+# Monero Development Harness
+
+Monero development Harness - documentation and notes
+
+## Useful Info
+
+Monero is very different than btc in that it does not provide a single rpc
+tool like `bitcoin-cli` but rather a set of json 2.0 & other older json apis
+which can be accessed by sending curl requests for each one.
+
+Monero wallets are accounts based
+
+<https://web.getmonero.org/resources/moneropedia/account.html>
+
+## Architecture
+
+![alt text](image-1.png)
+
+Embedded in Tmux
+
+- **alpha** is a monero p2p daemon
+
+- **bill** is a miner wallet .. you can top up more funds from bill if you run out
+
+- **fred** is a normal wallet user
+
+- **charlie** is a normal wallet user
+
+- **charlie_view** is a view-only wallet sibling of charlie full wallet - no spend key
+
+## Using
+
+### Prerequisites
+
+- **monero-x86_64-linux-gnu-v0.18.3.3** or later <https://downloads.getmonero.org/cli/linux64>
+- **linux** (tested on Ubuntu 22.04)
+- **jq** (1.6)
+
+### Setup
+
+**monero-x86_64-linux-gnu-v0.18.3.3** should be in PATH
+
+`export PATH=$PATH:[path-to]/monero-x86_64-linux-gnu-v0.18.3.3`
+
+### Background Mining
+
+By default background mining is set up and mines to bill wallet every 15s
+
+To disable:
+
+`export NOMINER="1" to your shell`
+
+ or else invoke the harness with:
+
+`NOMINER="1" ./harness.sh`
+
+You should disable if attempting the manual offline cold signing using `monero-wallet-cli`
+
+You should also ctl-C charlie & charlie_view wallets for this
+
+### Run
+
+`./harness.sh`
+
+### Data Directory
+
+![alt text](image-2.png)
+
+### Known Issues
+
+The transaction spend locking needs more investigation
+
+### Commands Help
+
+run `./help` from the tmux harness window 0
+
