7. Title the PR in a meaningful way and describe the rationale and the thought process in the PR description.
8. Write clean, thoughtful, and detailed [commit messages](https://chris.beams.io/posts/git-commit/). This is even more important than the PR description, because commit messages are stored _inside_ the Git history. One good rule is: if you are happy posting the commit message as the PR description, then it's a good commit message.
## Basic Build Instructions
**System-specific Software Dependencies**:
Building Lotus requires some system dependencies, usually provided by your distribution.
Ubuntu/Debian:
```
sudo apt install mesa-opencl-icd ocl-icd-opencl-dev gcc git bzr jq pkg-config curl clang build-essential hwloc libhwloc-dev wget -y && sudo apt upgrade -y
```
Fedora:
```
sudo dnf -y install gcc make git bzr jq pkgconfig mesa-libOpenCL mesa-libOpenCL-devel opencl-headers ocl-icd ocl-icd-devel clang llvm wget hwloc libhwloc-dev
```
For other distributions you can find the required dependencies [here.](https://docs.filecoin.io/get-started/lotus/installation/#system-specific) For instructions specific to macOS, you can find them [here.](https://docs.filecoin.io/get-started/lotus/installation/#macos)
#### Go
To build Lotus, you need a working installation of [Go 1.16.4 or higher](https://golang.org/dl/):
```bash
wget -c https://golang.org/dl/go1.16.4.linux-amd64.tar.gz -O - | sudo tar -xz -C /usr/local
```
**TIP:**
You'll need to add `/usr/local/go/bin` to your path. For most Linux distributions you can run something like:
```shell
echo "export PATH=$PATH:/usr/local/go/bin" >> ~/.bashrc && source ~/.bashrc
```
See the [official Golang installation instructions](https://golang.org/doc/install) if you get stuck.
### Build and install Lotus
Once all the dependencies are installed, you can build and install the Lotus suite (`lotus`, `lotus-miner`, and `lotus-worker`).
1. Clone the repository:
```sh
git clone https://github.com/filecoin-project/lotus.git
cd lotus/
```
Note: The default branch `master` is the dev branch where the latest new features, bug fixes and improvement are in. However, if you want to run lotus on Filecoin mainnet and want to run a production-ready lotus, get the latest release[ here](https://github.com/filecoin-project/lotus/releases).
2. To join mainnet, checkout the [latest release](https://github.com/filecoin-project/lotus/releases).
If you are changing networks from a previous Lotus installation or there has been a network reset, read the [Switch networks guide](https://docs.filecoin.io/get-started/lotus/switch-networks/) before proceeding.
For networks other than mainnet, look up the current branch or tag/commit for the network you want to join in the [Filecoin networks dashboard](https://network.filecoin.io), then build Lotus for your specific network below.
```sh
git checkout <tag_or_branch>
# For example:
git checkout <vX.X.X> # tag for a release
```
Currently, the latest code on the _master_ branch corresponds to mainnet.
3. If you are in China, see "[Lotus: tips when running in China](https://docs.filecoin.io/get-started/lotus/tips-running-in-china/)".
4. This build instruction uses the prebuilt proofs binaries. If you want to build the proof binaries from source check the [complete instructions](https://docs.filecoin.io/get-started/lotus/installation/#build-and-install-lotus). Note, if you are building the proof binaries from source, [installing rustup](https://docs.filecoin.io/get-started/lotus/installation/#rustup) is also needed.
5. Build and install Lotus:
```sh
make clean all #mainnet
# Or to join a testnet or devnet:
make clean calibnet # Calibration with min 32GiB sectors
make clean nerpanet # Nerpa with min 512MiB sectors
sudo make install
```
This will put `lotus`, `lotus-miner` and `lotus-worker` in `/usr/local/bin`.
`lotus` will use the `$HOME/.lotus` folder by default for storage (configuration, chain data, wallets, etc). See [advanced options](https://docs.filecoin.io/get-started/lotus/configuration-and-advanced-usage/) for information on how to customize the Lotus folder.
6. You should now have Lotus installed. You can now [start the Lotus daemon and sync the chain](https://docs.filecoin.io/get-started/lotus/installation/#start-the-lotus-daemon-and-sync-the-chain).
