+### 2.1 Change community tags
+
+Separately to a general market change proposal, proposers can create a proposal to add or remove lists of free-text string community tags to a market. Although these proposals change only a single market, it is possible that these tags will be used to control external behaviour of systems interacting with the vega chain, therefore they do not allow for voting using ELS and instead must be voted through by the general pool of token holders as with any other proposal. The maximum length of a community tags is specified by the network parameter `governance.proposal.market.maxCommunityTagLength`. The community tags on a market are controlled by a single proposal type, `UpdateCommunityTags` with a structure akin to:
+
+```proto
+message UpdateCommunityTags {
+  string marketId;
+  repeated string addTags;
+  repeated string removeTags;
+}
+```
+
+allowing proposals to add and remove tags independently from others.
+
+The following network parameters will decide how these proposals are treated:
+`governance.proposal.updateCommunityTags.maxClose` e.g. `720h`,
+`governance.proposal.updateCommunityTags.minClose` e,g. `168h`,
+`governance.proposal.updateCommunityTags.maxEnact` e.g. `720h`,
+`governance.proposal.updateCommunityTags.minEnact` e,g. `168h`,
+`governance.proposal.updateCommunityTags.minProposerBalance` e.g. `1000000000000000000` i.e. 1 VEGA,
+`governance.proposal.updateCommunityTags.minVoterBalance`   e.g. `1000000000000000000` i.e. 1 VEGA,
+`governance.proposal.updateCommunityTags.requiredMajority`  e.g. `0.66`,
+`governance.proposal.updateCommunityTags.requiredParticipation` e.g. `0.05`.
+
+Note: Although community tags cannot be amended in an update market proposal, they may be included in the same batch proposal as one.
+
 ## 3. Change network parameters
 
 [Network parameters](./0054-NETP-network_parameters.md) that may be changed are described in the _Network Parameters_ spec, this document for details on these parameters, including the category of the parameters. New network parameters require a code change, so there is no support for adding new network parameters.
