, but we're slowly getting there.

+## SBOM
+
+TDB: add links and revisions to code:
+- TPM stack - Zephyr etc.
+- top module
+- TPM registers module
+- LPC module
+
+## Compiling and flashing
+
+TBD: update documentation and link it here
+
+## Connecting to the mainboard
+
+TBD: choose mainboard(s), add table(s) with connections
+
+## Test suite
+
+TBD: link to test suite, results, demo of running tests?
+
+## Known issues and limitations
+
+TBD: if any
+
+## Summary
+
