+# Easy Cozy configuration
+
+This section includes all configurations available for the stack.
+
+## Configuration File
+
+The configuration file of the stack is located at `.easy-cozy/cozystack/cozy.yml`. It can be edit in order to changes various parameters, smtp, logs ...
+
+## SMTP
+
+### Install a specific version of an app
+
+Modif the `cozy.yml` responsible for the configuration :
+
+```yml
+mail:
+  # mail noreply address - flags: --mail-noreply-address
+  noreply_address: noreply@localhost
+  noreply_name: My Cozy
+  reply_to: support@cozycloud.cc
+  # mail smtp host - flags: --mail-host
+  host: smtp.home
+  # mail smtp port - flags: --mail-port
+  port: 465
+  # mail smtp username - flags: --mail-username
+  username: {{.Env.COZY_MAIL_USERNAME}}
+  # mail smtp password - flags: --mail-password
+  password: {{.Env.COZY_MAIL_PASSWORD}}
+  # disable mail tls - flags: --mail-disable-tls
+  disable_tls: false
+  # skip the certificate validation (may be useful on localhost)
+  skip_certificate_validation: false
+```
+
+According to cozy-stack issue: https://github.com/cozy/cozy-stack/issues/2009 you might need to change above configuration with :
+
+```yml
+mail:
+  # mail smtp port - flags: --mail-port
+  port: 587
+  # disable mail tls - flags: --mail-disable-tls
+  disable_tls: true
+```
+
+After updating configuration don't forget to restart your cozy-stack :
+```bash
+docker-compose restart cozy
+```

+# Release
+
+This section will show you how to properly create a release for the app.
+
+## Conventionnal commit
+
+The Conventional Commits specification is a lightweight convention on top of commit messages. It provides an easy set of rules for creating an explicit commit history; which makes it easier to write automated tools on top of. This convention dovetails with SemVer, by describing the features, fixes, and breaking changes made in commit messages.
+
+The commit message should be structured as follows:
+
+```
+<type>[optional scope]: <description>
+
+[optional body]
+
+[optional footer(s)]
+```
+
+The commit contains the following structural elements, to communicate intent to the consumers of your library:
+
+* fix: a commit of the type fix patches a bug in your codebase (this correlates with PATCH in Semantic Versioning).
+* feat: a commit of the type feat introduces a new feature to the codebase (this correlates with MINOR in Semantic Versioning).
+* BREAKING CHANGE: a commit that has a footer BREAKING CHANGE:, or appends a ! after the type/scope, introduces a breaking API change (correlating with MAJOR in Semantic Versioning). A BREAKING CHANGE can be part of commits of any type.
+* types other than fix: and feat: are allowed, for example @commitlint/config-conventional (based on the the Angular convention) recommends build:, chore:, ci:, docs:, style:, refactor:, perf:, test:, and others.
+* footers other than BREAKING CHANGE: <description> may be provided and follow a convention similar to git trailer format.
+
+## standard-version
+
+Standard-version is librairie javascript that allow to handle easly tags and changelog file.
+
+Just run the following command in order to create a release tag, bump package.json version and upadte changelog file.
+
+```bash
+yarn run release -- --release-as X.X.X # replace with version number (ex: 1.2.0)
+```

+Konnectors are scripts that import data from a web service and put those data into cozy. Each konnector is an independant application managed by the cozy home application.
+
+Ecolyo uses data from 3 web services : 
+
+- Enedis
+- Grdf
+- Eau du grand lyon (EGL)
+
+All the konnectors are configured to retrieve user's data as far as 3 years back.
+Some variation have to be considered :
+
+- When the user launches the konnector manually, it fetches 1 year of data (in order to reduce running time).
+- When a konnector is launched by the cozy stack (at a random time between 10am and 11am), it fetches 3 years of data.
