I did a trick there to keep the CSS out of the markdown.

| Number of sequences of transactions to generate during testing. |

I think these are transactions, not sequences of transactions.

This needs a better explanation: we need to explain that every N transaction, the VM is reset to the state after contract deployment. This also limits the size of each sequence in the corpus.

| | Int | `null` | \* | `--timeout N` | | ||
|
|

Explain how testLimit and timeout interacts.

| List of addresses to (randomly) use for the transactions sent during testing. |

Explain how the sender is used for normal transactions / assertions, instead of properties.

Same as previous one

Explain that out of gas will cause the property to fail

Explain that out of gas will NOT cause assertions to fail.

If using z3, this timeout is not global, but per query (and this is a very important detail 😆)

Clarify that there is only a single symexec worker, but we can have multiple threads to solve queries.

Add alternative ENV variable?
