+# Joining the Community
+
+## Charter
+
+The rules for community engagement are covered under the [SOAFEE Charter](/about/charter), we aim to be an open, friendly respectful and collaborative community.  Please refer to the charter for more details. 
+
+## Slack
+
+The community makes extensive use of Slack for all transient communication.  We are currently using the free tier of slack, so have limited access to features and history.  If you want to create a persistent document or content, please make use of the Google Workspace resource outlined below.
+
+Please use this link to [join the SOAFEE Slack community](https://join.slack.com/t/soafee/shared_invite/zt-12e17668h-DttNpOtyFNi5H1udojYmtg)
+
+Please explore the channels that are of interest to you.  We tend to create a channel that maps to steering committees and working groups.
+
+## Google Workplace
+
+The SOAFEE project makes use of Google Workplace for meetings, documents and collaboration.  Each signed up member company will be given two @soafee.io accounts, but you don't need to have one of these accounts to collaborate with the SOAFEE community.  We aim to have all documents available read-only to anybody who wants access, there may be errors made by community members when setting up documents, if you have trouble accessing a document, please contact info@soafee.io.  If you would like edit access to documents, please read the section below about joining a workspace group below.
+
+### Groups
+
+There are three main groups that manage access to documents.  Please request to join the group that represents your role within SOAFEE community
+
+{{< table >}}
+| Group Name      | Joining URL |
+| --------------- | ----------
+| Governing Body  | [GB](https://groups.google.com/a/soafee.io/g/gb)

+| Marketing Steering Committee | [MSC](https://groups.google.com/a/soafee.io/g/msc)

+Once you have membership of a group, this should give you edit permissions for shared documents under that function.

+
+## Jira
+
+Jira is used to track and manage all engineering efforts.  Currently, Jira accounts are limited to SOAFEE members with @soafee.io accounts so only these members will be able to create tickets.  We currently allow comments on tickets by any anonymous users, so anybody in the ecosystem can comment on existing tickets.
