+# Concordia Dockerized
+
+This page provides information about the provided docker images, their configuration and supported deployment
+strategies.
+
+TLDR: head down to [Putting it all together/Scripts](#piat-mkfile-targets) for a quick setup.
+
+## Services
+
+Concordia requires at the minimum two services to work, a blockchain and a rendezvous server.
+
+Additionally, the Concordia application code must be provided to the user. Currently, the only way of distributing the
+application code is via a webserver as a web application.
+
+### Ganache
+
+Ganache is a personal blockchain software used during development. It is a very convenient way of developing and testing
+dApps. More information can be found in the project's [website](https://www.trufflesuite.com/ganache).
+
+Note that any other Ethereum compliant blockchain can be used.
+
+### Rendezvous
+
+Concordia uses a distributed database to store forum data. A rendezvous server is needed in order for users to discover
+peers in the network and get access to the data.
+
+### Application
+
+The Concordia application is a React app that handles interactions with the contracts and the distributed database used.
+
+## Docker images
+
+This repository provides docker images to easily setup (and destroy) instances of all required services Concordia.
+Furthermore, we provide an image that builds the contracts and handles their migration to the blockchain in use.
+
+### Ganache
+
+The Dockerfile is provided in the path `./ganache`. The image makes use of the environment variables described
+bellow.
+
+| Environment variable | Default value | Usage |
+| --- | --- | --- |
+| ACCOUNTS_NUMBER | 10 | Set the number of accounts generated |
+| ACCOUNTS_ETHER | 100 | Set the amount of ETH assigned to each account |
+| MNEMONIC | NaN | The mnemonic phrase sued as a seed for deterministic account generation |
+| HOST | 0.0.0.0 | The hostname to listen on |
+| PORT | 8545 | The port to listen on |
+| NETWORK_ID | 5778 | The network id used to identify ganache |
+
+Note that the Ganache instance running inside the container will save the generated blockchain keys in the path
+`/home/ganache_keys/keys.json`. If you need to access the keys (eg for getting a private key and importing in Metamask)
+you can mount a volume to this path to have easier access.
+
+Also, the database used by Ganache for storing blockchain information is placed in the path `/home/ganache_db/`. You can
+maintain the blockchain state between runs by mounting a volume to the database path. To do that, add the docker flag 
+`-v host/absolute/path/to/ganache_db:/home/ganache_db`.
+
+### Rendezvous
+
+The rendezvous server used here is `js-libp2p-webrtc-star`. The server listens on port 9090. More information can be
+found on the github page of the project [here](https://github.com/libp2p/js-libp2p-webrtc-star).
+
+### Contracts
+
+This is a provision system that compiles and deploys the contracts to any Ethereum blockchain.
+
+A Dockerfile is provided in the path `./concordia-contracts` that will build the contracts used by Concordia and
+handle their deployment to any Ethereum network defined using env-vars upon container run. Dockerfile contains three
+useful stages, described in the table bellow.
+
+| Stage name | Entrypoint | Usage |
+| --- | --- | --- |
+| compile | Exits immediately | Compiles the contracts |
+| test | Runs contract tests | Compiles contracts and runs tests using blockchain defined by env vars |
+| runtime | Migrates contracts | Compiles contracts and migrates to the blockchain defined by env vars. Does **not** run tests |
+
+The image makes use of the environment variables described bellow.
+
+| Environment variable | Default value | Usage |
+| --- | --- | --- |
+| MIGRATE_NETWORK | develop | Set the network where the contracts will be deployed/tested (set this to "env" unless you know what you're doing) |
+| DEPLOY_CHAIN_HOST | NaN | Set the hostname of the blockchain network that will be used for deployment (requires network to be "env") |
+| DEPLOY_CHAIN_PORT | NaN | Set the port of the blockchain network that will be used for deployment (requires network to be "env") |
+| TEST_CHAIN_HOST | NaN | Set the hostname of the blockchain network that will be used for testing (requires network to be "env") |
+| TEST_CHAIN_PORT | NaN | Set the port of the blockchain network that will be used for testing (requires network to be "env") |
+
+You can find the contract artifacts in the directory `/usr/src/concordia/packages/concordia-contracts/build/` inside
+the image.
+
+**Attention**: make sure the targeted blockchain is up and running before trying to migrate the contracts.
+
+### Application
+
+The Dockerfile provided in the path `./concordia-application` builds the application for production and serves
+the resulting build using an nginx server. Dockerfile contains two useful stages, described in the table bellow.
+
+| Stage name | Entrypoint | Usage |
+| --- | --- | --- |
+| test | Runs tests | Fetches npm packages and runs tests |
+| runtime | Serves application | Builds for production and serves it through nginx |
+
+
+The image makes use of the environment variables described bellow.
+
+| Environment variable | Default value | Usage |
+| --- | --- | --- |
+| REACT_APP_RENDEZVOUS_HOST | 127.0.0.1 | Set the hostname of the rendezvous server |
+| REACT_APP_RENDEZVOUS_PORT | 9090 | Set the port of the rendezvous server |
+
+**Attention**: this image will copy the contract artifacts from the directory `/packages/concordia-contracts/build`.
+The image is bound the these artifacts after build. If the contracts change or get re-deployed the image must be
+re-built to use the new artifacts.
+
+**Attention**: make sure the contracts have been deployed before **building** this image. Also, make sure the rendezvous
+server is up and running.
+
+## Docker Compose
+
+A docker-compose file also is provided. The docker-compose handles the lifecycle of the Ganache and Rendezvous server
+containers.
+
+## Putting it all together
+
+You can find some ready to use scripts for common scenarios like dev deploys and testing in the `./docker` directory.
+These scripts are documented in the following chapters.
+
+### <a name="piat-mkfile-targets"></a> Makefile targets
+
+Concordia uses blockchain and other distributed technologies. There are a number of ways to set up a running instance of
+this application.
+
+This chapter will guide you through simple setups for testing and production that depend on local blockchain (ganache)
+instances which do not require real ETH to work or have any other charges.
+
+#### Testing the contracts
+
+Build the ganache image and spin up a blockchain for testing:
+
+```shell
+make build-ganache run-ganache-test
+```
+
+Build the testing stage of the contracts image:
+
+```shell
+make build-contracts-tests
+```
+
+Run the tests:
+
+```shell
+make run-contracts-tests
+```
+
+The results should be printed in the terminal, but are also available in the directory `./reports/contracts`.
+
+#### Testing the application
+
+Build the testing stage of the application image:
+
+```shell
+make build-app-tests
+```
+
+Run the test:
+
+```shell
+make run-app-tests
+```
+
+The results should be printed in the terminal, but are also available in the directory `./reports/app`.
+
+#### Production
+
+Just run the target:
+
+```shell
+make run
+```
+
+And you' re done! Head to [localhost:7777](localhost:7777) and voilà, a working Concordia instance appears! The
+blockchain is exposed in the address `localhost:8545`.
+
+**Tip**: the accounts (private keys) generated by Ganache are available in the file `./volumes/ganache_keys/keys.json`.
+
+Note that the `make run` command might take several minutes to execute (depending on your system). What happens under
+the hood is that:
+
+- the ganache image is built
+- blockchain and rendezvous server containers are started
+- migration stage of the contracts image is built
+- the contracts are deployed to the blockchain:
+- the application image is built and then deployed
+
+### Env Files
+
+Targets in the Makefile make use of env files suffixed by `.docker` located in the directory `./env`. Using this
+environment variables, you can change various configuration options of the testing/production deploys.
+
+Targets suffixed with `host-chain` will try to use a blockchain and rendezvous server running in the host machine. They
+use the `--net=host` docker option and get the required environment variables from different env files,
+`./env/contracts.env` and `./env/concordia.env` (notice these env files don't include the `.docker`). These env files do
+not exist by default. The values set will largely depend on how you choose to run services in your system (which ports
+you use etc.), so be sure to create them before running any `host-chain` target. Luckily example files are provided.

+# Concordia Contracts Package
+
+This is the package where the contracts that power Concordia live.
+
+## Compile contracts
+
+```shell script
+yarn compile
+```
+
+## Lint contracts (and tests)
+```shell script
+yarn lint
+```
+
+## Migrate contracts
+Default host and port values of the blockchain are:
+
+| host | port |
+|---|---|
+| 127.0.0.1 | 8545 |
+
+Migrate (using the development network by default):
+```shell script
+yarn migrate
+```
+
+### Setting different host and port values
+Define the host and port of the blockchain in use.
+
+Linux:
+```shell script
+export CHAIN_HOST="127.0.0.1"
+export CHAIN_PORT="7545"
+```
+
+Windows:
+```shell script
+SET CHAIN_HOST="127.0.0.1"
+SET CHAIN_PORT="7545"
+```
+
+Migrate using the `env` network :
+```shell script
+yarn _migrate --network env
+```
+**Notice the underscore `_` suffix in the script name. This is not a mistake.**
+
+## Test contracts
+Default host and port values of the blockchain are:
+
+| host | port |
+|---|---|
+| 127.0.0.1 | 8546 |
+
+
+Test:
+```shell script
+yarn test
+```
+
+### Setting different host and port values
+Define the host and port of the blockchain in use like above.
+
+Test:
+```shell script
+yarn test --network env
+```
