-One or more token transfers can be added to a transaction by calling the `add_transfer` method.
+You may also refer to `example/transaction.py` on how to use a high level function `bank_send()` to sign and broadcast a transaction
 
-When the transaction is fully prepared, calling `get_pushable` will return a signed transaction in the form of a JSON string.
-This can be used as request body when calling the `POST /txs` endpoint of rpc.

+### Set up development environment<a name="set-up-development-environment"></a>
+
+More about [poetry](https://python-poetry.org/docs/).
+
+```
+poetry install
+```
+
+### Generate gRPC code<a name="generate-grpc-code"></a>
+
+```
+poetry shell
+./generated_protos.sh
+```
+
+**NOTE:** By default, `master` branch of `cosmos-sdk` is used. Use command below to download a different version:
+
+```
+./generated_protos.sh -COSMOS_REF=v0.44.5
+```
+
+If more generated gRPC code is needed in the future, please add the `.proto` files needed here in `generated_protos.sh`:
+
+```bash
+# Add .proto files here to generate respective gRPC code
+PROTO_FILES="
+$COSMOS_SDK_DIR/proto/cosmos/auth/v1beta1/auth.proto
+...
+```
+
+### Tox<a name="tox"></a>
+
+```
+pyenv local 3.7.a 3.8.b 3.9.c
+```
+
+`a`, `b` and `c` is python versions installed on your computer by `pyenv`. More about [pyenv](https://github.com/pyenv/pyenv).
+
+After this command, a `.python-version` file will be generated at project root directory, which means python versions inside `.python-version` are presented for this project. So running `tox` command with `py{37,38,39}` configuration should succeed.\
+Then run to verify. This command is recommended to run before pushing a commit.
+
+```sh
+poetry run tox
+# or
+poetry shell
+tox
+```
