+# ADR Creation Process
+
+1. Copy the `adr-template.md` file. Use the following filename pattern: `adr-next_number-title.md`
+2. Create a draft Pull Request if you want to get an early feedback.
+3. Make sure the context and a solution is clear and well documented.
+4. Add an entry to a list in the [README](./README.md) file.
+5. Create a Pull Request to propose a new ADR.
+
+## ADR life cycle
+
+ADR creation is an **iterative** process. Instead of trying to solve all decisions in a single ADR pull request, we MUST firstly understand the problem and collect feedback through a GitHub Issue.
+
+1. Every proposal SHOULD start with a new GitHub Issue or be a result of existing Issues. The Issue should contain just a brief proposal summary.
+
+2. Once the motivation is validated, a GitHub Pull Request (PR) is created with a new document based on the `adr-template.md`.
+
+3. An ADR doesn't have to arrive to `master` with an _accepted_ status in a single PR. If the motivation is clear and the solution is sound, we SHOULD be able to merge it and keep a _proposed_ status. It's preferable to have an iterative approach rather than long, not merged Pull Requests.
+
+4. If a _proposed_ ADR is merged, then it should clearly document outstanding issues either in ADR document notes or in a GitHub Issue.
+
+5. The PR SHOULD always be merged. In the case of a faulty ADR, we still prefer to  merge it with a _rejected_ status. The only time the ADR SHOULD NOT be merged is if the author abandons it.
+
+6. Merged ADRs SHOULD NOT be pruned.
+
+### ADR status
+
+Status has two components:
+
+```
+{CONSENSUS STATUS} {IMPLEMENTATION STATUS}
+```
+
+IMPLEMENTATION STATUS is either `Implemented` or `Not Implemented`.
+
+#### Consensus Status
+
+```
+DRAFT -> PROPOSED -> LAST CALL yyyy-mm-dd -> ACCEPTED | REJECTED -> SUPERSEDED by ADR-xxx
+                  \        |
+                   \       |
+                    v      v
+                     ABANDONED
+```
+
++ `DRAFT`: [optional] an ADR which is work in progress, not being ready for a general review. This is to present an early work and get an early feedback in a Draft Pull Request form.
++ `PROPOSED`: an ADR covering a full solution architecture and still in the review - project stakeholders haven't reached an agreed yet.
++ `LAST CALL <date for the last call>`: [optional] clear notify that we are close to accept updates. Changing a status to `LAST CALL` means that social consensus (of Cosmos SDK maintainers) has been reached and we still want to give it a time to let the community react or analyze.
++ `ACCEPTED`: ADR which will represent a currently implemented or to be implemented architecture design.
++ `REJECTED`: ADR can go from PROPOSED or ACCEPTED to rejected if the consensus among project stakeholders will decide so.
++ `SUPERSEEDED by ADR-xxx`: ADR which has been superseded by a new ADR.
++ `ABANDONED`: the ADR is no longer pursued by the original authors.
+
+## Language used in ADR
+
++ The context/background should be written in the present tense.
++ Avoid using a first, personal form.
